Product details

6.8 µF, 6.3 V, 3 Ω ESR — BOM-fit parametric note

The TAJB685M006RNJ: The B case size (EIA 3528-21, 3.50 mm × 2.80 mm footprint, 2.10 mm seated height) fits the standard 1411 (3528 Metric) land pattern — no pad geometry adjustment needed for reflow assembly.

Active lifecycle — no last-time-buy pressure

No stock-holding claim — quoted per RFQ.

Footprint and board-fit checklist

The manufacturer size code B maps to the standard EIA 3528-21 land pattern — the same footprint used by other TAJ-series B-case parts, so a single pad layout serves multiple capacitance/voltage variants in the same size code. Surface-mount assembly with tape-and-reel packaging (Cut Tape also available).

Frequently asked questions

What is the footprint of TAJB685M006RNJ?

The manufacturer size code B matches the EIA 3528-21 pad geometry.

Is TAJB685M006RNJ RoHS compliant?

The TAJB685M006RNJ is listed as a General Purpose capacitor from the TAJ series. KYOCERA AVX TAJ series molded tantalum capacitors are RoHS compliant by default — no RoHS exemption flag appears on the product record.

Can I replace TAJB685M006RNJ with a different voltage rating?

A higher-voltage-rated tantalum in the same B case size (e.g., 10 V or 16 V) will physically fit the same 1411 footprint, but the capacitance value and ESR will differ. Derating to 50% of rated voltage is standard practice for tantalum reliability — a 6.3 V part should see no more than 3.15 V DC bias. If your circuit runs at 5 V, a 10 V rated part in the same case is a safer replacement.
