Teledyne Through Hole RF Relay, 12V DC Coil, DPDT, Gold Plated, Model 172-12

The Teledyne 172-12 is an ultra-miniature RF relay designed for demanding signal-switching applications in electronics, telecommunications, mobile communications, test instruments, and attenuators. Featuring a through hole mount and a 12V DC coil, this relay offers superior switching performance and reliability for PCB layouts requiring tight spacing and hermetic sealing.

Its DPDT (double pole double throw) contact configuration provides versatile switching capabilities essential for modern RF circuits. The relay’s precious metal alloy contacts are gold plated, delivering high current handling and dry circuit switching for critical signal paths. Thanks to an internal discrete silicon diode, coil transient suppression is robust, enhancing lifetime and performance consistency.

Performance features include a low profile height and grid-spaced terminals to eliminate the need for spreader pads, ideal for close PCB mounting. The advanced cleaning techniques applied during manufacture ensure maximum assurance of internal cleanliness, which is vital for consistent switching in RF environments.

This relay delivers outstanding electrical characteristics: coil resistance of 400 ohms, maximum DC voltage rating of 16V, contact resistance of only 150 milliohms, and coil power of 360 mW. Its low insertion loss, 0.4pF isolation and intercontact capacitance, and welded construction allow reliable, high-efficiency operation from DC to 2GHz. The relay’s unique uni-frame design provides high magnetic efficiency and mechanical rigidity, making it highly resistant to heavy shock and vibration in industrial, laboratory, and commercial installations.

The Teledyne 172-12 RF relay is compliant with RoHS and features approvals including ANSI/ESD S20.20:2014 and BS EN 61340-5-1:2007. Its wide operating temperature range, from -55°C to 85°C, assures stability in harsh environments. The device measures just 8.51mm in length and 7.11mm in height, perfectly suited for densely populated electronic boards.

Industrial use cases include signal switching and isolation in high-frequency applications, telecommunication networks, mobile base stations, RF test instrumentation, and precision electronic controls. It is renowned for its reliability in both commercial and laboratory environments.
