412H-18 Description

Short technical summary and product information.

The Teledyne 412H-18 is a high-performance, high-temperature TO-5 relay. Originally conceived by Teledyne, this relay is designed for reliable operation in ambient temperatures up to 200°C. Special material selection and processing ensure freedom from contact contamination and mechanical malfunctioning in extreme heat.

 

This DPDT relay is suitable for high-density PC board mounting and offers versatility due to its small size and low coil power dissipation. Its inherent low intercontact capacitance and contact circuit losses make it an excellent ultraminiature RF switch for applications in the UHF spectrum.

 

Typical applications include down-hole instrumentation in oil exploration and high-temperature industrial and process control instrumentation. The relay is built with a robust construction to withstand demanding environmental conditions.

 

The 412H-18 is designed for through-hole mounting. Its specifications include resistance to vibration up to 30 g's and shock up to 75 g's.
