2. Maximum value at normal input voltage.

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 voltage is referenced to -Input.

7. Heat sink is optional and P/N: 7G-0020C-F

8. The LWB30 series can meet EN55022 Class A with parallel an external capacitor to the input pins. Recommend: 24 Vin : 4.7 μ F/50V X7R 1812 MLCC 48 Vin : 2.2 μ F/100V X7R 1812 MLCC.

9. An external input filter capacitor is required if the module has to meet EN61000-4-4. EN61000-4-5. The filter capacitor Polytron Devices suggest: 24Vin Nippon chemi-con KY series, 330μ F/50V, ESR55mΩ 48Vin Nippon chemi-con KY series, 220μ F/100V, ESR48mΩ
