DESCRIPTION

The sensitive 136C Centigrid® relay is an ultraminiature, hermetically

sealed, armature relay capable of being directly driven by most IC logic

families. Its .100” grid spaced terminals, which preclude the need for

spreader pads, make it ideal for applications where extreme packaging

density and/or close PC board spacing are required.

The basic concept and internal mechanical structure are similar to the 134

DPDT relay. The following unique construction features and manufacturing

techniques provide overall high reliability and excellent resistance to

environmental extremes:

The 136C feature:

• All welded construction.

• Advanced cleaning techniques provide maximum assurance of internal

cleanliness.

• Unique uni-frame design providing high magnetic efficiency and

mechanical rigidity.

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

• Precious metal alloy contact material with gold plating assures excellent

high current and dry circuit switching capabilities.

• Low operating power

By virtue of its inherently low intercontact capacitance and contact circuit

losses, the 136C relay has proven to be an excellent ultraminiature RF

switch for frequency ranges well into the UHF spectrum. A typical RF

application for this Centigrid® relay is in handheld radio transceivers,

wherein the combined features of good RF performance, small size, low

coil power dissipation and high reliability make it a preferred method of

Transmit-Receive switching.

The Series 136C utilizes an internal silicon diode for coil suppression,

a Zener diode to protect the MOSFET gate input, and an N-channel

enhancement mode MOSFET chip, which enables direct relay interfacing

with most Microprocessor and IC logic families (CMOS, TTL and MOS).
