CFXC_ series are very small and high-efficiency
surface mount, ladder type 450/455 kHz ceramic filters
"CERAFIL" for IF section.
Compared to our previous compact surface mounted
6-element product, this ceramic filter has been
significantly downsized to approximately one-third
the original volume and reduced to less than 2 mm in
height.
As for electrical performance, this product, which
consists of 4 elements, provides stop band attenuation
equivalent to that of our previous 6-element product.
The input/output impedance characteristics are also
equivalent to those of the previous product, and
spurious responses in the vicinity of the passing band
can now be eliminated. This allows mobile
telecommunications equipment manufacturers to easily
design the periphery of the IF section and thus
greatly enhance the interference suppression
capability of the equipment.In addition, this ceramic
filter provides flatter group delay time
characteristics than the previous product, and will
effectively work as a component for data transmission
in digital mobile telecommunications systems.

■ Features
1. Compact, thin, and lightweight.
(Size : CFXCA450KBFA-R1: 6.5x6.5x1.9mm
CFXCD450KCFA-R1: 5.2x3.8x1.4mm
Weight: CFXCA series: 225mg
CFXCD series: 75mg)
2. Out-of-band attenuation is increased and spurious
responses are greatly decreased.
3. Group delay time characteristics are flattened.
4. Surface mountable, and reflow soldering can be used
for mounting.
■ Applications
1. IF filters for PDCs.
2. IF filters for various types of pagers.
3. IF filters for various types of analog and digital
cellular telephones.
4. IF filters for radio communication circuits
applicable for PDA or PCMCIA.
5. IF filters for other general mobile wireless
equipment

Ceramic Filters (CERAFILr)/Ceramic Discriminators for Communications Equipment
6.5±0.3
The CFUCF series comprises small, high performance,
thin (4.0mm) filters consisting of 4 ceramic elements.
The filters exhibit an extremely flat GDT
characteristic.
The filters are recommended for digital
communication applications and are perfect in hand
held cellular phones, etc.

1. The component will be damaged when an excessive
stress is applied.
2. Use coupling capacitors to prevent applying D.C.
voltage between input-ground, output-ground of
"CERAFIL" as D.C. current may harm the component.
3. Do not clean or wash the component as it's not
hermetically sealed.
4. Do not apply conformal coating onto the component
as it's not hermetically sealed.
5. Do not use strong acidity flux, more than 0.2wt%
chlorine content, in re-flow soldering.
■ SFPCA/CFUCG/CFUCF Series Notice (Handling)
1. The component will be damaged when an excessive
stress is applied.
2. Use coupling capacitors to prevent applying D.C.
voltage between input-ground, output-ground of
"CERAFIL" as D.C. current may harm the component.
3. In the case that the component is cleaned, confirm
no reliability degradation is created.
4. In case of covering filter with over coat,
conditions such as material of resin, cure
temperature, and so on should be evaluated well.

5. Do not use strong acidity flux, more than 0.2wt%
chlorine content, in re-flow soldering.
6. The product, packed in the moisture-proof bag
(dry pack), is sensitive to moisture. The following
treatment is required before applying re-flow
soldering, to avoid package cracks or reliability
degradation caused by thermal stress. When unpacked,
store the component in an atmosphere of below 25 C.
and below 65% R.H., and solder within 48 hours.
