Additional Details:

This SAW filter operates on a piezoelectric substrate with interdigital transducers (IDTs) that generate and detect surface acoustic waves. The IDT design determines the filter's performance characteristics such as center frequency, bandwidth, and impedance. The suffixes "AJ25B", "W310", and "A01" represent specific performance and packaging details. Always consult the official EPCOS (TDK) datasheet for comprehensive specifications and application guidelines.
