Teledyne Part # 134D-5B MIL-SPEC DPDT Relay. 8 lead (.75" leads) Coil: 5VDC, (7.5VDC Max) 100 Ohms Contact Rating: 1A at 28VDC / 250mA at 115VAC (Resistive Load) ? 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).
