293D107X9010D2TE3 Descripción general
A solid tantalum capacitor is a polarized surface-mount capacitor that uses sintered tantalum powder as the anode and a manganese dioxide or polymer cathode to achieve high volumetric capacitance density. Compared to aluminum electrolytic capacitors, tantalum parts deliver higher capacitance per unit volume, lower ESR, no dry-out failure mode, and superior frequency stability, making them the preferred choice for bulk decoupling and point-of-load filtering in switching power supplies, DC-DC converters, and analog circuits where reliability and small PCB footprint are required. The hypernym hierarchy is: tantalum capacitor -> electrolytic capacitor -> polarized capacitor -> capacitor -> passive component.
Key specifications include a 100 µF nominal capacitance with ±10% tolerance (per the "107" and "10%" codes in the part number), 10 V rated DC working voltage (per the "10" code), 0.6 ohm maximum ESR at 100 kHz / +25 °C, an operating temperature range of -55 °C to +85 °C (with voltage derating required above +85 °C up to +125 °C), and a maximum ripple current rating suitable for switch-mode power supply output filtering. The molded epoxy body provides mechanical robustness and supports automated pick-and-place assembly.
From an applications perspective, the 293D107X9010D2TE3 is commonly used as a bulk output capacitor on the secondary side of DC-DC converters (buck, boost, and SEPIC topologies), as a bypass/decoupling element next to FPGAs, ASICs, and microcontrollers, in point-of-load regulators downstream of intermediate bus voltages, in industrial control and instrumentation, and in automotive non-safety electronics where commercial-grade reliability is sufficient. The part meets IEC specification QC300801/US0001 and EIA 535BAAC standard requirements.
When designing with this part, observe the rated voltage derating guidelines recommended by Vishay for tantalum capacitors (typically 50% or less of rated voltage for reliability) and respect polarity during board layout and assembly. Reverse bias, even well below a ratings threshold, can cause dielectric breakdown and catastrophic failure. ESR at the switching frequency of the surrounding converter should be verified to ensure adequate ripple handling.

Aplicaciones típicas
293D107X9010D2TE3 es adecuado para 6 aplicacións: DC-DC Converter Output Bulk Filter, FPGA / ASIC Decoupling Bypass, Point-of-Load (POL) Regulator Input Filter, Industrial Control & Instrumentation, Audio Amplifier Power Supply Decoupling, Automotive Infotainment & Body Electronics (Non-Safety).
DC-DC Converter Output Bulk Filter
The 293D107X9010D2TE3 fits DC-DC converter output bulk filtering because its 100 µF capacitance at 10 V working voltage and 0.6 ohm maximum ESR at 100 kHz provide effective smoothing for buck, boost, and SEPIC topologies with 1-3 A load currents. Place this part directly at the converter output, immediately downstream of the inductor, to absorb load transients and reduce output ripple voltage to approximately 60-180 mV peak-to-peak depending on ripple current amplitude. Compared to aluminum electrolytic capacitors, the solid tantalum dielectric delivers stable ESR over the full -55 °C to +85 °C operating range with no dry-out aging mechanism, extending converter service life in industrial and telecom applications.
Recomendado
FPGA / ASIC Decoupling Bypass
The 293D107X9010D2TE3 is well suited as a local bulk-decoupling element at FPGA and ASIC supply pins because its 100 µF capacitance handles large load steps during logic-state changes while the 0.6 ohm ESR at 100 kHz damps the resulting supply transients. For multi-rail FPGAs (core, I/O, transceiver, auxiliary), one 293D107X9010D2TE3 per major rail complements the small MLCC bypass network (0.1 µF + 10 nF) that handles high-frequency decoupling. The D-case 2917 footprint keeps the bulk capacitor directly beneath the BGA land area, minimizing PCB loop inductance. Designers should still verify inrush current behavior at power-up because solid tantalum capacitors have a known surge-current failure mode if not properly voltage-derated.
Recomendado
Point-of-Load (POL) Regulator Input Filter
The 293D107X9010D2TE3 functions as an input-side bulk filter for point-of-load regulators fed from a 12 V intermediate bus because its 100 µF / 10 V rating provides headroom for bus transients and its 0.6 ohm ESR helps attenuate switching noise reflected from downstream regulators. Place the capacitor at the POL input pin with the shortest possible trace to both the input source and the regulator, since input-side inductance is highly inductive and can create voltage ringing during load steps. Compared to aluminum polymer capacitors, this tantalum part offers tighter capacitance tolerance (±10%) for predictable input-impedance calculations. It is typically paired with smaller ceramic bypass capacitors (1 µF to 10 µF X7R) for high-frequency filtering.

