This is a parameter specification of TFS 465
This document provides the preliminary specification for the VI TELEFILTER TFS 465 RF filter. It lists measurement conditions, nominal and centre frequencies, insertion loss, bandwidth, impedance values and relative attenuation limits. Key performance figures such as a nominal frequency of 465.1375 MHz and insertion loss of 3.8 dB (max 4.5 dB) are included.
The specification also describes the filter's construction and pin configuration, stability requirements (shock, vibration, damp heat, reflow), packaging details for tape‑and‑reel handling, and temperature limits for operation and storage. Additional information such as the minimum bending radius (45 mm) and maximum pieces per reel (3000) is provided.
