Description
The EClamp 2378K is a low pass filter array with
Bidirectional EMI/RFI filter with integrated TVS
integrated TVS diodes. It is designed to suppress
for ESD protection
unwanted EMI/RFI signals and provide electrostatic
ESD protection to IEC 61000-4-2 (ESD) Level 4,
discharge (ESD) protection in portable electronic
15kV (air), 8kV (contact)
equipment. This state-of-the-art device utilizes solid-
