Specifications and operating details
The following points were extracted from the PDF text. Check the associated conditions, notes and limits in the complete document before using a value in a design.
- DFC25 SERIES SINGLE OUTPUT Up to 30 Watts Output Power Remote ON/OFF Common and Differential Mode Input Filters +3.3, +5V, or +12V Outputs Remote Voltage Sense Efficiencies to 81% Operation from -25°C to 85°C 700/1544V Isolation Two Year W.
- Operation to +70°C ambient with externally supplied forced air cooling, 100LFM. (3) Case is tied to -Input, Pin 1.
- Mechanical tolerances unless otherwise noted: X.XX dimensions: ±0.020 inches X.XXX dimensions: ±0.005 inches General Specifications (1) All Models Units Isolation (3) Isolation Voltage Input to Output 12V, 24V Input MIN 700 Volts48V Input.
- 04/2000 (1) All parameters measured at Tc=25°C, nominal input voltage and full rated load unless otherwise noted. (2) Measurement bandwidth is 0-20 MHz for peak-peak measurements, 10 kHz to 1 MHz for RMS measurements.
- Output noise is measured with a 0.01µF/100V ceramic capacitor in parallel with a 1µF/35V Tantalum capacitor, 1 inch from the output pins to simulate standard PCB decoupling capacitance. (3) Short term stability is specified after a 30 minu.
- To meet the reflected ripple requirements of the converter, an input impedance of less than 0.09 Ohms at 200 kHz is required.
- External output capacitance is not required for operation, however it is recommended that 1µF to 10µF of Tantalum and 0.001 to 0.1µF ceramic capacitance be selected for each output to reduce system noise.

Engineering review checklist
- Check resistance value, tolerance, temperature coefficient and long-term stability over the operating range.
- Derate continuous power for ambient temperature and verify pulse or surge capability separately.
- Match the land pattern, termination finish and current-sense routing to the exact package option.
Always confirm values against the latest manufacturer-controlled datasheet, especially when qualifying a substitute or releasing a production BOM.
