Exceeding the input range by a significant margin may damage the units. For 24V input the input voltage should not exceed 40V; for 48V models it should not exceed 80V. 2. When measuring output ripple, it is recommended that an external 0.33 F ceramic capacitor be placed from the +Vout pin to the -Vout pin for single output units and from each output to common for dual output units. 3. The optional metal package is nickel plated steel. Dimensions are 1.25 x 0.80 x 0.39 Inches (31.8 x 20.3 x 10.0 mm). 4. These units should not be operated with a load under the specified minimum. Operation at no-load will increase ripple significantly and may cause damage to the unit. 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. Recommended capacitor values are: Derating Curve Vin (VDC) Input Capacitor Sing 10 F Dual 10 ~ 47 F Sing 10 F Dual 10 ~ 47 F Vout (VDC) Output Capacitor 0 to +70C (Electrolytic) -40 to +85C (Tantalum) Mechanical Dimensions 24 48 3.3 5 12 15 100 F 100 F 100 F 100 F 47 F 47 F 47 F 47 F For applications requiring very low output noise levels, a simple LC filter should be effective. 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.
