sales representatives or product engineers before ordering.
!Note
The SFPKA series is comprised of small, high performance,
economical, thin (5.0mm) filters consisting of 4
ceramic elements.
Their innovative construction is perfect for shrinking
mobile communication products such as cordless phones,
pagers and transceivers.
1. The filters are mountable by automatic placers.
2. The filters can be reflow soldered and withstand
3. They are slim, at only 5.0mm maximum thickness.
4. The bandwidth ranges from D to H.
5. Operating temperature range: -20 to +80 (degrees C)

Center frequency (fo) defined by the center of 6dB bandwidth.
(fn) means nominal center frequency 455kHz.
For safety purposes, connect the output of filters to the IF amplifier through a D.C. blocking capacitor. Avoid applying a direct current to the output of ceramic filters.
The order quantity shoud be an integral multiple of the "Minimum Quantity" shown in package page in this catalog.
