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).
