KOA Speer Electronics has introduced the NV73S series multilayer type metal oxide varistor that handles a surge current of up to 6,000 A, which is five times higher than existing products. The multilayer construction can absorb a large surge despite its small size. The two-way symmetries can absorb positive and negative surges. The NV73S replaces the NV732E (1210) through 2L (2220) due to its improved surge protection.
Maximum peak current and sizes for the new NV73S are 400 A to 800 A (1210), 500 A to 1,200 A (1812), and

The new NV73S series metal oxide varistor offers protection from ESD (electrostatic discharge) and EMI (electromagnetic interference) for electronic devices. It also provides surge protection for motors, relays and solenoid valves.
The NV73S varistor series meets EU-RoHS requirements. Lead time is 10 weeks. Samples are available upon request.
