Confirm the reliability of washing and decide the dry conditions so that washing solvent is not to be remained inside the product after washing. Do not apply electricity to the product nor use the product itself until the drying is fully completed. In case of using them for an AC circuit, abnormal phenomena like oscillation etc. occasionally happen as they have an inductance or a parasitic capacitance because of their wiring structures. Use them by taking the dispersion of constants of other components into the consideration. Specifications given herein may be changed at any time without prior notice.
