Part of the large portfolio of KYOCERA AVX crystal units, the CX2016FB and CX3225FB support the frequencies most widely required in consumer and industrial circuits.

KYOCERA AVX supplies miniature crystal units which offer high timing accuracy across a wide operating-temperature range.

 

Supporting many of the most commonly used frequencies, the CXxxxxFB series crystal units are a particularly attractive low-cost option for building a timing circuit. The CX2016FB is supplied in a package with a footprint of 2.0 mm x 1.6 mm. Designers can order a CX2016FB product with a frequency output of 24 MHz, 25 MHz, 26 MHz, 27 MHz, 32 MHz, 3.84 MHz, 40 MHz, 48 MHz, or 50 MHz.

 

The CX3225FB units in a 3.2 mm x 2.5 mm package also support these frequencies, and can additionally produce a 16 MHz or 20 MHz output.

 

Available with load capacitance ratings of 6 pF, 7 pF, 8 pF, or 10 pF, these CX devices are suitable for consumer or industrial applications.
