9800 Series/Surface Mount Reed Relays

SURFACE MOUNT REED RELAYS

Ideally suited to the needs of Automated Test Equipment, Instrumenta-

tion and Telecommunications 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.

Environmental Ratings

Storage Temp:

35°C to

100°C; Operating Temp:

20°C to

85°C

The operate and release voltage and the coil resistance are

specified at 25°C. These values vary by approximately 0.4%/°C

as the ambient temperature varies.

Vibration: 20 G’s to 2000 Hz; Shock: 50 G’s

Notes:

Consult factory for life expectancy at other

switching loads. Contact resistance 2.0Ω defines

end of life.

Surface mount component processing tempera-

ture: 438°F(226°C) max for 1 minute dwell time.

Temperature measured on leads where lead exits

molded package.

Consists of 20V Zener-diode and 1N1002 diode

in series, connected in parallel with coil.
