Electrical Specifications Inductance (uH) Input Leakage Inductance Inductance Max. DCR(mΩ) Typ. ① Part No. N1 N2 N3 K (Flux Density Factor) (Gauss/A) TTLDE05-20B05D 1140.00±10% 100.00 3680 54 1340 7773 TTLDE05-20B12D 1140.00±10% 100.00 3680 207 897 7773 Notes: ①The test signal of the inductance are 10kHz and 100mV, test the leakage inductance of N1 based on N2 and N3 are shorted; ②To ensure the transformer will not saturate in all of the applications and conditions, the peak flux density(Bm) should remain below 3000Gauss. Use the following formula to calculate the peak flux density: Bm=K*Ipk, Ipk stands for the peak current of input, which unit is A; ③Approximate transformer core loss(Pcv) can be calculated as following formula: Pcv=3.9E-14*f1.82* △ B2.59, the unit of Pcv is W, f stands for operating frequency, which unit is kHz, △B is the operating flux density, which unit is Gauss. △B can be calculated as: △B=K*△I.
