SMD 0603 Surface Mount Varistor SV0603N300G0A For Notebook Cellular Phone PDA
0603 Surface Mount Varistor SV0603N300G0A Excellent Low And Stable Leakage Current
Surface Mount Varistor DATASHEET: SV0603N300G0A_v89.1.pdf
Description:
The Surface Mount Varistor SV0603N300G0A 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 SV0603N300G0A 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.
