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.
