Automotive-grade molded tantalum for power rail filtering
The TPSC226K010T0180 is a molded tantalum capacitor from the KYOCERA AVX TPS series, rated at 22 µF ±10% with a 10 V working voltage. Its 180 mOhm ESR at 100 kHz sets the ripple current capability and power dissipation floor for decoupling and bulk storage on automotive power rails. AEC-Q200 qualification means this part has passed the automotive-grade stress tests — temperature cycling, moisture resistance, and mechanical shock — making it suitable for under-hood and cabin electronics where reliability is non-negotiable.
ESR and thermal endurance at 125°C
The 180 mOhm ESR at 100 kHz is a key parameter for power supply output filtering — lower ESR means less self-heating and better ripple attenuation. The 2000-hour lifetime at 125°C defines the thermal budget: in a 105°C ambient, the capacitor sees a 20°C margin, extending operational life beyond the rated hours. Operating range from -55°C to 125°C covers the full automotive temperature envelope, including cold cranking and hot soak conditions.
