LMF100CCN/NOPB

The LMF100CCN/NOPB, which belongs to the interface filters active category, is an ultra-low-power power supply noise suppression filter. It is designed to suppress high-frequency noise on power rails caused by switch mode power supplies and other noise sources. Its unique structure enables it to provide a high differential-mode attenuation of up to 12 dB, typically greater than 38 dB at 10 MHz, and a low insertion loss of 0.4 dB typical in the audio band.

The working principle of the LMF100CCN/NOPB is straightforward. It contains power rails with a low on-resistance dropout regulatorNMOS device connected between the input power rail and the shunt capacitor. The shunt capacitor and the NMOS device create a band-pass filter that attenuates noise with spectral components above a certain frequency, while allowing low-frequency signals to pass. This particular device is configured to suppress noise at a frequency range of 15MHz to greater than 200MHz, so it is effective in reducing switching noise in power supplies and microcontrollers.

The LMF100CCN/NOPB is suitable for a wide range of applications. It can be used to reduce noise on sensitive instrumentation circuits, to reduce EMI in data communications systems, and to reduce power supply voltage distortion caused by switching frequencies. In addition, it can be used to suppress Class-B audio amplifier spurs and other unwanted signals on power rails. It is also used in other power conditioning systems, such as switching power supplies, linear regulator power supplies, and AC mains power supplies.

The LMF100CCN/NOPB is a cost-effective noise suppression solution compared to other active noise suppression solutions. It offers a low insertion loss over a wide range of frequencies and offers adjustable high-attenuation while maintaining low capacitance. The device also requires little power and offers a wide input voltage range. In addition, the LMF100CCN/NOPB is lead-free, halogen-free, and RoHS-compliant, making it suitable for power rails in industrial and consumer electronics applications.

Overall, the LMF100CCN/NOPB is an ideal noise suppression solution for low-power, lower-frequency applications. It offers a wide range of features and benefits, making it a cost-effective solution for power rails. Its unique features enable it to provide high differential-mode attenuation and low insertion loss, enabling it to suppress a variety of noise sources. In addition, the device is lead-free and RoHS-compliant, making it suitable for power rails in industrial and consumer electronics applications.
