HCA55 Chip-Type Conductive Polymer Solid-Electrolyte Tantalum Capacitor

Product Description

Product Features:
1. Extremely low ESR and a relatively low ESL [equivalent series inductance], with a high resonant frequency, enabling use in higher‑frequency filtering circuits;
2. In the case of a benign failure mode, short circuits are unlikely to trigger fires or secondary breakdown effects, resulting in excellent safety performance.
3. When used in low‑impedance switching power supply circuits, it is insensitive to surge currents and voltages, requiring only a 10%–20% derating; under the same operating conditions, its failure rate is lower than that of conventional MnO₂‑based products.
4. Low internal resistance provides superior ripple‑handling capability, significantly reducing heat generation during filtering and high‑power discharging, resulting in improved filtering performance and discharge waveforms that more readily meet technical specifications.
5. Reliability is one order of magnitude higher than that of chip tantalum capacitors with manganese dioxide as the cathode.
6. The filtering circuit exhibits superior performance in attenuating high ripple, and the high‑power, high‑frequency discharge circuit achieves even better filtering.

Technical Specifications (All technical parameters are measured at 1 atmosphere and +25°C):
① Operating temperature range: -55°C to +125°C
② Nominal capacitance range: 0.68 to 680 μF at 100 Hz
③ Capacity tolerance: Class M (±20%);
④ DC Leakage Current (DCL): DCL ≤ 0.1CV; measured after charging at rated voltage for 5 minutes.
⑤ Equivalent Series Resistance (ESR): See the “Product Code and Specification Parameters” table.
⑥ Pin plating: Pure tin plating (standard); gold plating or tin–lead plating must be requested separately.
⑦ Soldering heat resistance: peak temperature 260°C, 10 s
