One million cycle repeatability data is based upon 396 observations with an average repeatability ±0.033 dB and a range of ±0.093 dB. 2. Repeatability of attenuation values were obtained from tests conducted in a 20 dB attenuator network with a 0 dBm input signal. 3. Relay operates at frequencies higher than 3 GHz with reduced RF performance characteristics. 4. Curves were developed from tests performed on a 0.031" copper clad, reinforced PTFE circuit board at 20°C (ref). The unutilized contacts were terminated in 50 ohms; characteristic impedance of measuring equipment is 50 ohms. The relays were mounted flush to the circuit board ground plane without the relay header soldered to the ground plane. ©2003 TELEDYNE RELAYS SPECIFICATIONS ARE SUBJECT TO CHANGE WITHOUT NOTICE www.teledynerelays.com RF300 RF303 Page 28 RF300 RF303/1203/Q1 Contact arrangement 2 Form C (DPDT) Rated duty Continuous Contact resistance 0.15 ohm max. initial (measured 1/8" from the header) Contact load rating Resistive: 1Amp/28Vdc Low level: 10 to 50 µA, 10 to 50 mV Contact life rating 10,000,000 cycles typical at low level RF300: 450 mW typical @ nominal rated voltage RF303: 200 mW typical @ nominal rated voltage Coil operating power Operate time Release time RF300 4.0 ms. max.
