DESCRIPTION
The 134 sensitive Centigrid
®
relay retains the same features as the 114
standard Centigrid
®
relay with only a minimal increase in profile height (.375
in.). Its .100-inch grid spaced terminals, which preclude the need for spreader
pads, and its low profile make the 134 relay ideal for applications where high
packaging density is important.
The following unique construction features and manufacturing techniques
provide excellent resistance to environmental extremes and overall high
reliability:
• 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 134D and 134DD have internal discrete silicon diodes for coil
suppression and polarity reversal protection.
The sensitive 134 Centigrid
®
relay has a high resistance coil, thus requiring
extremely low operating power (200 mw typical). The advantages of reduced
heat dissipation and power supply demands are a plus.
By virtue of its inherently low intercontact capacitance and contact circuit
losses, the 134 relay has proven to be an excellent ultraminiature RF switch
for frequency ranges well into the UHF spectrum. A typical RF application for
the 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 (see
Figure 1).

2. “Typical” characteristics are based on available data and are best estimates. No on-going
verification tests are performed.
3. Unless otherwise specified, parameters are initial values.
4. For reference only. Coil resistance not directly measurable at relay terminals due to
internal series diode in 134DD only.
5. Unless otherwise specified, relays will be supplied with either gold-plated or solder-
coated leads.
6. The slash and characters appearing after the slash are not marked on the relay.
