PCB Mount Permalloy Audio Isolation Transformer with Pin/Electronic Wire

1.Product Description:

PCB mounted Permalloy audio isolation transformer with pins/electronic wires, designed specifically for printed circuit boards (PCBs), is a key component for improving audio signal quality. Its core is made of Permalloy , which is known for its high magnetic permeability and low hysteresis loss. It can efficiently couple signals in the audio frequency band while minimizing signal distortion to the greatest extent possible. The configuration of pins and electronic wires makes it easy to connect transformers to other components on the PCB, ensuring stable and reliable electrical connections within a compact circuit board space.

In audio equipment, it plays an important role in electrical isolation, effectively cutting off the ground loop, preventing noise interference caused by ground potential difference, and ensuring the purity and purity of audio signals. With excellent frequency response characteristics, this transformer can accurately reproduce various audio signals from low to high frequencies, bringing high fidelity audio experience to audio systems, recording equipment, etc. It is an ideal choice for PCB circuit design that pursues high-quality audio output.

2.Characteristic

1. Excellent electrical performance
--High magnetic permeability: Permalloy magnetic cores are used, which have extremely high magnetic permeability and can efficiently concentrate and guide magnetic fields, enhance electromagnetic coupling between primary stages, ensure minimal loss of audio signals during transmission, and significantly improve the transmission efficiency and fidelity of audio signals. For example, when processing complex music signals, it can accurately restore the details of each note.

--Low hysteresis loss: Permalloy's low hysteresis loss characteristics result in extremely low energy loss during the repeated magnetization and demagnetization processes of the magnetic core under alternating magnetic fields. This helps to reduce the heat generated during the transmission of audio signals, reduce signal distortion caused by thermal effects, and ensure the purity and stability of audio signals.
--Broadband response: With an extremely wide frequency response range, it can cover the full audio frequency range audible to the human ear (20Hz-20kHz) or even wider. Whether it is low bass, rich midrange, or crisp treble, they can be accurately transmitted and isolated to meet the strict requirements of high fidelity audio equipment for full frequency band signal processing.

--Good isolation performance: It can effectively isolate the electrical connection between primary and secondary circuits, cut off the ground loop, and avoid noise and interference signals introduced by factors such as ground potential difference and electromagnetic interference from entering the audio signal path. This makes the output audio signal purer, without noise or buzzing, significantly improving audio quality.

2. Convenient PCB installation
--Pin design: Equipped with specially optimized pins for PCB installation, the spacing, shape, and length of the pins comply with the standard specifications of PCB design, making it easy to directly insert them into the pre designed mounting holes on the PCB. Through conventional soldering processes such as wave soldering and manual soldering, a firm electrical connection can be achieved, ensuring a stable installation on the circuit board without easy loosening.

--Electronic wire connection: The accompanying electronic wires provide convenience for specific connection needs or connection with external devices. Electronic wires have good flexibility and electrical performance, allowing for flexible wiring and meeting the requirements of different PCB layouts and equipment connections.

--Compact structure: The overall structure is compact, with a small volume that can efficiently layout within limited PCB space without occupying too much space. It is easy to integrate tightly with other audio processing components such as amplifiers, filters, etc., meeting the design trend of miniaturization and integration of modern audio devices.

3. Reliable stability and durability
--High quality materials: In addition to Permalloy magnetic cores, other components of transformers (such as winding wires, insulation materials, etc.) are also made of high-quality materials to ensure stable electrical performance under different working environments (such as temperature and humidity changes). For example, the winding wire adopts high temperature resistant and wear-resistant enameled wire to extend the service life of the transformer.

--Good heat dissipation: Although the hysteresis loss and heat generated by winding resistance are low during operation, the transformer still considers heat dissipation factors in its design. Its compact structure is conducive to natural air convection heat dissipation, ensuring that performance will not decrease due to overheating during long-term continuous operation, and ensuring the stability and reliability of audio signal processing.
