A lower ESR means less self-heating under AC ripple, which directly extends the capacitor's service life in high-frequency switching applications. ## Full temperature range and case details Operating from -55°C to 125°C, this cap covers the full industrial and military temperature envelope — no derating needed for most automotive under-hood or outdoor telecom enclosures. The ±10% tolerance is tighter than the standard ±20% for tantalum electrolytics, which matters when the capacitance value sits inside a filter pole or timing circuit where the tolerance band directly affects the corner frequency.","metaTitle":"KYOCERA AVX TPSE158K004R0050 TPS Series, 1500 µF, 4 V","metaDescription":"KYOCERA AVX TPSE158K004R0050 molded tantalum capacitor, 1500 µF, 4 V, 50 mOhm ESR, ±10%, -55°C to 125°C, 2917 case.

This is the equivalent series resistance at the capacitor's self-resonant frequency. A 50 mOhm ESR means the cap can handle higher ripple current without excessive internal heating compared to a higher-ESR tantalum, making it suitable for output filtering in switching regulators where the AC ripple current is significant."},{"question":"What temperature range does TPSE158K004R0050 cover?","answer":"This covers full industrial, military, and most automotive under-hood applications without derating."},{"question":"What is the case size and package for TPSE158K004R0050?","answer":"It is a surface-mount molded tantalum delivered in Tape & Reel packaging."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/kyocera-avx/TPSE158K004R0050","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/kyocera-avx/TPSE158K004R0050 when reusing this data.
