2 / 4 page Model Selection Guide Notes: 1. Load regulation is measured for an output change of 20% 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. For noise sensitive applications, the use of 0.47 μF capacitors will reduce the output ripple. 3. Operation at no-load will not damage these units. However, they may not meet all specifications. 4. The converter should be connected to a low ac-impedance source. An input source with a highly inductive impedance may affect the stability of the converter. In applications where the converter output loading is high and input power is sup- plied over long lines, it may be necessary to use a capacitor on the input to insure start-up. In this case, it is recommended that a low ESR (ESR <1.0 Ω at 100 kHz) capacitor be mounted close to the converter. For 5V input units a 2.2 μF is recommended, for 12V input units, a 1.0 μF, and for 24V input units, a 0.47 μF. 5. It is recommended that a fuse be used on the input of a power supply for protection. See the table above for the correct rating.
