DESCRIPTION
The 114 series Centigrid® Relay is an ultraminiature, hermetically sealed, armature relay. Its
low profile height (.275") and .100" grid spaced terminals, which precludes the need for
spreader pads, make it ideal for applications where extreme packaging density and/or close
PC board spacing are required.

The basic design and internal construction are similar to the Teledyne standard DPDT TO-5
relay (412 Series). The following 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.
The 114D and 114DD Series utilizes internal discrete silicon diodes for coil suppression and
polarity reversal protection.

By virtue of its inherently low intercontact capacitance and contact circuit losses, the 114
relay has shown itself to be an excellent ultraminiature RF switch for frequency ranges well
into the UHF spectrum. A typical RF application for the 114 relay is in hand held 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).

SPACER PAD
NOTES:
Relays can be supplied with a spacer pad attached to the relay header.
The pad M4 permits the relay to be spaced away from the mounting
surface facilitating solder joint inspection. To order add M4 to Part
Number. Example: 114M4-26.
1. Material: Polyester film.
2. Add 0.01 ohm to contact
resistance with mounting pad.

Relays contacts will exhibit no chatter in excess of 10 µsec or transfer in excess of 1 µsec.
“Typical” characteristics are based on available data and are best estimates. No on-going verification tests are performed.
For reference only. Coil resistance not directly measurable at relays terminals due to internal series semiconductor. 114DD only.
Screened HI-REL versions available. Contact factory.
Unless otherwise specified, relays will be supplied with leads as follows: Length will be standard 0.75” (19.05) minimum and will be either
gold plated or solder coated. Contact your local representative for ordering information.
