DC/DC Transformer CTTURB-20T Series FEATURES 20W flyback transformer in SMD package 4:1 input voltage range and 1650VDC isolation test voltage  Power up to 20W  High saturated flux density  Low DCR loss  Class F insulation  SMD package  ER14.5 Bobbin, Dimensions: 14.70 x 16.00 x 6.80mm  Meets EN62368 standards RoHS TTURB-20T transformer series feature with 1650VDC primary to secondary isolation, an operating ambient temperature range of -40℃ ~ +125℃. It can be used with our control IC SCM1101AMA to achieve flyback power supply design with an 4:1 wide input volatge range and various protection functions and superior EMI performance.

Electrical Specifications Inductance(uH) Leakage Input ① Inductance Max. Inductance Part No. 6.86±12% CTTURB2405-20T 1 DCR(mΩ) Typ. N1 N2 N3 N4 N5 N6 23 59 12 12 93 273 K (Flux Density Factor) (Gauss/A) 572 Notes: ①Approximate leakage inductance: test the inductance of N1 and N2 in parallel based on N3, N4, N5 and N6 are shorted; ②To ensure the transformer will not saturate in all of the applications and conditions, the peak flux density(Bm) should remain below 3000 Gauss. 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. General Specifications Item Operating Conditions Min. Typ. Isolation Pri-Sec Electric Strength Test for 1 minute with a leakage current of 1mA max. 1650 Surface operating ① Temperature Storage Humidity Non-condensing Storage Temperature ② Max. Unit -- -- VDC -40 -- +125 ℃ 5 -- 95 %RH -55 -- +125 ℃ Peak temp.≤245℃, maximum duration time≤60s over 217℃. Reflow Soldering ③ Temperature Notes: ①The temperature of the transformer(ambient plus temperature rise) should be within the surface operating temperature range; ②The storage temperature of the transformer only; ③Please refer to IPC/JEDEC J-STD-020D.1. And we suggest that times of reflow soldering should not exceed twice. Mechanical Specifications Dimensions 14.70 x 16.00 x 6.80mm Weight 3.00g (Typ.)
