Ceramic Miniature Filter
450 kHz~470 kHz (MLT)
Introduction (MLT)
One of The Most Recommendable Intermediate Filters for AM (Murata PFB Compatible). Token miniature ceramic filters for AM is one of the most recommendable intermediate filters, having such distinctive features as high selectivity, high stability and adjustment-free operation.
Additionally its easy matching with IC helps create an easy circuit design such as applications in Electric synthesized tuners, HiFi audio systems, AM stereo demodulations, One-chip non-adjustment IC's, and even smaller, thinner set structure to cope with these diversifying for AM receiver.
Features with center frequency between 450 and 470 kHz, standard tolerance ±2kHz, and synthesizers for the types of center frequencies 450, 459 and 468 kHz. Standard tolerance is ±1 kHz.
