TCNT476M016R0150E Overview
A polymer tantalum capacitor is a type of tantalum capacitor in which the conventional manganese dioxide cathode is replaced with a conductive polymer (typically PEDOT). This construction removes the risk of ignition failure that affects MnO2 tantalum parts under voltage surges, while providing much lower ESR, higher ripple current capability, and benign failure mode (the part simply fails open rather than burning). Polymer tantalum sits in the taxonomy: capacitor -> tantalum capacitor -> molded chip tantalum -> polymer tantalum -> surface-mount polymer tantalum.
Key features include 47 uF nominal capacitance, 16 V rated voltage, 20% capacitance tolerance, 150 mOhm maximum ESR measured at 100 kHz, and an operating temperature range of -55C to +105C. The molded 1210 case is footprint-compatible with the EIA 1210 land pattern and offers low profile (~1.9 mm typical) suitable for dense PCB layouts under BGAs and near connector shields.
Typical applications include decoupling for low-voltage CPU/GPU cores, point-of-load bypass on telecom/networking line cards, bulk hold-up on solid-state drives, and low-profile audio/display modules. The polymer construction makes this part especially attractive where designers want the energy density of tantalum but need the safety and ripple performance of polymer.
When designing with this part, derate the applied voltage by at least 20% (target ~12.8 V or less) for steady-state reliability, and reserve the surge headroom for hot-plug and transient events. Avoid placing the part immediately downstream of large inductive loads; the polymer's benign failure mode helps, but series impedance still affects surge exposure.

Typical Applications
TCNT476M016R0150E is suitable for 6 applications: 12V Rail Bulk Decoupling for Networking Line Cards, Solid-State Drive (SSD) Bulk Hold-Up, Industrial IoT Gateway POL Output Filter, Automotive Infotainment 12V Audio Decoupling, Server VRM Bulk Decoupling, Display Backlight LED Driver Bypass.
12V Rail Bulk Decoupling for Networking Line Cards
The TCNT476M016R0150E provides 47 uF bulk capacitance on 12 V power rails feeding switch ASICs, PHY transceivers, and timing devices on networking line cards. Its 150 mOhm ESR at 100 kHz is well below typical MnO2 tantalum of the same CV, dramatically reducing voltage droop during transient load steps. The polymer cathode's benign failure mode and 16 V rating (derated to ~12.8 V steady-state) make it ideal for hot-swap telecom bays where inrush surges are routine. Use 1-2 pieces per 12 V rail near the POL converter input to suppress input ripple below 30 mV pk-pk.

Solid-State Drive (SSD) Bulk Hold-Up
The TCNT476M016R0150E supplies 47 uF bulk capacitance on the 12 V input of SSD power planes, where it holds up the rail during hot-unplug events long enough for housekeeping writes to complete. Its 1210 (1411 metric) case fits comfortably under BGA NAND packages and provides a low 1.9 mm profile suitable for M.2 and 2.5-inch form factors. The polymer's 150 mOhm ESR keeps ripple under 50 mV at typical SSD switching loads. Designers commonly place 2-3 pieces in parallel on the 12 V input, achieving ~140 uF effective bulk with sub-50 mOhm combined ESR.
Recommended
Industrial IoT Gateway POL Output Filter
The TCNT476M016R0150E serves as the output filter capacitor on the 12 V POL (point-of-load) rails of industrial IoT gateways that carry sensor data into Wi-Fi, LoRa, or LTE modules. Its 16 V rating handles the full 12 V rail plus transient margin, while the 150 mOhm ESR ensures the POL converter stays stable with ceramic-only output capacitance. The polymer's benign failure mode is critical in fan-less industrial enclosures where capacitor failure must not cause ignition. Place one piece per POL output as the bulk-energy reservoir for sensor bursts.

Automotive Infotainment 12V Audio Decoupling
The TCNT476M016R0150E decouples 12 V rails feeding audio DACs, Class-D amplifiers, and infotainment processors in non-engine-bay automotive applications. The 105C upper temperature rating covers under-dash and center-console thermal environments. Its 150 mOhm ESR keeps amplifier supply noise low, preserving audio dynamic range. For engine-bay or direct battery-connected rails, choose an AEC-Q200 qualified alternative - the standard TCNT476M016R0150E is suited to cabin-electronics applications only. One piece per amplifier supply pin is typical.
Recommended
Server VRM Bulk Decoupling
The TCNT476M016R0150E provides bulk decoupling at the input side of buck VRMs feeding server CPU cores, where 12 V intermediate bus current can exceed 30 A. The 150 mOhm ESR combined with 47 uF bulk capacitance reduces input ripple and dampens the resonant interaction between the VRM and upstream 12 V bus. Multiple pieces are placed in parallel arrays around the VRM input inductor. The polymer's benign failure mode is critical in 24/7 server environments where any capacitor failure must not propagate into a fire event.
Recommended
Display Backlight LED Driver Bypass
The TCNT476M016R0150E bypasses the 12 V input of LED backlight drivers in monitor, TV, and industrial HMI panels. The polymer's low ESR absorbs the high-frequency switching current spikes from boost/flyback LED drivers, reducing conducted EMI back onto the 12 V rail. Its 1210 footprint is compatible with the dense PCB layouts typical of edge-lit LED panels. One piece per LED driver IC is typical, sometimes two in parallel for >1 A peak LED current applications. The 105C rating covers the elevated ambient of closed-display enclosures.

Key Differentiators
- Polymer cathode enables benign failure mode (vs Legacy MnO2 tantalum 47uF 16V 1210)
- Substantially lower ESR than MnO2 tantalum equivalents (vs MnO2 tantalum 47uF 16V 1210 (typically 300-400 mOhm))
- TCN series enables J-CAP undertab variant (vs Standard top-overland polymer tantalum)
Design Notes
Polymer tantalum capacitors have a benign failure mode (open) but can still be damaged by reverse polarity and by overvoltage transients that exceed the surge rating. Always respect the polarity-bar marking on the molded case, and add a TVS or zener clamp upstream if the input rail can spike above 18 V (typically 1.2x the rated voltage for a few ms).
Use the IPC-7351 EIA 1210 land pattern with approximately 2.80 mm x 1.60 mm pads. Place the part on the same copper plane as the load it decouples, with vias stitching the cathode pad to the inner ground plane for low-inductance return. Keep the trace length between the capacitor and the load IC under 5 mm to maintain low ESL at the switching frequency of the converter.
Estimated: derate the applied steady-state voltage to 80% or less of the 16 V rating (~12.8 V) for reliability targets of 50,000+ hours at 60C, and to 50% (~8 V) for 105C continuous. AVX publishes per-series voltage-derating curves in the TCN datasheet family that supersede these estimates; consult them before finalizing the design.
