relay for commercial applications. Its low profile height (.280") and .100" grid
spaced terminals, which preclude the need for spreader pads, make it an ideal
choice where extreme packaging density and/or close PC board spacing are
required.

The basic operating concept and internal structure are similar to Teledyne’s
DPDT 114 Centigrid
®
relay. 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 172 relay has an internal discrete silicon diode for coil transient
suppression.
By virtue of its inherently low intercontact capacitance and contact circuit
losses, the 172 relay is an excellent subminiature RF switch for frequencies
well into the UHF spectrum (see Figure 1). Applications include
telecommunications, test instruments, mobile communications, attenuators,
and automatic test equipment.
