293D106X9016B2TE3 Overview
A solid tantalum capacitor is a polarized capacitor that uses tantalum metal as the anode with a manganese dioxide solid electrolyte, rather than a liquid electrolyte. Within the passive-component hierarchy, it sits under capacitors -> fixed capacitors -> electrolytic capacitors -> tantalum capacitors. Tantalum technology is preferred where volumetric efficiency (high capacitance per unit volume), stable electrical parameters over life, and low aging rates are required.
Key features of this TANTAMOUNT molded-case device include stable capacitance over temperature and life, a rated voltage of 16 V DC at +85 C (derated to +125 C), Β±10% tolerance, and a 2 ohm ESR in a molded case that provides mechanical robustness and superior moisture resistance versus uncoated chips. The TE3 suffix denotes lead-free, RoHS-compliant construction in tape-and-reel packaging for automated pick-and-place assembly.
Technically, the 293D series uses solid manganese dioxide cathode construction, which eliminates dry-out failure mechanisms common in aluminum electrolytics. Capacitance for the family spans 0.1 uF to 1000 uF, and this B-case variant balances capacitance density with a moderate ESR suited to general-purpose decoupling and filtering. Reverse-voltage capability is limited, so correct polarity must be maintained on the PCB.
Typical applications include industrial control power-supply decoupling, telecom equipment DC filtering, portable and battery-powered device bulk storage, and general-purpose output filtering on DC-DC converters, where stable parameters and compact size matter.
A key design consideration is voltage derating: industry practice recommends operating solid tantalum capacitors at 50% or less of rated voltage on high-impedance or ripple-current-prone rails, so the 16 V rating is best applied at 8 V or lower.

Typical Applications
293D106X9016B2TE3 is suitable for 6 applications: Industrial Power-Supply Decoupling, Telecom Equipment DC Filtering, Battery-Powered Portable Devices, DC-DC Converter Output Filtering, Analog and Sensor Rail Stabilization, General-Purpose Bulk Storage and Hold-Up.
Industrial Power-Supply Decoupling
The 293D106X9016B2TE3 fits industrial control power rails because its 10 uF capacitance remains stable regardless of DC bias, unlike class II MLCCs that can lose half their capacitance under bias, and its solid manganese dioxide construction does not dry out over life like liquid-electrolyte aluminum capacitors. In PLC and motor-control boards, it is placed at each supply pin group as bulk decoupling after a switching pre-regulator; its 2 ohm ESR provides useful damping for controller stability. Operation from -55 C to +125 C (with derating above +85 C) covers factory-floor ambient extremes. Apply 50% voltage derating on noisy or high-impedance rails.
Recommended
Telecom Equipment DC Filtering
Telecom line cards and network equipment require bulk capacitance with stable parameters over long service life, which is precisely the stated design intent of the Vishay TANTAMOUNT 293D series. The 10 uF, 16 V, Β±10% characteristics of the 293D106X9016B2TE3 make it suitable for filtering intermediate DC rails between 5 V and 8 V, where its 2 ohm ESR smooths switching ripple without requiring multiple paralleled ceramics. The molded B case resists moisture and mechanical stress in card-cage environments, and tape-and-reel TE3 packaging supports high-volume automated placement. RoHS-compliant lead-free construction simplifies global deployment.
Recommended
Battery-Powered Portable Devices
The volumetric efficiency of solid tantalum technology is the core reason to specify the 293D106X9016B2TE3 in portable and battery-powered products: at only 3.5 x 2.8 x 1.9 mm, the B case delivers 10 uF in minimal board area, freeing space for larger batteries. Its capacitance does not drop with the falling battery voltage that plagues bias-sensitive MLCCs, so regulator loop gain and hold-up characteristics remain predictable from full charge to cutoff. The 2 ohm ESR also limits inrush charging current spikes that can disturb battery-management circuits. Design with 50% derating for cells reaching near the rated 16 V.
Recommended
DC-DC Converter Output Filtering
Many switching-regulator controllers specify a minimum output capacitor ESR for loop stability; the 293D106X9016B2TE3's 2 ohm ESR lands in the stable region for legacy controllers where ultra-low-ESR ceramics would cause oscillation or require artificial ESR additions. A 10 uF solid tantalum on a 5 V output provides reliable bulk filtering with capacitance that stays constant across load and temperature, holding output ripple predictable. Because solid tantalum tolerates sustained ripple current better than marginal aluminum parts when properly derated, it is a dependable choice for 5-8 V secondary rails in industrial converters.
Recommended
Analog and Sensor Rail Stabilization
Analog front ends and sensor boards benefit from the 293D106X9016B2TE3 because its capacitance stability (Β±10% over life and temperature) keeps low-frequency noise filtering and reference-decoupling corner frequencies where the designer placed them. A 10 uF tantalum on the analog supply node, followed by a small LDO or ferrite bead, forms a classic quiet-rail topology; unlike ceramics, the tantalum introduces no piezoelectric microphony that can inject noise into precision measurement chains. Its 16 V rating covers common 12 V analog buses when derated, and the molded case tolerates conformal coating used in instrumentation.
Recommended
General-Purpose Bulk Storage and Hold-Up
The 293D106X9016B2TE3 serves as compact bulk energy storage on microcontroller, memory, and interface boards where momentary load transients exceed regulator bandwidth. Its stable 10 uF capacitance and solid-electrolyte construction guarantee repeatable hold-up behavior, while the 2 ohm ESR spreads transient charge delivery to limit di/dt spikes. The B case 3528 metric footprint is compatible with the vast majority of tantalum layouts, simplifying second-sourcing, and the TE3 tape-and-reel packing supports high-volume SMT assembly. Applications include embedded industrial controllers, set-top boxes, and general-purpose telecom auxiliary rails.

Key Differentiators
- 16 V rating for 8 V-class derated rails (vs 293D106X9010B2TE3)
- Lower voltage headroom cost vs 20 V variant (vs 293D106X9020B2TE3)
- Specified 2 ohm ESR for controller stability (vs T491B106K016AT)
Design Notes
Voltage derating is the single most important reliability rule for solid tantalum capacitors. Apply 50% derating: use the 16 V rated 293D106X9016B2TE3 only on rails of 8 V or lower, and choose the 20 V rated 293D106X9020B2TE3 for 9-12 V rails. On high-impedance or low-current sources with limited series resistance, derate further. Reverse polarity must never occur; note that on tantalum capacitors the marking bar denotes the POSITIVE terminal, opposite to aluminum electrolytics - a frequent assembly-line error.
The 2 ohm ESR defines ripple and transient behavior: 100 mA of ripple current produces 200 mV of output ripple across this capacitor. Estimated inrush into a discharged 10 uF part is small, but on hot-plug rails add series impedance or an NTC if the upstream source impedance is very low. Some older switching controllers (e.g., MC34063 designs) need a minimum output-capacitor ESR for stability - this part satisfies that, whereas low-ESR ceramic-only output networks may oscillate on such controllers.
Place the capacitor close to the regulator output or IC supply pin with short, wide traces to the anode pad; the cathode bar must align with the ground plane side of the layout to guarantee correct polarity at assembly. Keep the ground return path low-inductance. Reflow profile per Vishay datasheet guidance for molded tantalum chips (peak <= 260 C, MSL 1). Avoid locating the part near hot components above +125 C ambient; derate applied voltage above +85 C per the datasheet derating curve.
