EMI/RFI filters are electrical components designed to limit electromagnetic interference (EMI) and radio frequency interference (RFI) signals from the power supply. In specific applications, EMI/RFI filters isolate electrical circuits, allowing only desired signals to pass through. Filters using inductors and capacitors are used to create low-pass, high-pass, and band-stop characteristics. ACF451832-223-TD01 is an EMI/RFI filter, typically used in critical applications, such as computers, medical, and military equipment.

The ACF451832-223-TD01 filter has been designed for improved performance, compared to other EMI/RFI filters. It has a low insertion loss, from 20Hz to 1GHz, with minimal signal distortion. The filter components are constructed with high-reliability military-grade components and hermetically sealed. This makes it suitable for high-temperature applications and extends its operational lifetime. It also has an exceptionally low noise floor, useful for applications requiring low-noise operation.

The ACF451832-223-TD01 filter features two stages of filtering, a low-pass stage and a high-pass stage. The low-pass section consists of a series combination of an inductor and a capacitor. This combination creates a notch filter, eliminating frequencies above the cutoff frequency. The filter is optimized to suppress frequencies between 1MHz and 20MHz. The high-pass section consists of a parallel combination of the same components. This combination creates a low-pass filter, eliminating frequencies below the cutoff frequency. The filter is optimized to suppress frequencies between 0.25MHz and 1MHz.

The ACF451832-223-TD01 filter is typically used in systems where low noise and good EMI/RFI compliance are required. It is especially useful in commercial, medical, and military applications where reliability is essential. It has been tested to meet stringent military standards, such as Bellcore, MIL-STD-2207-A and MIL-STD-462-C, ensuring the highest possible level of EMI/RFI performance.

The ACF451832-223-TD01 filter is a low-cost, high-performance option for applications where performance, reliability, and cost are important factors. With its two stages of filtering, it offers excellent EMI/RFI suppression performance, with minimal effect on the desired signal. Its robust construction makes it suitable for high-temperature applications, while its low insertion loss provides improved signal clarity.
