Metal Oxide Varistor 470V 2.5kA DISC 10mm 10D471K
4,00 EGP
Description
Features
- Nominal varistor voltage suitable for 470V class transient protection applications.
- High surge capability rated for 2.5kA (8/20µs) peak current to absorb large transient events.
- Additional high-energy tolerance for longer pulse durations (10/1000µs class ratings).
- Compact 10mm disc footprint for space-constrained PCB layouts.
- Low-profile construction with robust dielectric and high insulation resistance to reduce arcing risk.
