## **9900 SERIES/SURFACE MOUNT 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 makes these relays ideal for designs in high speed, high pin count VLSI testers where speed, size and performance are all needed.
## **9900 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 - 10[12 ] Ω minimum
- u Coaxial shield for 50Ω impedance
- u 6.5 GHz bandwidth for RF and Pulse switching (fast rise time pulses) [9903 only] u External Magnetic Shield
- u RoHS compliant
