Product details

2.2 µF, 25 V — Molded tantalum for tight board-space

The F381E225MMA is a molded tantalum capacitor from the KYOCERA AVX F38 series, rated 2.2 µF at 25 V with ±20% tolerance. The 0603 (1608 Metric) footprint and 0.90 mm seated height fit dense PCB layouts where a standard 0805 or 1206 tantalum would crowd adjacent passives. ESR is 500 mOhm at 100 kHz, which keeps ripple-induced heating manageable in decoupling and filtering roles — a typical 100 mA ripple current dissipates about 5 mW, well within the thermal budget of the molded case.

Operating range and lifetime — industrial-grade margin

The 1000-hour lifetime at 85°C is typical for molded tantalums — derate voltage and ripple current above 85°C to stay within the safe operating area. The manufacturer size code M corresponds to the 0603 case.

Frequently asked questions

Is F381E225MMA a tantalum capacitor?

Yes — it is a molded tantalum capacitor from the KYOCERA AVX F38 series.

Can F381E225MMA be used as a replacement for F381E225MMC?

The F381E225MMC is a different size code within the same F38 series. Verify the case size and ESR rating of the MMC variant before substituting — the MMA (size code M) is a 0603 package; the MMC may differ in footprint and electrical specs.
