Key benefits Protects electronic circuits from transient voltage spikes and surges by clamping excess voltage, reducing risk of component damage and downtime. Wide range of physical sizes and model options lets you choose the varistor that matches the footprint and electrical requirements of your device. 470V rating provides a consistent voltage handling reference across the offered models, simplifying selection for systems designed around that rating. Supplied in practical quantities for repairs and small production runs. What this product does Function: metal-oxide varistors (MOVs) that limit voltage surges by changing resistance under overvoltage conditions. Performance attribute: rated at 470V. Compatibility: available in multiple package sizes (05D, 07D, 10D, 14D, 20D) and a variety of model codes to suit different circuit designs and mounting needs. Available sizes and model codes Package sizes: 05D, 07D, 10D, 14D, 20D. Models listed: 07D220K, 07D391K, 7D431K, 10D471K, 10D101K, 10D330K, 14D471K, 14D220K, 20D431K, 20D471K. Pack information: sold as 20 pieces. One specific option available is the 10D431K model offered in a 20-piece pack. Why customers choose these varistors Flexibility: multiple sizes and model codes cover a range of board layouts and nominal clamping characteristics. Convenience: 20-piece supply supports maintenance, prototyping, and small-batch manufacturing without frequent reordering. Consistency: common 470V rating across the selection simplifies system-level planning where that voltage specification is required. Typical use scenarios Power supply surge protection: install on AC/DC input lines or across transformer secondary rails to protect power supplies and downstream electronics from transient spikes. Control and motor electronics: fit into motor drive or control boards to absorb inductive kickback and transient overvoltages generated by switching loads. Consumer and industrial equipment repair: replace damaged MOVs on PCBs or use stocked packs for field service of appliances, instrumentation, and control panels. Ordering and selection tips Choose the package size (05D–20D) that fits your PCB footprint and clearance requirements. Match the model code to the nominal varistor characteristic required by your circuit. For replacements or service stocking, the 20-piece packs provide a convenient quantity for repeated use.
