MODEL SELECTION TABLES

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 voltage is referenced to -Vin.

7. Operating Ambient Temperature:

Converters can meet the railway T2 and TX temperature requirements.

T2: -40°C to +70°C for all models, TX: -40°C to +85°C with power derating to 55% output power.

8. The LANCUW8 series can meet EN55022 and EN55011 Class A with an external capacitor on the input pins to the converter.

Recommended: 24Vin Models: 1µF/50V 1210 MLCC

48Vin Models: 0.47µF/100V 1812 MLCC

110Vin Models: 1µF/250V*2pcs 1812 MLCC

9. An external input filter capacitor is required if the module has to meet EN61000-4-4, EN61000-4-5.

Recommended: 24Vin & 48Vin Models: Nippon chemi-con KY series, 220µF/100V

110Vin Models: Nippon chemi-con KXJ series, 150µF/200V

10.For surface mount (SMT) type add the suffix “S” to the model number. Ex: LANC2405UW8S.

11.CAUTION: This power module is not internally fused. An input line fuse must always be used.
