Series 412 DPDT Non-Latching Established Reliability / Military Relay TO-5 RELAYS ESTABLISHED RELIABILITY MILITARY DPDT SERIES RELAY TYPE 412 DPDT basic relay 412D DPDT relay with internal diode for coil transient suppression 412DD DPDT relay with polarity reversal protection and coil transient suppression diode 412TN DPDT relay with internal transistor driver and coil transient suppression diode Advanced cleaning techniques provide maximum assurance of internal DESCRIPTION cleanliness. The TO-5 relay, originally conceived and developed by Teledyne, has Precious metal alloy contact material with gold plating assures excellent become one of the industry standards for low-level switching from dry circuit high current and dry circuit switching capabilities. to 1 ampere. Designed expressly for high-density PC board mounting, its small size and low coil power dissipation make the 412 relay one of the most The Series 412D and 412DD relays have internal discrete silicon diodes versatile ultraminiature relays available. for coil suppression and polarity reversal protection. The hybrid 412T relay features an internal silicon suppression diode and transistor driver. This The following unique construction features and manufacturing techniques hybrid package reduces required PC board floor space by reducing the provide excellent resistance to environmental extremes and overall high number of external components needed to drive the relay. reliability. By virtue of its inherently low intercontact capacitance and contact circuit The 412 feature: losses, the 412 relay has proven to be an excellent ultraminiature RF switch for frequency ranges well into the UHF spectrum. A typical RF All welded construction. application for the TO-5 relay is in handheld radio transceivers, wherein Unique uni-frame design providing high magnetic efficiency and the combined features of good RF performance, small size, low coil power mechanical rigidity. dissipation and high reliability make it a preferred method of T-R switching High force/mass ratios for resistance to shock and vibration.
