DESCRIPTION

The S114 Series Surface Mount Centigrid

armature relay. The low profile height (.360”) and .100” lead spacing make it ideal for

applications where extreme packaging density and/or close PC board spacing are required.

The specially formed leads are pre-tinned to make the relays ideal for most types of surface

mount solder reflow processes.

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 S114D and S114DD Series utilize internal discrete silicon diodes for coil suppression

and polarity reversal protection.

By virtue of its inherently low intercontact capacitance and contact circuit losses, the S114

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 S114 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).
