Output load regulation is specified for a load change of 10% to 100%. 2. When measuring output ripple, it is recommended that an external 0.33 µF ceramic capacitor be placed from the +Vout pin to the -Vout pin. 3. The isolation capacitance of model MH124S-24E is 30 pF. 4. Operation at no load will not damage these units, however, they may not meet all specifications. 5. These converters are specified for operation without external components. However, in some applications the addition of input/output capacitors will enhance stability and reduce output ripple. The simple connection shown at right will typically meet EN 55022 Class B. 6. It is recommended that a fuse be used on the input of a power supply for protection. See the Model Selection table above for the correct rating.
