Notes
1. Maximum power with 18 CFM forced air is 250 W, or 200 W with convection cooling.
2. Ripple and noise measured over 15 MHz bandwidth with a 0.47 µF capacitor.
3. For non current share option delete suffix ‘C’ from model number.
4. All models require 2 A minimum load on V1. On V2, JPS250PQ46 requires 1 A and JPS250PQ41 requires 0.5 A.
