DPDT relay with internal diode for coil transient suppression

INTERNAL CONSTRUCTION

DESCRIPTION

The 172 Centigrid^®relay is an ultraminiature, hermetically sealed, armature

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.

CONTACT

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.

ENVIRONMENTAL AND

PHYSICAL SPECIFICATIONS

The Series 172 relay has an internal discrete silicon diode for coil transient

suppression.

Vibration

(General Note 1)

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.
