Product details

What this tantalum capacitor brings to the board

The TPSB157M004R0250: With a ±20% tolerance and 250 mOhm equivalent series resistance (ESR), this part is designed for general-purpose filtering and decoupling in low-voltage DC rails.

ESR and capacitance — what 250 mOhm and 150 µF mean for your rail

The 250 mOhm ESR at 150 µF means this cap handles ripple current without excessive self-heating — a key parameter for bulk decoupling on a 4 V supply rail where the ripple current stays under a few hundred mA RMS.

Frequently asked questions

Can TPSB157M004R0250 be replaced by a similar part?

The TPS series includes other capacitance/voltage variants in the same B case size, but a direct drop-in substitute would require verifying the ESR and voltage rating against your circuit's requirements.

What is the ESR of TPSB157M004R0250?

The equivalent series resistance is 250 mOhm, which governs the ripple current handling and self-heating in decoupling applications.
