The NFL18ST506H1A3D EMI/RFI filter series is designed to protect low power circuits in consumer and communications applications from electromagnetic interference (EMI) and radio frequency interference (RFI). These filters provide circuit isolation to reduce EMI noise, while allowing the circuit to retain its system capabilities. The NFL18ST506H1A3D EMI/RFI filters have a low insertion loss (less than 0.2 dB) and high attenuation values (above 30 dB), making them ideal for applications involving EMI/RFI. These filters are constructed using inductive-capacitive-resistive (LCR) networks, which consist of an inductor, capacitor and resistor connected in parallel and series. The inductor is typically used to block high frequencies, while the capacitor is used to block low frequencies. The resistor is used to dampen the high and low frequencies in order to prevent oscillations. The layout of this network is what determines the filter’s centre frequency, which is where the attenuation is highest.In addition to having high attenuation values, the NFL18ST506H1A3D also offers low leakage of common-mode and differential-mode signals. This is important as it allows the device to remain stable and reliable, even under high frequency, transient signals. The devices are also capable of operating in temperatures ranging from -40°C to +125°C. The NFL18ST506H1A3D is available with either feedthrough or non-feedthrough styles, depending on the application requirements. The feedthrough style consists of a shoulder ring and pole, which provides a secure connection between the filter and PCB. The shoulder ring serves to isolate the outer shell from any RF noise generated by the PCB, while the pole provides an additional layer of shielding. The non-feedthrough style, on the other hand, does not have a shoulder ring or pole, and is designed for applications such as EMI/RFI shielding and noise suppression. The NFL18ST506H1A3D has many applications. It is commonly used for audio, video, automotive and industrial applications, as well as in consumer electronics and communication devices. It has also been deployed to reduce the interference and crosstalk between signals on a PCB, and is suitable for applications where a high degree of EMI/RFI protection is required. Overall, the NFL18ST506H1A3D EMI/RFI filter series is an excellent choice for applications involving EMI/RFI noise reduction. It offers low insertion loss, high attenuation values and low leakage of common-mode and differential-mode signals. These factors, coupled with its wide range of applications, make the NFL18ST506H1A3D a must-have for any one looking for reliable EMI/RFI protection in their circuits.
