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 proper-
ties. 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)
