Product details

680 µF in a 2917 case — bulk decoupling for tight boards

The TAJE687K004RNJ packs 680 µF into a 2917 (7343 Metric) molded case — a standard footprint for high-density tantalum capacitors on surface-mount assemblies. Rated at 4 V with ±10% tolerance, it suits low-voltage rails where the voltage margin stays above the recommended derating floor. The 900 mOhm ESR sets a ripple-current ceiling; this part is a bulk-storage choice for low-ripple digital rails, not a high-frequency decoupling cap.

The molded case construction (Type Molded) provides mechanical stability across thermal cycling, with no conformal-coat step needed on the capacitor body.

Frequently asked questions

What is the footprint for TAJE687K004RNJ?

The part uses the 2917 (7343 Metric) case size — 7.30 mm x 4.30 mm footprint with a seated height of 4.30 mm max. This is a standard tantalum capacitor land pattern; the manufacturer size code is E.
