New product- Plastic-encapsulated and button type SMD Varistor
April 16, 2022
More and more DOB LED lamps, a large number of plastic-encapsulated chip varistors have been used to replace plug-in and laminated chip varistors. AMPFORT Electronics has shipped in batches, replacing 7D471K and 10D471K for customers, and has passed a number of strict tests with low VC. Both version can replace traditional through-hole metal oxide varistor and easy to be installed in PCB board.
