> ETD49 transformer cores, power ferrite, 500MT bsat (X2
ETD49 transformer cores, power ferrite, 500MT bsat (X2
Qty: 1 complete transformer (2 halves)
Permeability = 3000, B(sat) = 500 mT
Dimensions: 49mm x 25mm x 16.3mm each half.
Magnetic Path length: 11.562 cm
iNDUCTANCE iNDEX (AL): 4825 nH/N^2
ETD is the most power-efficient shape for high frequency power transformers

Note: Depending on construction, an ETD49 core can produce 1-2KW max power, while an ETD44 can produce 700W-1.4KW. Maximizing factors will include a full bridge topology, 100KHz+ operating frequency, and use of triple-insulated winding wire to optimize transformer performance.
Material: ASTM P5025 ( TSF50 ) power ferrite.
Manufacturer's QC certification sheet for this lot adds the following information:
Al value: 4966 nH / T^2 +/- 25%,
average of 16 samples from the lot, taken with an Agilent 4275A LCR Analyzer,
