Reed Relays 9900 Series


	Surface Mount Reed Relays Ideally suited to the needs of Automated Test Equipment and Instrumentation requirements, Coto's 9900 Series is the smallest Surface Mount Reed Relay available. The external Magnetic Shield reduces interaction between parts in high density boards. Small size plus the use of Coto's proprietary switch technology make these relays ideal for designs such as high speed, high pin count VLSI testers where speed, size and performance are all needed.

	Series Features u Available in Axial, Gull wing and "J" lead configurations u Tape and Reel packaging available u High reliability, hermetically sealed contacts for long life u High Insulation Resistance - 10¹²W minimum u Coaxial shield for 50 W impedance. u 6.5 GHz bandwidth for RF and Pulse switching (fast rise time pulses) [9903 only] u External Magnetic Shield

	Notes: ¹Consult factory for life expectancy at other switching loads. Contact resistance 2.0W defines end of life. ²Surface mount component processing temperature: 500°F (260°C) max for 1 minute dwell time. Temperature measured on leads where lead exits molded package. ³Consists of 56V Zener diode and 1N4148 diode in series, connected in parallel with coil.


	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 Moisture Sensitivity per J-STD-020B, Level 2
