Product details

This combination is typical for bulk decoupling on 3.3 V or 1.8 V power rails where the voltage derating (typically 50–80 % of rated voltage) keeps the part within its safe operating area. With a 1.2 Ohm ESR, the ripple current capability is limited compared to low-ESR polymer or MLCC alternatives — expect a ripple current rating in the range of 0.5–0.8 A at 100 kHz, which suits moderate-load decoupling rather than high-ripple switching regulators.

2312 case — standard footprint for rework

The 2312 (6032 Metric) case measures 6.00 mm x 3.20 mm with a seated height of 1.50 mm max.
