The ±10% tolerance and 2 Ohm ESR are the numbers that matter for decoupling and filter applications: the ESR sets the ripple voltage at the switching frequency, and the 25 V rating gives headroom on a 12 V or 5 V rail. At 6.8 µF and 2 Ohm ESR, the self-resonant frequency sits in the low-MHz range. For a 100 kHz buck converter, the ripple voltage at the output is roughly I_ripple × ESR — a 100 mA ripple current produces 200 mV of ripple. If that is too high, a lower-ESR tantalum or a ceramic in parallel is the fix.","metaTitle":"TAJW685K025RNJ KYOCERA AVX TAJ Series 6.8 µF 25 V Molded","metaDescription":"TAJW685K025RNJ: 6.8 µF ±10%, 25 V, 2 Ohm ESR, -55 to +125 °C.

The footprint matches the standard 2312 land pattern — no special pad geometry required."},{"question":"What is the ESR of TAJW685K025RNJ and why does it matter?","answer":"The ESR is 2 Ohm. This value directly determines the ripple voltage in a power rail decoupling application: for a given ripple current, the voltage ripple equals I × ESR. A 2 Ohm ESR is moderate for a 6.8 µF tantalum; if the ripple budget is tight, consider a lower-ESR part or a parallel ceramic."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/kyocera-avx/TAJW685K025RNJ","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/kyocera-avx/TAJW685K025RNJ when reusing this data.
