EXC-28CG900U Filters

Common Mode Chokes is an electronic component capable of suppresing the current or voltage in a single circuit. By doing so, it can be used to effectively eliminate electrical noise generated by the circuit, and its applications include power supplies and signal applications. The EXC-28CG900U, in particular, is a common-mode choke that is suitable for use in signal and power line applications, providing an effective reduction of electrical noise and electromagnetic interference.

The EXC-28CG900U is a toroidal common-mode choke that consists of two coil windings wrapped around a ferrite core. The two winding coils create a magnetic field when current flows through them, and this field is used to oppose the flow of current, reducing its amplitude. The choke also has a capacitance, which helps to reduce EMI (Electromagnetic Interference).

The EXC-28CG900U is designed for use in signal and power line applications, such as filter circuits, communication circuits, phase units, and auto-transformer circuits. Its high-saturation and high-permeability characteristics allow it to effectively reduce both high-frequency and low-frequency noise. Additionally, its low inductance and resistance characteristics are well-suited for use in power-supply circuits. The choke also has a high AC-DC current ratio, making it suitable for use in power circuits that require low-frequency noise suppression.

In addition to being used in signal and power line applications, the EXC-28CG900U can also be used in various noise reduction and control circuits. In these applications, the choke can be used to reduce radio-frequency interference, or RFI. For example, it can be used in systems designed for radio-frequency identification, or RFID, to suppress interference from external radio-frequency sources. It can also be used in audio and video systems to reduce low-frequency noise that can cause signal quality issues.

Overall, the EXC-28CG900U is a high-performance common-mode choke designed for signal and power line applications. It offers excellent noise suppression capabilities and is suitable for use in numerous types of circuits. Its high-saturation and permeability characteristics make it well-suited for use in power-supply circuits, while its low inductance and resistance characteristics make it suitable for use in noise reduction and control circuits. As such, the EXC-28CG900U is an effective and versatile solution for eliminating electrical and radio-frequency interference.
