Ideally suited to the needs of Automated Test Equipment, Instrumentation
and Telecommunications requirements, Coto's 9400 Series specification
tables allow you to select the appropriate relay for your particular applica-
tion. The Coto 9800 Series is an ultra-miniature Surface Mount Reed
Relay that combines small size with exceptional RF performance. This
small size allows for high density packing, and is ideal for high speed, high
pin count VLSI testers. Other applications include communications
systems and instrumentation. If your requirements differ, please consult
your local representative or Coto's Factory to discuss a custom design.

Environmental Ratings
2
Storage Temp: -35C to +100C; Operating Temp: -20C to +85C
The operate and release voltage and the coil resistance are
specified at 25C. 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:
1
Consult factory for life expectancy at other switching
loads. Contact resistance 2.0
defines end of life.
2
Surface mount component processing temperature:
430F(221C) max for 1 minute dwell time. Tempera
ture measured on leads where lead exits molded package.
3
Consists of 20V Zener-diode and 1N1002 diode in series,
connected in parallel with coil.
