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. Voltage accuracy for the negative output on Dual output models is typically ±3% with a max of ±5%. 3. Maximum ouput noise for dual output units is 150 mV P-P. 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 single output units and from each output to common for dual output units. 4. The optional metal package is nickel plated steel. The dimensions of the metal package are 1.25 x 0.80 x 0.39 Inches (31.8 x 20.3 x 10.0 mm). 5. 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. 6. 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: Vin: 10 µF - 47 µF Vout: 10 µF/100 mA For applications requiring very low output noise levels, a simple LC filter should be effective. 7. The maximum load capacitance is: Mechanical Dimensions Vout Maximum Load Capacitance 3.3 VDC 5 VDC 12 VDC 15 VDC 2,200 µF 1,000 µF 470 µF 330 µF Vout Maximum Load Capacitance ±5 VDC ±12 VDC ±15 VDC 2,200 µF 1,000 µF 470 µF 8. 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.
