Ceramic Filters (CERAFIL

r) for Communications Equipment

CERAFIL

r MHz SMD Type SFSCE10M7 Series

SFSCE series are chip surface mount filters available for

3dB bandwidth at 700kHz to 1.3MHz. (more than twice

width compared with current types)

They have 1.0mm max. thickness and small mounting area

(4.5x3.8mm).

c Features

1. The filters are mountable by automatic placers.

2. They are slim, at only 1.0mm max. thickness, and

have a small mounting area (4.5x3.8mm) enabling

flexible PCB design.

3. Available lead (Pb) free solder reflow.

4. Operating temperature range:

-20 to +80 (°C)

Storage temperature range:

-40 to +85 (°C)

c Applications

1. SS digital communication system

2. Digital wireless audio

3. PHS Evolution system

4. RFID Reader Writer

5. RKE

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.
