9814 & 9852 Series Surface Mount Reed Relays
Ideally suited to the needs of Automated Test Equipment, Instrumentation and
Telecommunications requirements, Coto’s 9814 & 9852 Series is a miniature Surface
Mount Reed Relay that combines small size with exceptional RF performance. e
9814 extends life at ATE loads 3X or more utilizing Coto’s proprietary switch technol-
ogy. e external Magnetic Shield reduces interaction between parts in high density
boards. e 9852 adds Form C capability. Small size plus added features allow for high
density packing, and make these relays ideal for designs such as high speed, high pin
count VLSI testers where high speed, small size and high performance are all needed.
