When measuring output ripple & noise, it is recommended that an external ceramic capacitor (0.33 µF typ.) be placed from the +VOUT to the -VOUT pins for single output units and from each output to common for dual output models. 2. Free air convection is typically 20 LFM. The units should not be operated in still air (0 LFM). 3. Exceeding the absollute ratings could damage the unit. 4. It is recommended that a fuse be used on the input of a power supply for protection.
