NEC evaluates PC1862 using resonators which are shown below in design and development process.
If the different product is used as a resonator, electrical specification value described in this document is not assured.
And when connecting resonator to external circuit, there is need to consider temperature specification, voltage
Use the resonators which are shown below when you design circuit.
