Reed Relays 9300-9400 Series


	Surface Mount Reed Relays Ideally suited to the needs of Automated Test Equipment, Instrumentation 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 u High Insulation Resistance - 10¹²W minimum (10¹³W Typical) u High reliability, hermetically sealed contacts for long life u Molded thermoset body on integral lead frame design u High speed switching compared to electromechanical relays

	9300 Series u Load switching (15 Watts) and high dielectric strength (500 VDC) between contacts u Proven reliable to switch telephone loads (48V, 100mA)


	9400 Series u Small surface mount package (0.225" x 0.550") u Low capacitance (Contact to Shield - 1.1 pF typical) u Coaxial shield for 50 V impedance.Excellent for RF and Fast Rise Time Pulse switching (up to 2.0 GHz)

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.




	Environmental Ratings²Storage 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
