Built-in load capacitors are included in same miniature package. Miniaturized packaging technology results in very small mainstream packages. Good Frequency Accuracy and Good Stability Over Temperature.The power consumption of amplifiers fabricated in CMOS is largely proportional to the operating frequency and can be expressed as a power-dissipation capacitance value.Ĭeramic circuits typically specify larger load capacitance values than crystal circuits, and draw still more current than the crystal circuit using the same amplifier. The power consumption of discrete component crystal-oscillator circuits is primarily determined by the feedback-amplifier supply current and by the in-circuit capacitance values used. Power consumption is another important consideration of oscillator selection. The majority of clock sources for microcontrollers can be grouped into two types: those based on mechanical resonant devices, such as crystals and ceramics, and those based on electrical phase-shift circuits such as RC (resistor, capacitor) oscillators.Ĭeramic and crystal resonator-based oscillators (mechanical) typically provide very high initial accuracy and a moderately low temperature coefficient.

Avoid resin coating or potting for humidity protection because it could deteriorate the resonator's performance characteristics.ĭownload Applications & Notice in PDF file.

Avoid washing in water because it could deteriorate the resonator's performance characteristics.

Ultrasonic Cleaning and Ultrasonic Welding should not be used on resonators to avoid possible damage.

Please do not apply excess mechanical stress to the component and lead terminals at soldering.Flow Soldering should not be used to solder resonators.In automated mounting of The resonators on printed circuit boards, any bending, expanding and pulling forces or shocks to the resonator should be kept to a minimum to prevent electrical failures and/or mechanical damage to the devices. Abnormal Mechanical Stressesīnormal or excess mechanical stresses such as vibration or shock should be avoided when handling or storing resonators to prevent damage and cracking. Voltage spikes and electrostatic discharges may cause damage/malfunction or failures of the resonators. Overvoltage Spikes & Electrostatic Discharges These factors should be taken into consideration when designing the circuit. Stray capacitances and insulation resistances on printed circuit boards may cause abnormal oscillation or stoppage of oscillation. Spurious oscillations or stoppage of oscillation may occur depending on the circuit design (IC used, frequency characteristics of the IC, supply voltage etc.) and/or environmental conditions. The resonators are always accompanied by spurious resonances. When using The resonators, it is recommended that you build a protective failsafe circuit into your design to prevent equipment damage in the event that the resonator malfunctions or fails. When you require exact oscillation frequency in your application, we can adjust it with your specified circuit on request. There could be slight shift in frequency other types of IC are used. Token standard resonator is adjusted with our standard measuring circuit.

Oscillating frequency may drift depending upon the controlling IC and/or external capacitors C 1 and C 2 used in the circuit design. The resonators should not be operated beyond the Operating Temperature Range specified in the catalog.
