Double Trap Filters (XT MW)

Direct (XT MW) are Murata Double Trap Filters TPWA Series Compatible. Trap filter is a ceramic filter passes only particular frequency. To the contrary, Band Eliminate Filter (B. E. F.) which blocks or attenuates particular frequency is called trap.

Sound trap for TV set is one of the famous example of B. E. F. In TV set, video signal is used in picture amplitude circuit after video signal detection block, ceramic resonator is insert here and trap circuit is formed in order to eliminate sound signal involved in video signal.

Direct Double Trap Filter (XT MW) Series consist of 2 wafers with 2 trap frequencies. Recommended for Multi standard set. Features with good performance of attenuation and space saving with 3-terminal type. The characteristic of a three-terminal ceramic trap equals two two-terminal ceramic trap. Three-terminal ceramic trap has a monolith structure formed from 2 ceramic resonators.

Full line products meet RoHS compliant. Direct will also produce devices outside these specifications to meet specific customer requirements, please contact our sales for more information. Download Three-Terminal Double Trap Filters (XT MW) Datasheet PDF (293KB).
