COTO TECHNOLOGY

9400-9800 Series/Surface Mount Reed Relays

Top View:

Dot stamped on top of relay refers to pin #1 location

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:

430°F(221°C) max for 1 minute dwell time. Tempera

ture measured on leads where lead exits molded package.
