Metal Oxide Varistor 470V 2.5kA DISC 10mm 10D471K

From the shop's description

Metal Oxide Varistor 470V 2.5kA DISC 10mm 10D471K The Metal Oxide Varistor 470V 2.5kA DISC 10mm 10D471K is a 10mm disc zinc-oxide (ZOV) varistor engineered for transient over-voltage suppression and surge energy absorption in electronic and power systems. It provides a nominal varistor voltage around 470V and a low clamping voltage under high-energy 8/20µs surge pulses, delivering reliable protection for semiconductors, power supplies, industrial controls and consumer electronics while occupying minimal board area. 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.
