Vishay introduces a new high performance varistor

Published time: 2019-12-20 09:54:44

Vishay Intertechnology, inc. recently announced the launch of a new series of VDR metal oxide varistors (MOV)- VDRUS series, certified operating temperature up to +125 °C, UL 1449 edition 4 and VDE/IEC 61051-1/2 standards. Vishay BCcomponents VDRUS series resistors are specially designed for over voltage and transient voltage protection in consumer electronics and industrial applications.

The recently introduced device consists of high-purity zno sheet resistors, with standard external dimensions of 7 mm, 10 mm, 14 mm and 20 mm, with two solid copper leads or fog-tin-clad steel wires.Due to the use of ul94-v0 grade flame retardant silicone coating, electrical, mechanical and climate protection capabilities, the new varistors have excellent high temperature performance.


VDRUS series electrical impedance surge current 1.8ka to 13ka, rated voltage 115 VAC to 680 VAC, energy absorption 19 J to 720 J, there are direct lead or bend lead.Piezors are suitable for household appliances such as electric furnaces and washing machines, as well as power supply controllers and input filters in industrial applications such as motor controllers, AC/DC converters and circuit breakers.

The device is RoHS compliant, halogen free, suitable for automatic plug-in assembly, wave soldering and pin dip solder paste reflow soldering.

VDRUS series varistors are available now and in mass production with a lead time of six to eight weeks.

Vishay is one of the world's largest manufacturers of discrete semiconductors (diodes, MOSFETs and infrared optoelectronic components) and passive electronic components (resistors, inductors and capacitors). These components are used in almost all types of electronic devices and devices in the industrial, power, automotive, computer, consumer, telecommunications, military, aerospace, and medical markets. Vishay's product innovations, successful acquisition strategies and “one-stop” services have placed the company among the world's leaders in the industry.
