DESCRIPTION

The GRF172 surface-mount Centigrid®relay is an ultraminiature, hermetically

sealed, armature relay for 2.5 GHz RF applications. Its low profile height

(.330") and .100" grid spaced terminals make it an ideal choice where extreme

packaging density and/or close PC board spacing are required.

The GRF172 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. The GRF172

extends performance advantages over similar RF devices that simply offer

formed leads for surface mounting.

Unique construction features and manufacturing techniques provide overall

high reliability and excellent resistance to environmental extremes:

• All welded construction.

•Unique uni-frame design providing high magnetic efficiency and mechanical

rigidity.

•High force/mass ratios for resistance to shock and vibration.

• Advanced cleaning techniques provide maximum assurance of internal

cleanliness.

• Precious metal alloy contact material with gold plating assures excellent

high current and dry circuit switching capabilities.

The Series GRF172D has an internal discrete silicon diode for coil transient

suppression.

Applications include telecommunications, test instruments, mobile

communications, attenuators, and automatic test equipment.
