ds07-10202-1e fujitsu semiconductor data sheet high-frequency resonator piezoelectric resonator (24 to 40 mhz) far family (c4 series l type) n description the c4 series (l type) resonators apply to the frequency range 24 to 60 mhz. they are fabricated on a lithium niobate (linao 3 ) substrate, producing resonators with ultra compact and superior stability due to the high electromechanical coupling coef?ient of the material. they use the third overtone resonance, so that they can oscilate at high frequency. they include two loading capacitors inside and their package are chip type for surface mount. it contributes saving space and reducing mount cost. n features high frequency (24 to 60 mhz) surface mount package (smt) suitable for the source of microcomputer clock emboss-typed pack for automatic mounting superior shock and vibration resistance, preventing damage during automatic mounting n package
