For a bulk tantalum capacitor in a 2917 case, this ESR determines the ripple current rating — lower ESR means the capacitor can handle more AC ripple without exceeding its internal temperature rise limit. It is the primary selection parameter after capacitance and voltage for power rail decoupling."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/kyocera-avx/TPSD337M004R0045","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/kyocera-avx/TPSD337M004R0045 when reusing this data.
