AVX has extended the voltage and energy ratings of its radial leaded TransGuard Automotive Series with the addition of its new VR20 varistors, expanding both the number and type of applications for which the series is applicable.
Based on patented multilayer varistor (MLV) technology, providing bidirectional transient voltage protection in the on-state and EMI/RFI attenuation in the off-state, these components combine circuit protection and EMI/RFI attenuation functions in a single, high-reliability device, allowing designers to both reduce component count and save critical board space.
Qualified to AEC-Q200, rated for -55°C to +125°C, and featuring a robust construction with conformal epoxy coating, the VR20 series is ideal for use in a variety of harsh automotive and industrial applications, including inductive switching, DC motors, water and fuel pumps, and relays.
The varistors are rated for 25 kV ESD and are available in three working voltages (18 V, 26 V and 48 V), four clamping voltages (42 V, 54 V, 60 V and 100 V) and three energy ratings (0,7 J, 1,2 J and 1,6 J). Lead-free and RoHS-compliant, they feature nickel-tin leads and can be shipped in bulk or packaged on tape and reel. Nickel-free leads are available upon request.
