Inputcan't exceed this value,or Min Nom Max Input Voltage Output The WRA_YMD-5W& WRB_YMD-5W series are specially designed for applications where a group of polar power supplies are isolated from the input power supply in a distributed power supply system on a circuit board. These products apply to: 1) where the voltage of the input power supply is wide range (voltage range ≤2:1); 2) where isolation is necessary between input and output (isolation voltage ≤1500VDC); 3) where the regulation of the output voltage and the output ripple noise are demanded. 4.5 6 9 Notes 9 12 18 18 24 36 36 48 72 Min Nom Max Notes ±1% Vo1 ±3% Vo2 Setpoint Accuracy ±0.2% Line Regulation ±0.5% Load Regulation Dynamic Response Ripple and Noise 3%Vo Pk deviation 50~75% load 200 settling time 50mVp-p 50~25% load Vo 5Vdc 100mVp-p Other Max Notes ±0.02%/℃ Temperature coefficient General Min Isolation Voltage 500Vdc Nom Input-Output Input-Case Output-Case Switching Frequency 82% typ MTBF 10X105h Bellcore ,25℃ -25℃ +85℃ -43℃ +105℃ Storage Temperature -40℃ +125℃ Relative Humidity 10% 90% Case Temperature MICRODC reserves the copyright 300KHZ Efficiency Military *Input voltage can't exceed this value,or will cause the permanent damage. http://www.microdc.cn Technical Enquiries-Email:[email protected] Tel:0086-20-86000646 Page 1 of 2 WRA-YMD-5W＆WRB-YMD-5W Series OUTLINE DIMENSIONS ＆ FOOTPRINT DETAILS RECOMMENDED FOOTPRINT MECHANICAL DIMENSIONS Dual/Single Output RECOMMENDED FOOTPRINT Top view,grid:2.54mm(0.1inch) diameter:1.00mm(0.039inch) TUBE OUTLINE DIMENSIONS Note: Unit:mm[inch] Pin section tolerances:±0.10mm[±0.004inch] General tolerances:±0.25mm[±0.010inch] FOOTPRINT DETAILS Pin Single Dual 1 GND GND 2 Vin Vin 3 +V0 +V0 4 NC 0V 5 0V -V0 Note: Unit :mm[inch] General tolerances: ±0.50mm[±0.020inch] L=530mm[20.866inch] Tube Quantity: 19pcs L=220mm[8.661inch] Tube Quantity: 7pcs When the environment temperature is higher than 71 71°°C, the product output ower should be less then 60% of the rated power. NC:No connection No parallel connection or plug and play. Use dual output simultaneously, forbid opening output pin (0V) to use as single output. Note: 1.The load shouldn't be less than 10%, otherwise ripple will increase dramatically. 2.Operation under 10% load will not damage the converter; However, they may not meet all specification listed. 3.All specifications measured at Ta=25°C, humidity<75%, nominal input voltage and rated output load unless otherwise specified. 4.In this data sheet, all the test methods of indications are based on corporate standards. 5.Only typical models listed, other models may be different, please contact our technical person for more details. RoHS COMPLIANT INFORMATION This series is compatible with RoHS soldering systems with a peak wave solder temperature of 300°C for 10 seconds. The pin termination finish on the SIP package type is Tin Plate, Hot Dipped over Matte Tin with Nickel Preplate. The DIP types are Matte Tin over Nickel Preplate. Both types in this series are backward compatible with Sn/Pb soldering systems. Microdc Professional Power Module,Inc.
