!Note
CFWLA_Y series are high selectivity ceramic filters,
which consist of 6 ceramic elements connected in a
ladder form.
Most suitable for digital communications and mobile
telephones because of their improved GDT
characteristics.
1. High selectivity
2. A variety of bandwidths are available
3. Excellent GDT characteristics are available within
4. Easily mounted on a printed circuit board
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 should be an integral multiple of the "Minimum Quantity" shown in package page in this catalog.
