INTERNAL CONSTRUCTION  
DESCRIPTION  
The S172 Surface Mount Centigrid® relay is an ultraminiature, hermetically sealed, armature  
relay for commercial applications. Its low profile height (.470) and .100” grid spaced  
terminals, which precludes the need for spreader pads, makes it an ideal choice where  
extreme packaging density and/or close PC board spacing are required. The specially  
formed leads are pre-tinned to make the relays ideal for all types of surface mount solder  
reflow processes.

CONTACT  
The basic design and internal structure are similar to the Teledyne DPDT Centigrid® relay  
(114 Series). Unique construction features and manufacturing techniques provide overall  
high reliability and excellent resistance to environmental extremes:

CONTACT  
All welded construction.

CONTACT  
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.  
ENVIRONMENTAL AND  
PHYSICAL SPECIFICATIONS  
The S172 Series utilizes an internal discrete silicon diodes for coil suppression with  
electrical characteristics as specified herein.

By virtue of its inherently low intercontact capacitance and contact circuit losses, the S172  
relay is an excellent subminiature RF switch for frequency ranges well into the UHF  
spectrum (see Figure 1). Applications include telecommunications, test instruments, mobile  
communications, attenuators, and automatic test equipment.
