FEATURES
1. High frequency characteristics (Impedance 50Ω, ~1.0GHz)
•Insertion loss; Max. 0.3dB
•Isolation; Min. 20dB (Between open contacts)
Min. 30dB (Between contact sets)
•V.S.W.R.; Max. 1.2
2. Surface mount terminal
This relay is a surface-mounted model with excellent high-frequency properties. In addition, it can use a microstrip
line in the base circuit design which spares the labor of machining the base.
3.Low profile small type
9.7(W)×14.7(L)×5.9(H) mm
.382(W)×.579(L)×.232(H) inch
4.High sensitivity: 140 mW nominal operating power
5.High contact reliability
Electrical life: Min. 107 (10mA 10V DC)
