SMD Audio Frequency Transformer,
Toroidal Audio Frequency Transformer,
20kHz Audio Frequency Transformer
SMD Audio Transformers With 20Hz To 20kHz Frequency And Maximum Response Of 0.25dB
In radio communication, radio and television, automatic control as voltage amplifier, power output circuit components.The frequency response of the audio transformer is uniform in the working frequency band, and its iron core is stacked with high magnetic conductivity materials. The primary and secondary windings are tightly coupled, so that the magnetic flux through the primary winding is almost all in chain with the secondary winding, and the coupling coefficient is close to 1.The lowest frequency of the passband is determined by the original winding inductance and the highest frequency is determined by the transformer leakage inductance.To ensure that the transformer has enough passband, the primary winding inductance should be large, the leakage inductance should be small.The hysteresis loss and magnetic circuit saturation of the core will cause the signal distortion.The influence of hysteresis loss can be reduced by properly configuring the load and increasing the load current.Increasing the core section and leaving an air gap can make the magnetic circuit not saturated, thus reducing the distortion of the signal.
Output transformer: used in audio equipment and playback equipment, the role of impedance conversion in the circuit.
Input transformer: the main role is in the input of sound signal occurs, in the circuit plays the role of impedance conversion.
Interstage transformers: Common interstage transformers are used to harmonize the various working units in the amplifier.
Interwire transformers: Interwire transformers are commonly used in wired broadcasting equipment.Because there are many high-power amplifiers on the wired broadcast unit, and the line is long, the transmission of audio over a long distance will make audio distortion
