Ceramic Filters (CERAFILr) for Communications Equipment

CERAFIL kHz SMD Type SFPKA Series

7.±±±.ꢀ

ꢀ.±±±.ꢀ

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.

(fn) means nominal center frequency 455kHꢀ.

For safety purposes, connect the output of ﬁlters to the IF ampliﬁer through a DC blocking capacitor. Avoid applying a direct current to the output of ceramic ﬁlters.

The order quantity should be an integral multiple of the "Minimum Quantity" shown in package page in this catalog.
