Centigrid® RF Relay - 172, S172 and GRF172D Series


The 172, S172 and GRF172D series of Centigrid® relays are ultra-miniature, hermetically sealed, DPDT armature relays designed to be used in many RF applications. A low profile height and grid spaced terminals - which prevent the need for spreader pads - make them suitable for use when close PCB spacing is required. With a low inter-contact capacitance and contact circuit losses, the 172, S172 and GRF172D series of Centigrid® relays are an excellent ultra-miniature RF switch for frequencies well into the UHF spectrum (see datasheet for performance curves).
The 172 Centigrid® relays are PCB THT (see stock numbers 351-459, 351-465, 351-471, 758-2436, 758-2423, 758-2427), the S172 and GRF172D Centigrid® relays are PCB SMT (see stock numbers 220-863, 220-942 and 758-2473). In addition to the standard types there are the 172D, S172D and GRF172D relays which have an internal discrete silicon diode that provides coil transient suppression.
The GRF172D (stock number 758-2473) features a unique ground shield that isolates and shields each lead to ensure excellent contact-to-contact and pole-to-pole isolation. This ground shield provides a ground interface that results in improved high frequency performance as well as parametric repeatability.
Applications include telecommunications, test instruments, mobile communications, attenuators and many other RF and data switching functions.

Hermetically sealed
Excellent switching performance from d.c. to 2GHz
High resistance to shock and vibration
Gold plated contacts
Low insertion loss - isolation and intercontact capacitance of 0.4pF
Uni-frame design provides high magnetic efficiency and mechanical rigidity
High reliability and excellent resistance to environmental extremes
Both THT and SMT versions of the 172 and S172 series have a profile height of 7.11mm and a pin pitch of 2.54mm. The SMT GRF172D version has a profile height of 8.38mm and a pin pitch of 2.54mm
