RF Coax Connectors
SMC Connectors
Product Facts
â Three-piece designs
â Fast, clean cable assembly
â Connector bodies
preassembled
â Solderless termination â
no danger of heat damage
â Center conductor and braid
terminated with same tool
â Low noise level
â Miniature screw-on coupling
â TEFLON dielectric
The SMC Connector is
miniature and light-weight,
especially designed for
use in critical applications
where limited space and
vibration are of major
concern.
This connector is designed
in accordance with the
requirements of Specification
MIL-C-39012, Class II,
Category B to assure
the highest standards of
electrical and mechanical
performance. It has a con-
stant impedance of 50 ohms,
a voltage rating of 350 volts
and provides excellent
operation at frequencies
up to 10 GHz. It also has a
threaded coupling and can
be used with a wide range
of miniature coaxial cable
sizes including RG 174,
197, 187, 188 and 316.
