That ESR figure is the key selection parameter for power-supply decoupling — it governs the ripple current the part can handle before self-heating becomes a derating issue. This is a standard footprint for medium-bulk tantalum caps; the pad layout matches the common 7343-31 pattern used across the industry. Rated for -55°C to 125°C, it covers the full industrial temperature range. ## What the 35 mOhm ESR means for your circuit A 35 mOhm ESR at 100 kHz is low for a 470 µF tantalum — it keeps the ripple voltage across the capacitor within a few tens of millivolts for load transients up to a couple of amps. For a 1 A step load, expect about 35 mV of ripple from the ESR alone, with the capacitive droop adding another 10-15 mV depending on the switching frequency. This ESR also sets the ripple-current rating. A rough bench rule: at 85°C ambient, a 35 mOhm part in still air can handle about 1.5 A RMS before the internal temperature rise hits 10°C. For higher ripple, derate the voltage or add forced airflow — the datasheet's ripple-current curve is the final word. The ±10% tolerance is standard for tantalum electrolytics. For decoupling applications, the actual capacitance at 4 V bias is typically within 5% of the nominal; the tolerance matters more for timing circuits or filters where the RC time constant is critical. ## Active lifecycle — sourcing posture Sourced through authorized distribution channels. The part carries standard KYOCERA AVX warranty and lot traceability.","metaTitle":"KYOCERA AVX TPSE477K004R0035 Tantalum Cap, 470 µF, 4 V","metaDescription":"KYOCERA AVX TPSE477K004R0035 molded tantalum capacitor, 470 µF, 4 V, ±10%, 35 mOhm ESR, 2917 package.
