Freeshipping 10K: 90K Permalloy audio RCA to RCA signal transformer 3x boost sig

Product Description

10K: 90K transformer parameters:

Primary inductance: about 22H.

Secondary inductance: about 170H.

Primary copper resistance: about 950Ω.

Secondary copper resistance: about 2820Ω.

Overcurrent 15mA.

Frequency response: 10Hz ～ 45KHz -1DB 20Hz ～ 33KHz -0.6DB

Transformers are marked with inductance and resistance values, and selected for close matching and sold.

Permalloy 10K: 90K audio signal transformer, 3 times signal amplification, 3 times passive amplification without electricity, especially suitable for mobile phone or audio source signal amplification, directly driving the rear-stage power amplifier, which is obviously nice, and the effect is immediate. Once you use it, you are unwilling Take off.

10K: 90K impedance description: 10K and 90K refer to the input and output AC impedance of the transformer, not the resistance of the primary and secondary coils (copper resistance), and should not be confused.

10K: 90K Triple boost calculation: The secondary root 90K divided by the primary 10K opens the root number equal to 3, that is, 3 times the boost amplification (the sound is not amplified three times), and it is also suitable for other transformer impedance calculations. Of course, you can also use triple attenuation in reverse.

Transformer amplified signal working principle: When the audio signal enters the primary coil winding of the transformer, the coil and iron core will induce an alternating electromagnetic field, and the alternating electromagnetic field will induce a signal voltage in the output coil winding. Turns ratio, you can get different voltage ratios, you can perform voltage boost amplification, this is the principle of transformer boost amplification.

For example, the input coil of the transformer is wound 10 turns, and the output is wound 30 turns. The input 1V can output 3V, and the signal is boosted 3 times. The turns ratio is also the voltage ratio. .

The signal transformer can work without an external power supply and is a passive amplifier device.

The 3x amplification transformer can improve the sound system without pre-amplification, low volume, and heavy digital taste. It can replace active pre-amplification.

Fixed transformer double panel 63X53mm thickness 2mm shield size 36x28x20mm

This transformer can be used in single-ended to single-ended, single-ended to balanced, balanced-to-balanced, balanced-to-single-ended use, 3x boost, 3x buck, etc.
