This document introduces the features, applications, dimensions, test circuits and models of the 5CHLW, 5CHW and 5CHT series helical filters.
The TOKO 5CHLW, 5CHW and 5CHT series are compact low‑profile helical filters designed for surface‑mount applications such as cellular phones, cordless telephones and paging devices. The guide provides key performance data, dimensional information and part numbers for each filter type.
Each filter type is presented with its frequency range, bandwidth, insertion loss and other electrical parameters. The tables list individual part numbers, center frequencies and loss specifications, helping engineers select the appropriate filter for a given RF design.
| Frequency Range (5CHLW) | 780 ~ 1150 MHz |
|---|---|
| Frequency Range (5CHW / 5CHT) | 400 ~ 520 MHz |
The 5CHLW filter covers 780 MHz to 1150 MHz.
Yes, the filters are RoHS compliant.
They are suitable for surface‑mounting in cellular phones, cordless telephones, paging devices and similar mobile communications equipment.
