Product Overview
The B39871B3717U410 is a high-performance surface acoustic wave (SAW) bandpass filter manufactured by TDK-EPCOS, designed for RF front-end frequency selection in wireless communication equipment. Fabricated with mature piezoelectric substrate technology, this SMD component delivers excellent in-band insertion loss and high out-of-band stopband attenuation to eliminate adjacent-channel interference and spurious RF noise. Compact miniaturized surface-mount form factor enables high-density PCB layout and fully automated SMT assembly during mass production. It maintains stable frequency filtering performance across varying temperature conditions and serves as critical frequency screening component for cellular modules, IoT wireless devices and portable radio transceiver circuits.
