Chip Type SFECV/SFECK Series

SFECV/SFECK10M7 series for FM receivers are monolithic

type ceramic ﬁlters that utilize the thickness expander

mode of piezoelectric ceramics. SFECV series enable

customers to make an AM/FM set very thin, and it can be

useful to the total chip circuit.

c Features

1. The piezoelectric element is sandwiched by heat

resistant substrate, thus it has excellent mechanical

strength, and it is suitable for automatic mounting.

2. Various bandwidths are available. Select a suitable

type in accordance with the desired selectivity.

3. Operating Temperature Range:

-20 to +80°C (Standard Type)

-40 to +85°C (High-reliability Type)

Storage Temperature Range:

-40 to +85°C (Standard Type)

-55 to +85°C (High-reliability Type)

c Applications

1. Small, thin radios

2. Automotive radios

3. Headphone stereos

Center frequency (fo) deﬁned by the center of 3dB bandwidth.

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 should be an integral multiple of the "Minimum Quantity" shown in the package page.
