Twenty pieces of MOV varistors model 14D431K, with a rated voltage around 430V, are included in this pack. Each part is designed to protect electronic circuits from voltage transients by clamping voltage spikes and diverting surge current away from sensitive components. This pack is ideal for replacement, , or bulk procurement for surge protection applications. Key benefits Protects critical electronics from voltage transients and surges, reducing the risk of component damage and system downtime. Fast response to surge events with reliable clamping action to safeguard power supplies and control circuitry. Durable radiallead disk design allows easy PCB mounting and replacement in standard throughhole assemblies. Consistent performance with tight manufacturing tolerance (K = ±10%), suitable for a range of consumer and industrial applications. Economical 20piece pack for bulk projects, service centers, or stocking purposes. Key attributes Functionality: Metal Oxide Varistor (MOV) for surge suppression and transient voltage protection.
