The ESR is the spec that sets the ripple current limit and the output voltage transient response in a switching regulator — a 400 mOhm cap can handle roughly 700 mA ripple at 85°C before self-heating becomes a concern. The molded case (size C, 6.00 mm x 3.20 mm x 2.80 mm) gives it a standard surface-mount footprint that reflows on a standard profile.","metaTitle":"TPSC226M020R0400 — 22 µF 20 V Molded Tantalum, 400 mOhm ESR","metaDescription":"KYOCERA AVX TPS series 22 µF ±20% molded tantalum cap, 20 V rated, 400 mOhm ESR, -55°C to 125°C, size C (2312).

The higher ESR on the R0400 means it will run hotter for the same ripple current and have a slower transient response. If your circuit was designed around the 300 mOhm limit, the R0400 may not be a drop-in swap without rechecking the thermal and transient margins."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/kyocera-avx/TPSC226M020R0400","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/kyocera-avx/TPSC226M020R0400 when reusing this data.
