Permalloy for sound and microphone600:10k audio signal step up isolation transformerAudio frequency step-up transformer, ee19 permalloy material winding, permalloy material transformer shield, can filter and shield AC noise interference, digital Weikexing.
CD, MP3, MP4, hard disk player, card holder, LP, multimedia audio source input, the signal is boosted to the next level through the isolation transformer signal.
The 600:10k voltage ratio is 1:4. In other words, the input voltage of 600 Ω is 1V, and the output voltage of 10K winding is 4.082v“4 times of lifting and zooming in.
The core of the transformer is made of 80% ee19mm permalloy. The iron core is white, shiny and reflective, and can be identified at a glance. Permalloy is rust resistant and corrosion-resistant, and can be used for a long time.
E19 core size: length 19mm × height 16mm × stack thickness 5mm. The transformer is shielded with copper foil, which can reduce the leakage inductance and distributed capacitance, and obviously improve the application effect. When using, the shield should be grounded.
High purity oxygen free copper enameled wire winding, select inductance, resistance value similar to sell. The measured value is marked on the transformer. The connection should be correct when using, otherwise it will not work normally“
