CW 10W~12W SERIES APPLICATION NOTES: EXTERNAL CAPACITANCE REQUIREMENTS: No external capacitance is required for operation of the CW 10W~12W series. To meet the reflected ripple requirements of the converter, an input impedance of less than 0.5 ohm from DC to 100KHz is required. External output capacitance is not required for operation, however it is recommended that 10uF tantalum and 0.1uF ceramic capacitance be selected for reduced system noise. We can offer EMC-Filter According to EN55011/22 Class A.
