Product Description

Permalloy 600Ω: 15K audio signal isolation transformer, 5 times boost, 5 times passive amplification without electricity, the measured value is marked on the transformer, and the transformer is equipped with a shielding cover for sale!
The 5x passive amplification without electricity is especially suitable for mobile phone or audio signal amplification to directly push the power amplifier. It is obviously powerful and good, and the effect is immediate. Once used, it is unwilling to remove it.
For example, the input coil is wound with 10 turns, the output is wound with 50 turns, the input is 1V and the output is 5V, and the signal is boosted and amplified by 5 times. And without power supply, it belongs to passive amplification.
The 5 times amplifier transformer is also suitable for audio systems without pre-amplifiers, and the volume is small and can not be listened to. It can replace active pre-amplifiers. It is also suitable for audio systems without pre-amplification and low volume.
600Ω:15K transformer frequency response: 20Hz ~ 39KHz -1.8DB, imported permalloy iron core, winding of oxygen-free copper and red copper enameled wire.
The recording and playback head of the reel-to-reel tape drive uses a permalloy transformer
Use the wiring as follows:
This transformer can be used as a passive front stage, single-ended to single-ended, single-ended to balanced, and balanced to single-ended use.
I don't know how to use the wiring when I buy a transformer. Please contact customer service when you take the photo. The wiring diagram will be attached to the delivery.
Board size: 63X53mm double panel thickness 2mm Shield size: 36x28x20mm

600Ω:15K transformer parameters:

Primary inductance: about 7H.

Secondary inductance: about 120H.

Primary copper resistance: about 390Ω.

Secondary copper resistance: about 1960Ω.

transformer overcurrent is 15mA.

Frequency response: 20Hz ～ 52KHz -2DB




transformer is marked with the inductance and resistance value, and the similar matching is selected for sale.600Ω:600Ω, 600Ω:10K, 600Ω:60K, 600Ω:20K, 600Ω:15K, 10K:20K, 10K:90K, 10K:600Ω and other transformers can also be customized according to requirements.I don’t know how to use the wiring when I buy a transformer. Please contact customer service when you take the photo. Technical support for this product!The soft iron of this transformer shielding iron cover is first plated with copper and then nickel, and finally baked with a paint process, which has the effect of anti-magnetic interference and electrostatic shielding, reducing noise and interference.
