Compact Design EI19 Permalloy Audio Isolation Low Frequency Transformer 3+3 Pins

 1.Product Description

The EI19 Low Frequency Transformer is a specialized electrical component designed to meet the demands of low - frequency applications. Its compact EI19 - shaped core, typically made of laminated ferromagnetic materials, is engineered to efficiently transfer electrical energy at frequencies ranging from a few hertz to several kilohertz. This design significantly reduces core losses, such as hysteresis and eddy - current losses, ensuring high - efficiency operation. The compact size of the EI19 transformer makes it an ideal choice for applications where space is limited, like in small - scale industrial control panels, audio power amplifiers focusing on bass frequencies, and some low - voltage power supplies. By stepping up or stepping down voltages according to the turns ratio of its windings, it plays a crucial role in providing the appropriate voltage levels for various low - frequency - based electrical equipment, enabling stable and reliable performance in these applications.

2.Specificities

1. Energy efficient core structure
--Low-loss core material: The EI19 low-frequency transformer utilizes an EI19-type core made of laminated ferromagnetic material. This material has a high permeability and is capable of inducing and transmitting magnetic fields efficiently at low frequencies. The laminated structure effectively reduces eddy current losses and minimizes wasted energy due to current circulation within the core. At the same time, the properties of the material itself also keep hysteresis losses at a low level, i.e., when the magnetic field changes repeatedly, the core absorbs and releases energy with minimal loss in the process. The reduction of these two losses makes the transformer in low frequency operation, the overall energy conversion efficiency significantly improved, can be more input power into useful output power, reduce energy consumption.

--Optimized winding design: The windings are wound according to the precise turns ratio based on the transformer's voltage conversion requirements. Precise turns control ensures the accuracy of voltage conversion, and in the process of boosting or bucking, it can strictly output the voltage value that meets the requirements of the equipment. Moreover, the winding adopts low-resistance wire material, which further reduces the resistance loss when the current passes through the winding, improves the power transmission efficiency, and provides reliable power guarantee for the stable operation of the equipment.

2.Precise adaptation to low-frequency applications
--Wide frequency and low noise operation: specially designed for low frequency application scenarios, the working frequency range covers from a few hertz to several thousand hertz. Within this frequency range, the transformer can operate stably without additional noise or performance degradation due to frequency fluctuations. For some equipment with strict requirements for low-frequency signal processing, such as audio power amplifiers focusing on bass frequencies, the EI19 low-frequency transformer is able to accurately process low-frequency signals to ensure the reproduction and stability of audio signals, bringing users a high-quality bass listening experience.

--Stable Voltage Conversion: Under low frequency conditions, it is capable of stable voltage step-up or step-down operation according to the winding turns ratio. Whether it is in industrial control, converting high voltage to low voltage suitable for small equipment, or in certain low voltage power supply applications requiring specific low voltage, it can accurately output the required voltage to meet the stringent voltage requirements of different equipment and ensure the normal operation of the equipment.
