MIL-HDBK-217F Notice2 @Ta=25 ºC, 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. An external input filter capacitor is required if the module has to meet EN61000-4-4, EN61000-4-5. 7. The output requires a minimum loading on the output to maintain specified regulation. Operation under no-load condition will not damage these devices, however they may not meet all listed specification. http://www.microdc.cn Technical Enquiries-Email:[email protected] Tel:0086-20-86000646 Page 2 of 3 WRA-YHD-3W&WRB-YHD-3W Series DERATING GRAPH MECHANICAL DIMENSIONS DIP PIN CONNECTION PIN SINGLE DUAL PIN SINGLE DUAL 1 + INPUT + INPUT 24 + INPUT + INPUT 2 NC - OUTPUT 23 NC - OUTPUT 3 NC COMMON 22 NC COMMON 10 -OUTPUT COMMON 15 -OUTPUT COMMON 11 +OUTPUT +OUTPUT 14 +OUTPUT +OUTPUT 12 - INPUT - INPUT 13 - INPUT - INPUT RoHS COMPLIANT INFORMATION This series is compatible with RoHS soldering systems with a peak wave solder temperature of 300°C for 10 seconds.
