9800 Series/Surface Mount Reed Relays

Ideally suited to the needs of Automated T est Equipment, Instrumenta- tion and T elecommunications requirements, Coto’s 9800 Series is an ultra-miniature Surface Mount Reed Relay that combines small size with exceptional RF performance. 9814 extends life at ATE loads 3X or more utilizing Coto’s proprietary switch technology. The external Magnetic Shield reduces interaction between parts in high density boards. 9852 adds a form C capability. Small size plus added features allow for high density packing, and make these relays ideal for designs such as high speed, high pin count VLSI testers where speed, size and performance are all needed.

These values vary by approximately 0.4%/°C as the ambient temperature varies. Vibration: 20 G’s to 2000 Hz; Shock: 50 G’s T op View: Dot stamped on top of relay refers to pin #1 location Notes:

1 Consult factory for life expectancy at other

switching loads. Contact resistance 2.0Ω defines end of life.

2 Surface mount component processing tempera-

ture: 438°F(226°C) max for 1 minute dwell time. T emperature measured on leads where lead exits molded package.
