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

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.

Specifications

Applications

• Surge protection for mains-connected power supplies and AC/DC converters.
• Protection of semiconductor devices, diodes, ICs, triacs and relays from transient spikes.
• Transient suppression in communication and measurement equipment.
• Input protection for industrial controllers, motor drivers and consumer appliances.

Package Contents

• 1x Metal Oxide Varistor 470V 2.5kA DISC 10mm 10D471K.
