EMI/RFI Filters (LC, RC Networks) are electrical components used for eliminating or reducing electromagnetic interference (EMI) or radio frequency interference (RFI) in electronic circuits. The ACH4518-472-TD01 is one such EMI/RFI filter designed for AC power application in the automotive industry.

This filter has a working frequency of up to 25 kHz, a commutation time of less than 1 us, and a ripple current of 0.3%. It is composed of an inductor (L), a capacitor (C), and a resistor (R) and has the ability to reduce power line noise. The inductor acts as a low-pass filter, blocking unwanted high-frequency components while only allowing AC power signals to pass through; the capacitor helps provide a path for high frequency currents; and the resistor helps to control both the flow of currents and the overall power level.

The ACH4518-472-TD01 is engineered for AC power application and uses a stacked RC element structure, which helps reduce component height and increase power handling capabilities. Additionally, it is constructed with extremely low series resistance design and has non-magnetic components for shielding applications. It is suitable for a wide operating temperature range of -55°C to +150°C and is rated for up to 7.5A of output current.

The ACH4518-472-TD01 filter is most commonly used in automotive power supply and HVAC systems. It is ideal for applications that require high current, low resistance, and high voltage. In addition, it is also suitable for power systems in mission-critical applications such as medical, aerospace, and automated test systems. It provides pollution prevention through the attenuation of switching noise and waveform distortion caused by common mode conducted interference.

The ACH4518-472-TD01 is a reliable and efficient EMI/RFI filter. Its high current capability and temperature range make it an ideal solution for a wide range of applications. It is designed to improve the performance of power systems and ensure that they comply with EMI/RFI guidelines.
