MTJ Single-Port Modular Jacks

Adam Tech MTJ Single-Port Modular Jacks feature a series of PCB and wire-leaded jacks for industry-standard telephone plugs. The MTJ series offers various jack sizes, including 4P2C to 10P10C. The jacks provide single, ganged, and stacked versions with magnetic or ferrite-filtering options. Adam Tech MTJ Single-Port Modular Jacks have unshielded or metal-shielded options and are available for thru-hole or SMT mounting. The MTJ jacks are UL-approved and meet all required FCC compliances, including No. 47 CFR part 68. The jacks are ideal for Adam Tech modular plugs and telephone plugs.
