PEF 20525 F V1.3 is an in-line, powered filter designed for telephone lines for interfacing with telephone carrier systems. It is designed to protect the equipment from high-frequency noise generated by modems, fax machines, and other customer-based communications devices, while providing a smooth transition between the line and the customer-owned equipment.The PEF 20525 F V1.3 filter has a wide operating temperature range of -40°C to +60°C, making it suitable for a variety of harsh environment applications. It offers excellent tolerance to lightning induced transients, as well as being highly resistant to RF interference. The filter is extremely lightweight and can be fitted into most configurations with little to no modifications.The PEF 20525 F V1.3 filter utilizes an innovative design that utilizes low-distortion capacitors and low-source impedance inductors. The capacitors allow for higher-gain boosting of the signal, while the inductors aid in the suppression of high-frequency noise. This filter is designed for direct connection to subscriber-initiated service lines, and does not require any external power source.The PEF 20525 F V1.3 filter is designed for use with any type of service line using standard twisted-pair cabling. It is also capable of handling a variety of line voltages and is capable of suppressing transients up to 545 V peak. The filter is designed to protect the equipment from high-frequency noise generated by modems, fax machines, and other customer-based communications devices, while providing a smooth transition between the line and the customer-owned equipment.The filter also has an in-built design feature to prevent any short circuits due to powering devices with a higher than acceptable current load. The filter also has an anti-dispersive filter for low-frequency noise. This filter provides superior protection from interference generated by nearby radio transmitters, such as those from mobile phones and other wireless devices.The PEF 20525 F V1.3 filter has been designed to the highest standards of reliability and performance, and certified to meet most international standards of quality and safety. It is an excellent choice for use in any application where reliable and consistent noise and interference reduction are a priority. The filter also helps to eliminate cross-talk between multiple service lines and ensures that the signal is free of interference and distortion. It is an ideal filter for use with telephone carrier systems and other applications where a clean, clear, error-free signal is a must.
