The Coilcraft WA8515-ALD is a 25W Forward Mode Transformer specifically designed for Power over Ethernet (PoE) applications. It operates with an input voltage range of 20-57V and is developed for use with Texas Instruments TPS23754 PWM Controller.
Key electrical specifications include a minimum inductance of 90µH measured at 250 kHz, 0.1 Vrms, 0 Adc. The transformer offers a primary DCR of 146 mOhms max, secondary DCR of 25 mOhms max, and bias DCR of 494 mOhms max. Leakage inductance for the primary is a maximum of 0.816µH. The turns ratio is 1:0.406 for primary to secondary and 1:0.813 for primary to bias. The output is rated at 5.0V with 4.8A, and the bias winding output is 12V at 20mA.
This transformer has 1500 Vrms isolation between primary and secondary windings for one minute. It is constructed with a ferrite core and features RoHS tin-silver-copper over tin over nickel over phosphor bronze terminations. The component has a weight of 6.7g and operates within an ambient temperature range of -40°C to +85°C, with a maximum part temperature of +125°C.
The WA8515-ALD is designed for surface mount applications and comes packaged 175 pieces per 13" reel. It is suitable for PCB washing tested to MIL-STD-202 Method 215 plus an additional aqueous wash. The maximum part temperature during soldering reflow is +260°C for a maximum of three 40-second cycles.
