Surface Mount Fuse Datasheet

422A Series

AEC-Q200 Qualiﬁed > Ceramic Fuse

RoHS Pb

Description

The 422A is a 250V rated Wire-in-Air Surface Mount, AEC-

Qualified fuse. They are specifically tested to cater to secondary

circuit protection needs of compact auto electronics applications.

The wire-in-air design of the 422A Series results in a relatively high

I²t in a 2410 size.

The general design ensures excellent temperature stability and

performance reliability.

Notes

1. AC Interrupting Rating tested at rated voltage with unity power factor. DC Interrupting Rating tested with time constant <0.8 ms for 32 VDC, <2.2 ms for 86 VDC, <0.22 ms for 125 VDC, and <0.1 ms for 250 VDC.

2. Nominal Resistance measured with <10% rated current.

3. Nominal Melting I²t measured at 1 msec. opening time.

4. Interrupting Rating may differ based on Agency Approval. See Agency Approval certiﬁcate for more details.

Speciﬁcations are subject to change without notice.
