A 500 mOhm ESR at 100 kHz means the self-heating at the rated ripple current is manageable for most low-power rails, but a high-frequency buck converter drawing 1 A ripple will push the internal temperature rise above the 125°C limit if derating is ignored. For a hot-side application like a base-station power module or an engine-control unit, the 125°C rated life is the ceiling — the actual lifetime doubles for every 10°C drop below that, so at 85°C ambient the expected life extends well beyond 10,000 hours. Packaging options include Tape & Reel and Cut Tape, making it suitable for both prototype assembly and production reflow. The molded case construction gives consistent dimensional tolerance for pick-and-place. ## Lifecycle and sourcing posture Listed as Active on the manufacturer records — no last-time-buy or phase-out notice is in effect. The TPST107M004R0500 remains a current-production part, sourced through authorized distribution channels.","metaTitle":"KYOCERA AVX TPST107M004R0500 TPS Series 100 µF 4 V Tantalum","metaDescription":"Active KYOCERA AVX TPST107M004R0500 molded tantalum capacitor, 100 µF ±20%, 4 V, 500 mOhm ESR at 100 kHz, 125°C rated.

This value determines how much ripple current the part can handle before self-heating exceeds the rated temperature. For a 100 µF tantalum in a 4 V rail, 500 mOhm is typical for general-purpose decoupling — it will handle the ripple from a low-power LDO or a modest switching regulator without excessive heating."},{"question":"How do I get current pricing and availability for TPST107M004R0500?","answer":"This part is sourced to order against an RFQ."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/kyocera-avx/TPST107M004R0500","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/kyocera-avx/TPST107M004R0500 when reusing this data.
