1. When using chip-type ceramic resonator devices, pay special attention to failsafe features. It's best to add protection or flame-retardant circuitry to prevent malfunction and damage. Also, pay attention to the device's operating temperature range, which must not exceed the specified operating temperature range.
2. When using ceramic resonators, pay attention to fluctuations in their oscillation frequency. The oscillation frequency of some active crystal oscillators can drift depending on the integrated circuit (IC) and the capacitance of the external capacitors used. This can cause periodic oscillation or even cessation of oscillation, so be mindful of this during use.
3. Stray capacitance and insulation resistance on printed circuit boards can cause ceramic resonators to exhibit abnormal behavior, such as cessation of oscillation or high-order harmonic oscillation.
4. Generally speaking, ceramic resonators exhibit excellent resonance. If abnormal oscillation occurs, pay special attention to environmental conditions. Furthermore, when using a ceramic resonator, two selected capacitors must be added to construct the oscillation circuit, and these capacitor values must meet certain requirements. The above explains the precautions for using ceramic resonators. When using ceramic resonators, you must pay special attention to these aspects, as they are closely related to safety. Generally speaking, flow soldering is not suitable for chip-type ceramic resonators. Ultrasonic welding and ultrasonic cleaning are also best avoided to avoid electrical problems.
