Description
15K: 600 / 10K: 10K / 600: 60K / EI35X25mm permalloy fully balanced input and output transformers.
15K: 600 signal 5 times booster amplification, can be used for passive front stage and signal drive
10K: 10K signal 1 to 1, no amplification, can be used for passive front stage and signal isolation.
600: 60K signal 10 times booster amplification, especially for mobile phones or passive signals, the effect is obviously good.
The signal isolation transformer made of big EI35 permalloy material is a single-ended balanced universal conversion transformer. Transformer input three lines, output three lines, can be used as passive front stage, single-ended to single-ended, single-ended to balanced, balanced to balanced, balanced to single-ended use
It is wound with newly imported imported nickel content of 85% permalloy material, the size is EI35 stack thickness 25mm, the riding clip is fixed, and the high purity oxygen-free copper and copper enameled wire is wound.
Use EI35 standard iron core, over signal current 50mA. The primary and secondary layered segmented winding is for dual-group balanced input and output, instead of the conventional two-wire parallel winding method, using a special process, the same number of turns, the same wire diameter, the same copper resistance, the same internal resistance, the same voltage , The current is the same, the positive and negative waveforms have the same upper and lower amplitudes, a completely fully balanced and fully symmetrical signal transformer, full-function conversion, high-precision conversion, good matching, and the effect is immediate. 10K: The frequency response of the 10K signal is 10Hz ～ 145KHz -1.5dB, which is far beyond the audible audio range of the human ear.
Transformer core size: EI35 stack thickness 25mm, slice thickness 0.35mm. External dimensions: 38 × 39 × 42mm riding clip fixed, high purity oxygen-free copper and copper enameled wire winding.
