DESCRIPTION
The S114 Series Surface Mount Centigrid^® Relay is an ultraminiature, hermetically sealed,
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.
The basic design and internal construction are identical to the 114 Series Centigrid^® relays,
and are capable of meeting Teledyne Relays T ²R^® requirements. 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 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).
