Product details

22 µF, 20 V, 400 mOhm ESR — TPS series molded tantalum

The TPSC226M020R0400: This is a 22 µF ±20% molded tantalum capacitor rated at 20 V from KYOCERA AVX's TPS series, with 400 mOhm ESR at 100 kHz. The ESR is the spec that sets the ripple current limit and the output voltage transient response in a switching regulator — a 400 mOhm cap can handle roughly 700 mA ripple at 85°C before self-heating becomes a concern.

The molded case (size C, 6.00 mm x 3.20 mm x 2.80 mm) gives it a standard surface-mount footprint that reflows on a standard profile.

Frequently asked questions

What is the ESR of TPSC226M020R0400?

The equivalent series resistance is 400 mOhm at 100 kHz, typical for a 22 µF/20 V molded tantalum in the C case size. This ESR value drives the ripple current rating and the output voltage transient response in a DC-DC converter.

Can I use TPSC226M020R0400 as a replacement for TPSC226M020R0300?

The two parts share the same capacitance (22 µF), voltage (20 V), and tolerance (±20%), but the ESR differs — 400 mOhm for the R0400 versus 300 mOhm for the R0300. The higher ESR on the R0400 means it will run hotter for the same ripple current and have a slower transient response. If your circuit was designed around the 300 mOhm limit, the R0400 may not be a drop-in swap without rechecking the thermal and transient margins.