Industrial Control & Instrumentation
The 293D107X9010D2TE3 is a strong fit for industrial control and instrumentation designs where its industrial-grade -55 °C to +85 °C operating range, stable electrical parameters, and IEC QC300801/US0001 / EIA 535BAAC compliance support reliable long-life operation. Typical uses include PLC output modules, sensor signal conditioning boards, and process-control instrumentation where the bulk capacitor smooths the rectified line input or filters the DC bus feeding analog front-end circuitry. The 10 V rating suits 5 V and 3.3 V analog rails with proper derating, and the molded epoxy body provides mechanical robustness for vibration-prone factory environments. Designers should observe the Vishay voltage-derating guideline of typically 50% for maximum reliability.
Recomendado
Audio Amplifier Power Supply Decoupling
The 293D107X9010D2TE3 supports local power-supply decoupling for Class-D and Class-AB audio amplifiers because its 100 µF capacitance and 0.6 ohm ESR at 100 kHz effectively attenuate ripple and switching noise on the amplifier's supply pin. Place the capacitor directly across the amplifier supply and ground returns to prevent audio-band modulation of supply noise that would degrade THD+N performance. Compared to ceramic capacitors, the tantalum dielectric's slower discharge characteristic helps deliver instantaneous peak current demands during transients (e.g., kick-drum peaks) without audible supply droop. The molded D-case footprint fits standard amplifier PCB layouts adjacent to large inductors and transformers.
Recomendado
Automotive Infotainment & Body Electronics (Non-Safety)
The 293D107X9010D2TE3 can be used in automotive infotainment, instrument-cluster, and body-electronics modules that do not require AEC-Q200 qualification, such as headrest monitors, rear-seat entertainment, and accessory lighting. Its 100 µF / 10 V rating suits 5 V and 8 V internal rails in these systems, and the -55 °C to +85 °C operating range covers typical cabin temperatures. Designers should pair this part with AEC-Q200-qualified bypass MLCCs to ensure the overall module meets automotive reliability expectations; for safety-critical ECUs (ABS, airbag, ADAS), select a dedicated automotive-grade tantalum capacitor instead. Always respect the Vishay voltage-derating guideline to mitigate inrush surge-current failures.

Notas de diseño
Solid tantalum capacitors have a well-documented surge-current failure mode: applying rated voltage to a discharged tantalum capacitor can create a high inrush current that locally heats the MnO2 cathode, potentially causing dielectric breakdown and short-circuit failure. To mitigate this, apply at least 50% voltage derating (i.e., design for ≤5 V continuous on a 10 V part), add a soft-start / inrush-limiting resistor or NTC thermistor on power-up rails, and verify the manufacturer's recommended derating curve for the specific case code before finalizing the design.
Estimated: At a typical DC-DC converter output of 5 V with 1 A peak-to-peak ripple current at 100 kHz, the 293D107X9010D2TE3 contributes approximately 600 mV of ESR-induced ripple (1 A × 0.6 ohm) plus the capacitive reactance component. Designers should combine this part with smaller MLCC bypass capacitors (typically 10 µF X7R 1210) in parallel to attenuate both ESR-induced ripple at the switching frequency and high-frequency noise above 1 MHz. Verify combined impedance Z(f) at the converter's switching frequency using the manufacturer's SPICE model.
Place the 293D107X9010D2TE3 as close as practical to the IC supply pin it is decoupling, keeping trace length below 5 mm to minimize parasitic inductance that would otherwise create voltage ringing at high di/dt load steps. Use wide copper pours (≥1 oz) for both anode and cathode pads to handle the ripple current without resistive losses. Refer to the Vishay 293D datasheet recommended land pattern (IPC-7351 standard) for the exact pad geometry. Polarity bar must be respected: the anode pad (+) is on the side marked with a bar on the molded body; reverse mounting causes immediate dielectric failure.
Solid tantalum capacitors dissipate I²R losses from ripple current; the resulting self-heating must be limited to keep the case temperature below the upper operating limit. At 1 A RMS ripple at 100 kHz and 0.6 ohm ESR, internal dissipation is approximately 0.6 W, which can raise the case temperature 10-20 °C above ambient depending on PCB copper area. Provide adequate copper thermal mass around the D-case pads, and derate the ripple current by 30-50% above +85 °C per Vishay guidelines. The molded epoxy body dissipates less efficiently than larger aluminum electrolytic capacitors at the same ripple rating.
