CUI Inc. EMC-05B AC Power Line Filter
The CUI Inc. EMC-05B series AC Power Line Filter is designed to reduce electromagnetic emissions, helping products comply with CISPR22 / EN 55022 Class B standards. It provides protection against surge events and Electrical Fast Transients (EFT). With a wide input voltage range and a rated current of 0.5 A, this filter is suitable for operation in demanding environments with a temperature range of -40 to +85C. Available in board and chassis mount options, it is constructed with a black flame-retardant heat-proof epoxy resin (UL94-V0) case material.
