The ±10% tolerance and -55°C to 125°C operating range cover industrial and telecom environments where the capacitor sees both cold start and sustained heat near the rail. ## ESR and ripple — the so-what for the BOM The 50 mOhm ESR is the key parametric for a bulk tantalum — it sets the self-heating under ripple current. For a 1 A ripple at 100 kHz, the dissipation is about 50 mW, well within the package's thermal budget in still air. The molded case provides mechanical stability during reflow and resists cracking from board flex, a common failure mode for larger tantalum chips in high-vibration assemblies.","metaTitle":"TPSE477K010R0050 KYOCERA AVX TPS 470 µF 10 V 50 mOhm ESR","metaDescription":"KYOCERA AVX TPSE477K010R0050 TPS series tantalum capacitor, 470 µF, 10 V, 50 mOhm ESR, 2917 case.
