Notes
Notes
1. Minimum load required to meet noise and ripple and initial set accuracy
specifications. Below 25% load, noise and ripple increases to 200 mV pk-pk
typical and load regulation to ±1% max.
2. Cross regulation is ±5% when one output is at 100% the other is varied
between 25% and 100%.
3. For optional 3000 VDC isolation, add suffix ‘-H’ to end of part number.
4. For optional metal case version, add suffix ‘-M’ to end of part number,
eg. JCB0324S12-HM
5. For alternative pin out, add suffix ‘-Z’ to end of part number,eg. JCB0324S12-HMZ
6. Input current measured at nominal input voltage
7. A 220 µF/100 V capacitor across the input is required in order to meet
EN61000-4-4 & EN61000-4-5.
1. All dimensions are in inches (mm)
2. Weight: 0.04 lbs (20 g) approx.
3. Pin diameter: 0.02±0.002 (0.5±0.05)
4. Pin pitch tolerance: ±0.014 (±0.35)
5. Case tolerance: ±0.02 (±0.5)
