Ceramic resonators (CERALOCK®) are made of high stability piezoelectric ceramics that function as a mechanical resonator. This device has been developed to function as a reference signal generator and the frequency is primarily adjusted by the size and thickness of the ceramic element. With the advance of the IC technology, various equipment may be controlled by a single LSI integrated circuit, such as the one-chip microprocessor. CERALOCK® can be used as the timing element in most microprocessor based equipment. In the future, more and more applications will use CERALOCK® because of its high stability nonadjustment performance, miniature size and cost savings. Typical applications include TVs, VCRs, automotive electronic devices, telephones, copiers, cameras, voice synthesizers, communication equipment, remote controls and toys.

• High stability of oscillation frequency: Oscillation frequency stability is between that of the quartz crystal and LC or RC oscillation circuits. The temperature coefficient of quartz crystal is 10⁻⁶/℃ maximum and approximately 10⁻³ to 10⁻⁴/℃ for LC or RC oscillation circuits. Compared with these, it is 10⁻⁵/℃ at -20 to +80℃ for ceramic resonators.
• Small configuration and light weight: The ceramic resonator is half the size of popular quartz crystals.
• Low price, non-adjustment: CERALOCK® is mass produced, resulting in low cost and high stability. Unlike RC or LC circuits, ceramic resonators use mechanical resonance. This means it is not basically affected by external circuits or by the fluctuation of the supply voltage. Highly stable oscillation circuits can therefore be made without the need of adjustment.
