P6141T

The P6141T is designed as a plannar power transformer using multilayer PCB technology. It is intended for low profile high frequency DC-DC forward converters up to 500kHz. With careful design, output power exceeding 30W is achievable. P6141T has split primaries and secondaries enabling the device to be configured for 48V and 24V inputs and 5V or 3.3V outputs.

P6141T has seven features. (1)Plannar windings. (2)4mm height above PCB. (3)Low leakage inductance. (4)High frequency operation. (5)Externally configurable. (6)Centre-trapped secondaries. (7)Lead-free (Pb-free). Those are all the main features.

Some absolute maximum ratings of P6141T have been concluded into several points as follow. (1)Its short term isolation voltage 1s would be 500Vrms. (2)Its V.us per primary winding would be 16V.us. (3)Its storage temperature range would be 85°C. (4)Its magnetic core temperature would be 120°C. (5)Its reflow temperature 10s would be 260°C. It should be noted that stresses above those listed in absolute maximum ratings may cause permanent damage to device.

Also some electrical characteristics of P6141T are concluded as follow. (1)Its primary inductance would be min 17uH and typ 25uH and max 35uH with conditions of 100kHz, 100mV each primary winding 2-9,1-10. (2)Its leakage inductance would be max 100nH with conditions of 500kHz, 100mV (1,2)-(9,10) link 3,4,5,6,7,8. (3)Its promary/secondary voltage isolation would be min 500Vrms. (4)Its interwinding capacitance would be typ 308pF with conditions of 100kHz, 1V primary: secondary. (5)Its total transformer losses would be typ 0.7W with conditions of Vout=5V at Iout=5A or Vout=3.3V at Iout=7A 400KHz. (6)Its DCR would be min 17mohms and typ 20mohms and max 23mohms with conditions of primaries 2-9, 1-10 and would be typ 7.5mohms at 3-5, 6-8. (7)Its turns ratio would be typ 1.0. (8)Its operating ambient temperature range would be min -40°C and max +85°C. If you have any question or suggestion or want to know more information about P6141T please contact us for details.
