The 1204-050 filter is an electromagnetic compatibility (EMC) device that provides an effective solution for suppressing the disturbances created by conducted and radiating emissions. This filter is an EMI/RFI filter of the LC or RC networks category, meaning that it is composed of lumped components such as inductors, capacitors, and resistors.The 1204-050 is designed for use in DC power line applications, providing noise reduction of conducted emissions. It features a compact design, which is ideal for applications with tight spaces, such as notebooks, smartphones, and tablets. It is a low-profile EMI filter, with an installed height of only 0.5 inches.The working principle of the 1204-050 filter is relatively simple: it utilizes the resistive, inductive, and capacitive impedance of the components within the filter network to attenuate conducted and radiating emissions. By using the principles of parallel and series resonance, the filter can effectively reduce conducted and radiating emissions.Resistance is provided by the filter core material, which is basically a coil of wire. This resistance limits the amount of current that can flow through the circuit, thus reducing the amount of electromagnetic radiation that is emitted. Inductance is provided by the filter\'s internal inductors, which are typically wound with multiple turns of wire. This inductance creates a magnetic field around the filter, which serves to "trap" and absorb energy emitted by nearby circuitry. Capacitances are also included in the filter network, which serve to absorb even more energy.In addition to providing emissions suppression, the 1204-050 filter also provides protection from over-voltage and over-current conditions. This feature can come in handy in applications where unexpected power interruptions or surges may occur. The filter works by limiting the voltage and current that can flow through the circuit, thus protecting sensitive components from being damaged.Overall, the 1204-050 filter is an effective and efficient means of reducing conducted and radiating emissions, while also providing protection from over-voltage and over-current conditions. By combining the principles of resistance, inductance, and capacitance, the filter can drastically reduce unwanted noise, allowing for a quieter and more reliable system operation.
