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 RGUW3 series meets EN55022 Class A and input reflected ripple current with an external L-C filter before the input pins to the
converter. (See Class B figure for connecting network)
Recommended: 12Vin: C1=4.7µF/25V 1812 MLCC C3=220pF/3KV 1808 MLCC L1=10µH 0504 SMD Inductor P/N: PMT-047
24Vin: C1=4.7µF/50V 1812 MLCC C3=220pF/3KV 1808 MLCC L1=12µH 0504 SMD Inductor P/N: PMT-062
48Vin: C1=4.7µF/100V 1812 MLCC C3=220pF/3KV 1808 MLCC L1=10µH 0504 SMD Inductor P/N: PMT-047
7. 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.
8. To order surface mount version, add the suffix “S” to the model number (Ex: RG24S5UW3S).
9. To order 3000VDC I/O isolation version, add the suffix “H” to the model number (Ex: RG24S5UW3H).
10. 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.
