Introduction

Barrel Audio Connectors are round, cylindrical connectors frequently used in audio applications. It is designed to provide optimal sound quality and secure connections between two audio devices. A common example of the Barrel Connector is the SJ2-3544A-SMT-TR. In this article, we will discuss the application field and working principle of the SJ2-3544A-SMT-TR.

SJ2-3544A-SMT-TR Specifications

The SJ2-3544A-SMT-TR is built with durability and stability in mind. It is constructed from high-grade materials and meets all standards for audio connectors. The specifications for SJ2-3544A-SMT-TR includes:• Contact resistance of ≤ 5mΩ• Total connected current of 2A• Working voltage of ≤ 250V• Inner dimension of 7.62mm• Outer dimension of 11.4mm• Insulation resistance of > 500MΩ @ 500V DC• Frequency range of 5Hz- 30kHz• Contact material of phospher bronze

Application Field

The SJ2-3544A-SMT-TR is versatile and has a wide range of applications. Its highly durable construction and ability to handle low-level signals with quality output makes it suitable for many audio connections. Some of the common applications of this connector are:• Home entertainment systems • Professional audio and sound systems • High-quality microphones and sound link systems • Musical instruments and amplifiers • Loudspeaker systems • PA systems • Automotive audio systems

Working Principle

The SJ2-3544A-SMT-TR is designed to securely hold and transfer low-level audio signals between two connected devices. It does this by providing a solid metal conductor between the two devices and a barrier of insulation to keep the signal from leaking out or being distorted.The barrel audio connector uses two copper wires. When the connector is inserted, it creates two points of contact. The inner wire sends a signal to the other device, while the outer wire acts as a ground. This means that the signal is amplified before it is sent through the outer conductor. The insulation of the barrel audio connector is also important. It ensures that the low-level audio signals are not distorted by other electrical signals or other forms of noise. The SJ2-3544A-SMT-TR allows signals to travel with far less distortion and allows the user to enjoy the highest possible audio quality.

Conclusion

The SJ2-3544A-SMT-TR is a durable and reliable barrel audio connector that provides high-quality sound and secure connections. It has a wide range of applications, from home entertainment systems to automotive audio systems. Its excellent design and performance make it the perfect choice for any audio device. Its two copper wires and insulation make sure that the signal is not distorted and the user can enjoy the highest possible sound quality.
