Multilayer Varistor DATASHEET: SV0402E180G2B_v89.1.pdf
Description:
The Multilayer Varistor SV0402E180G2B is based on Multilayer fabrication technology. These components are designed to suppress a variety of transient events, including those specified in IEC 61000-4-2 or other standards used for Electromagnetic Compliance (EMC). The SV0402E9R0G0B is typically applied to protect integrated circuits and other components at the circuit board level. It can operate over a wider temperature range than zener diodes.
