EMI/RFI filters are used to prevent interference or connectivity issues that arise between electrical components due to electromagnetic induction. EMI/RFI filters come in a variety of types, including low-pass, high-pass, band-pass and band-stop. One of the most commonly used EMI filters is the ACH32C-100-T, an inductor-capacitor (LC) filter network.

Applications of the ACH32C-100-T Filter

The ACH32C-100-T filter has several applications within the consumer electronics and telecommunications industry, mainly in radios, TVs, and rotary phones. It is also used in a variety of other devices such as home theater systems, car stereo systems, and video game consoles.

The ACH32C-100-T filter is most commonly used in applications that require the suppression of interference from a wide range of frequencies. It is typically used to suppress radio frequency interference (RFI) and electromagnetic interference (EMI) from other electrical components.

The filter can also be used in a variety of other applications where noise suppression is required, such as light dimmers, motor drives, alarm systems, and amplifiers. In addition, the filter can be used to protect electronic equipment from transient voltage surge events.

Working Principle of the ACH32C-100-T

The ACH32C-100-T filter utilizes an LC filter network to suppress a wide range of frequencies going up to 3GHz. The filter network consists of two capacitors, two inductors, and a single resistor. The capacitors act as high-pass filters, and the inductors act as low-pass filters.

The capacitors are connected in series and have a shared connection at the junction. The inductors are also connected in series and have a shared connection at the junction. The resistor is connected in parallel to the two capacitors to form a low-pass filter.

The filter network works by allowing a certain range of frequencies to pass through while blocking frequencies outside of this range from entering or exiting the circuit. The resistor is used to control the impedance of the filter network, allowing more or less frequencies to be passed through depending on the resistance value.

Conclusion

The ACH32C-100-T filter is an inductor-capacitor (LC) filter network commonly used to suppress radio frequency interference (RFI) and electromagnetic interference (EMI). It is typically used in consumer electronics and telecommunications applications, but can also be used in other applications where noise suppression is required. The filter network works by allowing a certain range of frequencies to pass through while blocking frequencies outside of this range from entering or exiting the circuit.
