9300-9400 Series/Surface Mount Reed Relays
Surface Mount Reed Relays
Ideally suited to the needs of Automated Test Equipment, Instrumen-
tation and Telecommunications requirements, Coto’s 9300 and 9400
Series specification tables allow you to select the appropriate relay for
your particular application. If your requirements differ, please consult
your local representative or Coto’s Factory to discuss a custom design.
Series Features
High Insulation Resistance - 1012 Ω minimum (1013 Ω Typical)
High reliability, hermetically sealed contacts for long life
Molded thermoset body on integral lead frame design

9300-9400 Series/Surface Mount Reed Relays
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:
1Consult factory for life expectancy at other switching loads.
2Surface mount component processing temperature:
500°F / 260°C max for 1 minute dwell time. Temperature
measured on leads where lead exits molded package.
3Higher dielectric strength available, consult factory.
4Consists of 56V Zener diode and 1N4148 diode in series,
connected in parallel with coil.
