Description:
3858 is a 1:1 line matching transformer which has five unique features: The first one is it has low profile. The second one is that it has small volume. The third one is its conforming to FCC part 68, canadian CS 03 regulations. The forth one is it has low cost. The fifth one is it has high insulation voltage. Otherwise , it also has three main applications. The first one is those interfacing equipment to telephone line. The second one is those requiring small size and high insulation voltage. The third one is 3858-2 is designed for high impedance bridging applications.Edited by http://www.seekic.com/icdata/3858-X.html the leading IC purchasers' best choice of platform for one-stop valued service!
Then, there are also 3858-X some electrical specification (@25 °C) about it. Impedance ( Ω ) is 600 : 600 (3858), 600 : 600(3858-1), 10 K : 10 K(3858-2) ,10 K : 10 K(3858-3). Insertion Loss ( dB ) (@ 1000 Hz) is less than 1.0 (3858), less than 1.0 (3858-1), less than 0.5(3858-2), less than 0.5(3858-3). Frequency Response ( dB ) (300 – 3500 Hz) is less than 1.0 (3858), less than 1.0 (3858-1), less than 0.5(3858-2), less than 0.7(3858-3). Longitudinal Balance ( dB ) (300 – 3500 Hz) is bigger than 65(3858), bigger than 65(3858-1),bigger than 65(3858-2),bigger than 65(3858-3). Dielectric Strength (Vrms) is 4000 Vrms (3858), 4000 Vrms (3858-1) , 2500 Vrms (3858-2), 2500 Vrms (3858-3). |
