FUJITSU SEMICONDUCTOR DATA SHEET DS07-10202-1E High-Frequency Resonator Piezoelectric Resonator (24 to 40 MHz) FAR Family (C4 Series L Type) DESCRIPTION The C4 series (L Type) resonators apply to the frequency range 24 to 60 MHz. They are fabricated on a lithium niobate (LiNaO3) substrate, producing resonators with ultra compact and superior stability due to the high electromechanical coupling coefficient 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. 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 PACKAGE FAR Family (C4 series L type) STANDARD CHARACTERISTICS Series C4 Series Parameter Material Lithium Niobate (LiNbO3) Frequency Standard frequency Remarks 24 to 40 MHz See " Standard Frequency" Initial frequency deviation Within 0.5% (M) Temperature characteristic (-30C to +85C) Within 0.5% Reference temperature: +25C 208 pF (standard) Capacity of built-in capacitor The 0.3% (K) version can also be produced. 104 pF are also available.

(Symbol: 2) Note: Fujitsu can also develop applicable device in addition to standard devices if it's oscillation frequency is from 24 to 60 MHz. NOTES ON USE * Handle carefully * Solder under the following conditions. 5 seconds max. at 230C (PCB) Recommended preheating is 150C for one minute in order not to apply extreme heat to the resonator. * Avoid extreme fluctuations in temperature. * There is no specific direction in resonator mounting. * Oscillation data should be examined when used in oscillation circuit with micon or other ICs. * This is for reflow solder, not for flow solder. 3 FAR Family (C4 series L type) PART NUMBERING SYSTEM FAR -- C 4 C L -- (1) (2) (3) -- (4) -- (5) (6) (7) (8) (9) (1) Series Series Single crystal Capacitator C4 LiNbO3 With built-in capacitator (2) Package Type Specification Type C CHIP (3) Package Type Specification Size L 5.0 x 4.0 x 1.6 (4) Frequency See " Standard Frequency."
