For a 0805 case, that limit is roughly 0.1 W at 25 °C, derating to zero at 125 °C — so the ripple current budget is about 110 mA RMS at room temperature, dropping to near zero at the top end of the range. The molded case (Type Molded) provides mechanical protection against vibration and moisture ingress better than a conformally-coated chip, though it is not hermetic. ## Lifecycle and ordering posture","metaTitle":"TAJP225M020RNJ KYOCERA AVX TAJ Series 2.2 µF 20 V Molded","metaDescription":"TAJP225M020RNJ: KYOCERA AVX TAJ series, 2.2 µF, 20 V, ±20%, 0805, 8.3 Ohm ESR, -55 to 125 °C.

This value determines the capacitor's self-heating under ripple current and its filtering effectiveness at higher frequencies. For a 2.2 µF part in an 0805 case, an 8.3 Ohm ESR means the impedance is dominated by resistance above roughly 10 kHz, so the capacitor behaves more like a resistor than a capacitor at switching-regulator frequencies — plan for that in your output filter design."},{"question":"Can TAJP225M020RNJ be used in high-frequency applications?","answer":"At frequencies above about 10 kHz, the 8.3 Ohm ESR dominates the impedance, so the capacitor's effectiveness as a bypass or filter element drops off. For high-frequency decoupling (above 1 MHz), a ceramic capacitor with lower ESR is a better choice. This tantalum is suited for bulk storage and low-frequency filtering on power rails where the ripple frequency is below a few kilohertz."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/kyocera-avx/TAJP225M020RNJ","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/kyocera-avx/TAJP225M020RNJ when reusing this data.
