Product details

15 µF, 20 V — bulk decoupling for 12 V rails

The TAJB156M020Y: 15 µF at 20 V with ±20% tolerance — this is the bulk decoupling cap for a 12 V rail that sees occasional transients up to 16 V, leaving 4 V of headroom below the 20 V rating. The 2 Ohm ESR means it handles moderate ripple current but will self-heat more than a low-ESR polymer cap; keep the ripple current below ~200 mA RMS at 85°C to stay inside the thermal derating curve.

The molded case (type: Molded) and surface-mount 1411 (3528 Metric) package make it a direct fit for standard pick-and-place reflow assembly.

Frequently asked questions

What is the closest replacement for TAJB156M020Y?

No official second-source or successor is listed. Any functional equivalent would need the same 15 µF, 20 V, ±20% tolerance, size code B, and molded 1411 (3528 Metric) package. The TAJ series includes many capacitance/voltage variants; confirm the BOM position before substituting.
