Power line filter modules are essential components for industrial electronic systems, as they reduce noise generated by electromagnetic interference (EMI). The NBH-20-221-D power line filter module is a compact and reliable component designed to meet stringent requirements in the automotive and medical optoelectronic industries as well as other industrial applications. It provides protection from interference in industrial AC power systems.

The NBH-20-221-D filter module is a single-stage EMI filter with galvanic isolation between the input and output of the filter. This type of filter has two ports, one for the input of the AC power supply and one for the output. The input is filtered by the filter module before it passes through to the output. The module includes capacitors, inductors, and resistors that form a low-pass filter. The filter reduces levels of interference in the input signal, and a differential mode filter ensures that any remaining interference is adequately suppressed.

The NBH-20-221-D module has a dual-channel, differential mode filter that is effective over the range of 0 Hz to 9kHz. This ensures that a wide range of interference frequencies is suppressed. The filter has a very high attenuation by as much as -80dB in the frequency range of 0.1 MHz to 9kHz. The module also offers excellent common-mode rejection up to 30 dB, making it effective in suppressing interference from multiple sources.

The module is designed to have a minimum insertion loss in order to reduce the impact of the filtering process on the quality of the output signal. This is achieved by optimizing the filter elements and the layout of the circuit board to minimize any interference. Furthermore, the module has high signal integrity with very low noise and distortion levels, providing a clean signal to the system.

In addition, the NBH-20-221-D filter module is designed for long-term reliability. It has an operating temperature range of -55°C to +85°C and has a robust housing making it suitable for harsh industrial environments. The module also has high surge current capability for improved protection against transients.

The power line filter module is a reliable and efficient way to reduce the level of noise generated by electromagnetic interference (EMI) in industrial AC power systems. The NBH-20-221-D module is a compact and reliable component that offers excellent noise suppression with high signal integrity and long-term reliability.
