Notes & safety
Notes: 1. MTBF: BELLCORE TR-NWT-000332. Case 1: 50% Stress, Temperature at 40°C (Ground fixed and controlled environment). MIL-STD-217F Notice2 @Ta=25°C, Full load (Ground, Benign, controlled environment).
2. The ON/OFF control pin voltage is referenced to -Vin. To order negative logic ON/OFF control add the suffix "R" (Ex: CB48S5-6000R)
3. Heat sink is optional, consult factory for ordering details.
4. The CB series can meet EN55022 Class A with an external capacitor in parallel with the input pins. Recommended: For 12Vin: 10µF/25V X7R 1812 MLCC. For 24Vin: 4.7µF/50V X7R 1812 MLCC. For 48Vin: 2.2µF/100V X7R 1812 MLCC.
5. An external filter capacitor is required if the module has to meet EN61000-4-4, EN61000-4-5. The filter capacitor suggested: 12Vin & 24Vin Nippon chemi-con KY series, 330µF/50V, ESR 55MΩ. For 48Vin Nippon chemi-con KY series, 220µF/100V, ESR 48MΩ.
Due to advances in technology, specifications are subject to change without notice.
