NOTES
1. BELLCORE TR-NWT-000332. Case 1: 50% Stress, Temperature at 40°C.
MIL-HDBK-217F Notice2 @Ta=25°C, Full load (Ground, Benign, controlled environment).
2. Maximum value at nominal input voltage and full load.
3. Typical value at nominal input voltage and no load.
4. Typical value at nominal input voltage and full load.
5. Test by minimum Vin and constant resistive load.
6. The on/off control pin is referenced to –Vin.
To order positive logic remote on/off, add the suffix “P” to the model number (Ex: JRW24S15-660P).
To order negative logic remote on/off, add the suffix “R” to the model number (Ex: JRW24S15-660R).
7. “I” type models are more efficient; therefore, they can be operated over a more extensive temperature range than the standard version.
To order extended operating temperature range, add the suffix “-I” to the model number (Ex: JRW24S15-660-I).
8. Heatsink is optional and P/N: 7G-0020C-F.
9. The JRW series can meet EN55022 Class A with external capacitors in parallel connected to the input pins.
Recommended: 24Vin: 2.2µF/50V 1812 MLCC
48Vin: 1.5µF/100V 1812 MLCC
10. An external input filter capacitor is required if the module has to meet EN61000-4-4, EN61000-4-5. The filter capacitor suggested is
Nippon chemi-con KY series, 220μF /100V, ESR 48mΩ.
CAUTION: This power module is not internally fused. An input line fuse must always be used.
*Due to advances in technology, specifications subject to change without notice.
