Surface Mount CapGuardTM Varistor/Capacitor Combination for EMI/Surge Suppression AVX’s surface mount CapGuardTM products are designed to provide both transient voltage protection and EMI/RFI suppression for electronic circuits. CapGuards are ideally suited to filter out EMI/RFI noise generated by switch mode power supplies or motors on DC lines or I/O lines in electronic circuits. With multilayer varistor (MLV) utilized in CapGuard product, effective transient voltage protection is achieved to protect sensitive electronics from high voltage transients. The capacitor, on the other hand, absorbs high frequency noise on the line. The MLCC capacitors are designed with temperature stable X7R dielectric, allowing for wide temperature use with good capacitance stability. The surface mount CapGuards are characterized with a very small form factor to minimize board space. The parts are assembled using high melting point solder (268ºC solidus / 290ºC liquidus) allowing for standard reflow processing during board level assembly without a risk of reflowing HMP solder.
