7. CAUTIONS FOR USE
7-1. Resonator might be damaged when an excess stress is applied.
7-2. Cleaning or washing of the component is not acceptable due to non sealed construction.
Cleaning conditions, such as kinds of cleaning solvents, immersion time and temperatures
etc, after soldering shall be checked by experiments before production.
7-3. Conformal coating of the component is acceptable. However, the resin material, curing
temperature, and other process conditions should be evaluated to confirm stable electrical
characteristics are maintained.
7-4. Irregular or stop oscillation may occur under unmatched circuit conditions. And it shall be
noted that oscillating frequencies of the Ceramics Resonator may drift depending on IC applied
(the type names, the manufacturer) and capacitance of external capacitors(C1,C2) and the
circuit design in figure 1.
