The MHRJJ66NFRA RJ12 modular jack is widely used in:
MHRJJ66NFRA is a single-port RJ12 modular jack (6P6C) with a right-angle, through-hole PCB mount. It is designed for telecom, control, and low-speed signal applications.
MHRJJ66NFRA is classified as an RJ12 connector (6P6C). It can physically accept RJ11 plugs, but all six positions are supported.
No. MHRJJ66NFRA does not include integrated magnetics, making it unsuitable for Ethernet PHY designs that require magnetic isolation.
No. This model is an unshielded modular jack. Shielded versions are available in the same product family for EMI-sensitive applications.
It features a through-hole (THT) right-angle mounting, ideal for wave soldering and mechanically robust PCB designs.
No. This connector is supplied without LEDs or light pipes.
