ESD & EMI Filter Protection

Semtech offers ESD / EMI filter protection with low pass L-C and R-C filter devices that use integrated TVS diodes. Our products replace multiple discrete EMI and RFI filter components and are available in small multiline packages. Our EClamp™ devices are designed to suppress unwanted EMI-RFI signals and provide electrostatic discharge and electromagnetic interference protection in portable electronic equipment.
