NOTES
1. BELLCORE TR-NWT-000332. Case 1: 50% Stress, Temperature at 40ºC.
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 input and constant resistive load.
6. Trimming allows the user to increase or decrease the output voltage set point of the module. This is accomplished by connecting an
external resistor between the TRIM pin and either the +OUTPUT pin or the –OUTPUT pin.
7. The CTRL pin voltage is referenced to -INPUT. (See the “Product Options” table on page 5 for suffix options).
8. The power module can operate in a variety of thermal environments; however, sufficient cooling should be provided to help ensure
reliable operation.
9. The JF Series meets EN55022 Class A and Class B only with external components connected to the input pins of the converter.
10. An external filter capacitor is required if the module has to meet EN61000-4-4 and EN61000-4-5. The filter capacitor suggested is
Nippon chemi-con KY Series, 220μF/100V, ESR 48mΩ.
CAUTION: These power modules are not internally fused. An input line fuse must always be used.
OUTPUT ADJUSTABILITY
Output voltage adjustment allows the user to increase or decrease the output voltage set point of a module. This is accomplished by
connecting an external resistor between the TRIM pin and either the +OUTPUT or -OUTPUT pins. With an external resistor between the
TRIM and -OUTPUT pin, the output voltage set point increases. With an external resistor between the TRIM and +OUTPUT pin, the
output voltage set point decreases. The external TRIM resistor needs to be at least 1/16W.
