CRR03-1AS

**MEDER electronic** 

**CRR Series** 

## SPST Reed Relays 

## **DESCRIPTION** 

The MEDER CRR Reed Relay Series is a low-profile device made with a ceramic case that exactly matches the thermal coefficient of expansion of the Reed Switch glass and the reed lead to eliminate any potential packaging stress.  This Reed Relay is the smallest in the industry and switches into the billions of operations. 

## **FEATURES** 

This Relay has 1 µ V typical thermal offset. Measuring only 8.6 mm x 4.4 mm x 3.4 mm, the leadless design eliminates skewing of leads and coplanarity issues. Insulation resistance typical to all points is >10[14 ] Ohms. 

- Ceramic / thermoset molded package 

- Patent pending 

- Smallest in the industry 

- No lead frame surface mount design eliminates skewing of leads and coplanarity issues 

- Available with BGA 

## **APPLICATIONS** 

   - Internal magnetic shield standard 

   - Very low profile 

   - Gold plated leads 

- Test and measurement 

- Medical equipment 

- Telecommunications 

- Low thermal offset typical 1 µV 

- TCE matching of all internal components 

- Insulation resistance typical 1014 ohms 

- 3 Volt option available
