The VCAS Series MLVs (multilayer varistors) with FLEXITERM technology feature soft terminations that provide up to 0.2 in. (5 mm) of flexure over 3,000 temperature cycles extending up to 302°F (150°C) with zero flex failures and stable electrical characteristics. The AEC-Q200-qualified series also provides high current and energy handling capabilities, bidirectional overvoltage protection, and EMI/RFI attenuation in power and signal lines.
Reliably withstanding severe flexing, vibration, and temperature cycling, the series satisfies automotive industry demands for more robust component solutions. They provide increased reliability and good mechanical and thermomechanical performance. In addition, these MLVs exhibit super-fast response times and multiple ESD strike capabilities. They also provide EMI/RFI attenuation in their off state, which can reduce or even eliminate the need for additional EMC capacitors.
Currently available in four surface-mount cases sizes ranging from 0603 to 1210, the VCAS Series MLVs are rated for five working voltages ranging from 5.6 to 30VDC, five clamping voltages extending from 18 to 67V, four energy transients spanning 0.1 to 1.5J, and operating temperatures as low as -67°F (-55°C) and as high as +302°F (+150°C). They are also RoHS-compliant.
The series is ideal for use in the signal and power lines of automotive, aerospace, and IoT application subject to hazards like significant temperature variations, vibration, wave soldering, forced cooling, improper handling, the insertion and removal of PCBs from connectors, and high-density board configurations.
Typical applications:
- High flexure stress
- Variable temperature applications
- Automotive
