Electromagnetic interference (EMI) and radio frequency interference (RFI) filters are key technologies for mitigating these problems in many different applications. The ACF451832-153-TD01 is a prime example of a filter designed specifically to suppress EMI/RFI interference. In this article, we will discuss the application of the ACF451832-153-TD01 and its working principle.

Application Field

The ACF451832-153-TD01 EMI/RFI filter is designed to block or reduce the levels of noise generated from EMI and RFI sources such as switching power supplies, motors, and even transmitters. It can serve a variety of applications, including but not limited to: automotive, industrial (including, but not limited to, railway control systems, industrial process control systems and communication systems, etc.), medical (including, but not limited to, MRI systems, X-ray systems, and other medical imaging systems, etc.), and commercial (including, but not limited to, computers, cell phone base stations, communication systems, etc.). This filter is especially suitable in industries where electromagnetic compatibility and radiation control are critical.

Working Principle

ACF451832-153-TD01 employs a multi-level set of capacitors and inductors to produce a low-pass filter that operates according to the RLC (resistor-inductor-capacitor) model. The filter blocks high-frequency noise while maintaining a very low insertion loss across the pass band. It also provides a high suppression factor (attenuation) across the stop band. The filter utilizes a multi-level LC (inductors and capacitors) complex network to provide better noise attenuation and improved shielding effectiveness.

The filter has a maximum working voltage (DC) of 450V, maximum operating temperature range of -40C to +85C, and a maximum frequency range of 18 to 2150 kHz. It is also designed with flexibility in mind, allowing for various combinations of capacitances and inductances to be tailored for specific applications. The filter is shielded, with termination contacts being plated in tin-lead to ensure a greater signal path.

The ACF451832-153-TD01 filter has been tested to meet the requirements of various international EMI/RFI standards such as the EN 55011 (EMC), EN 50121-4 (railway), EN/IEC 61373 (railway), and FCC Part15/17 (consumer electronic products). The filter is also UL-approved and ROHS compliant.

Conclusion

The ACF451832-153-TD01 EMI/RFI filter is the ideal solution for many applications where good electromagnetic compatibility and radiation control are critical. The filter\'s low-pass filter design, impressive maximum working voltage, temperature range, and frequency range make it suitable for a variety of applications in various industries. The filter is also UL-approved and ROHS compliant, providing assurance of its safety and quality.
