T1
RLOAD
1μF X7R multilayer ceramic capacitor, voltage rating to be a minimum of 3 times the output voltage of the DC/DC converter
10μF tantalum capacitor, voltage rating to be a minimum of 1.5 times the output voltage of the DC/DC converter with an ESR of less
than 100mΩ at 100 kHz
100nF multilayer ceramic capacit or, general purpose
450Ω resistor, carbon ?lm, +/-1% tolerance
50Ω BNC termination
3T of the coax cable through a ferrite toroid
Resistive load to the maximum power rating of the DC/DC converter. Connections should be made via twisted wires
Measured values are multiplied by 10 to obtain the speci?ed values.
