Power line filter modules are essential components in any electrical system. They help to ensure that the noise and voltage fluctuations from one electrical device are kept in check so that the control signals are unaffected and the power to the device is uninterrupted. The PAN4820 line filter module is one such line filter module which provides superior performance in a compact package.

The PAN4820 power line filter module is a small, off-the-shelf solution for low-cost, space-saving power filtering. It’s designed to provide both EMI filtering and differential-mode noise filtering, and is capable of filtering out high-frequency interference from 100KHz to 10MHz. This makes it ideal for applications which require power line filtering for high speed signals, such as Ethernet, CAN and other communication systems. The PAN4820 features an integrated common-mode choke with excellent EMI performance, as well as a highly-efficient passband for differential-mode noise filtering. In addition, the module is shielded for robustness and performance in an EMI environment.

The PAN4820 is ideal for applications such as digital audio and video systems, microcontrollers, motor controllers, power supplies, and other applications which require noise filtering. It features an 8000VAC breakdown voltage and a wide operating temperature range of -40°C to +105°C. The PAN4820 is housed in a small, off-the-shelf PCB with an optional housing for more robustness. The module also features an integrated voltage monitor, which can be used in conjunction with a microcontroller to monitor the power line and take corrective action if necessary.

The working principle of the PAN4820 power line filter module is simple but effective. The module has two main components, an EMI filter and a differential-mode filter. The EMI filter is designed to suppress noise signals from external sources, while the differential-mode filter is designed to suppress noise on the power line itself. Together, these two filters work to ensure power is clean and noise-free. The voltage monitor then ensures that the microcontroller is aware of any voltage changes on the power line.

In summary, the PAN4820 power line filter module is a small, off-the-shelf solution for low-cost, space-saving power filtering. It provides superior performance in an ultra-compact package, and is ideal for applications such as digital audio and video systems, microcontrollers, motor controllers, and power supplies. The integrated common-mode choke and powerful passband ensure robustness and performance, while the voltage monitor ensures the microcontroller is aware of any changes to the power line.
