Common mode chokes are electrical components used to reduce the unwanted effects of electromagnetic interference (EMI) in a system by blocking the common-mode current rather than the differential-mode current. A common-mode choke, also known as a common-mode filter, is a type of electrical filter specifically designed to reduce the amount of noise in a system caused by electromagnetic fields. In this article, we will explore the application field and working principle of TF2514HU-101Y5R0-01, a common-mode choke produced by TEConcepts.

Introduction

Common-mode chokes are used in a variety of electronics applications, most commonly in power lines, signal lines, or data lines. The purpose of the common-mode choke is to block the common-mode current, thereby reducing the amount of noise in the system and eliminating EMI. Common-mode chokes are used in a variety of applications, such as in automotive electronics, industrial electronics, medical electronics, telecommunications, aerospace, and consumer electronics. Common-mode chokes are also used in power tools, security systems, and instrumentation systems.

TF2514HU-101Y5R0-01

TF2514HU-101Y5R0-01 is a common-mode choke produced by TEConcepts. It is a three-winding common-mode choke designed to reduce common-mode interference in systems with a bandwidth of up to 100MHz. It is designed to reduce both external and internal electromagnetic interference (EMI). The device consists of three winding coils: primary, secondary and tertiary winding coils, with each winding consisting of 100 turns of wire. The maximum operating temperature of the device is 125°C.

Application fields

TF2514HU-101Y5R0-01 is a versatile common-mode choke designed for a variety of applications, including automotive, industrial, telecommunications, consumer, instrumentation, and lighting applications. The device is ideal for suppressing the electromagnetic interference (EMI) generated by switching power supplies, thermal, sonic, or static noise. It can be used in high-frequency signal transmission lines, AC power lines, and Pulse Width Modulation (PWM) control which provides a stable connection and less signal loss. The device can also be used for signal suppression and noise reduction in data lines for Hi-Fi audio. Additionally, the choke is suitable for the reduction of common-mode interference in the LED lighting system.

Working principle

TF2514HU-101Y5R0-01 works by blocking the common-mode interference current generated by the presence of electrical noise. The noise in the system is referred to as a differential-mode current, as it is composed of two equal, out-of-phase components, one flowing in each direction. The choke is designed to suppress the higher-frequency differential-mode current and allow the lower-frequency common-mode current to pass through, thereby reducing the amount of noise in the system. This is done by the primary and secondary winding coils acting together to isolate common-mode interference. The tertiary coil ensures high impedance to the common-mode current, which helps to further reduce the noise level in the system.

Conclusion

Common-mode chokes, such as TF2514HU-101Y5R0-01, are important components for reducing unwanted noise in electronic systems. The device is versatile, suitable for a variety of applications, including automotive, industrial, telecommunications, consumer, instrumentation, and lighting applications. It works by blocking the common-mode interference current generated by the presence of electrical noise, and its three winding coils act together to isolate the common-mode interference and reduce the amount of noise in the system.
