DC path resistance typically remains low for the life of the relay. At the end of relay life, the
path resistance rises rapidly above 1 Ω. Load ratings apply to relays used within the
specification before the end of relay life.

Thermal EMF

Crosstalk (50 Ω termination, channel-to-channel)

10 kHz

≤-85 dB, typical

100 kHz

≤-70 dB, typical

1 MHz

≤-50 dB, typical

10 MHz

≤-30 dB, typical

Isolation (50 Ω termination, open channel)

10 kHz

≥85 dB, typical

100 kHz

≥65 dB, typical

1 MHz

≥45 dB, typical

10 MHz

Dynamic Characteristics

Maximum cycle speed

145 cycles/s

Relay operate time
