Caution No. Process 1 Operating Condition (Storage, Transportation) Condition 1-1. Storage 1) The capacitors must be stored in an ambient temperature of 5 to 40°C with a relative humidity of 20 to 70%RH. The products should be used within 6 months upon receipt. 2) The capacitors must be operated and stored in an environment free of dew condensation and these gases such as Hydrogen Sulphide, Hydrogen Sulphate, Chlorine, Ammonia and sulfur. 3) Avoid storing in sun light and falling of dew. 4) Do not use capacitors under high humidity and high and low atmospheric pressure which may affect capacitors reliability. 1-2. Handling in transportation In case of the transportation of the capacitors, the performance of the capacitors may be deteriorated depending on the transportation condition. (Refer to JEITA RCR-2335B 9.2 Handling in transportation) 2 Circuit design Caution 2-1. Operating temperature Operating temperature should be followed strictly within this specification, especially be careful with maximum temperature. 1) Do not use capacitors above the maximum allowable operating temperature. 2) Surface temperature including self heating should be below maximum operating temperature. (Due to dielectric loss, capacitors will heat itself when AC is applied. Especially at high frequencies around its SRF, the heat might be so extreme that it may damage itself or the product mounted on. Please design the circuit so that the maximum temperature of the capacitors including the self heating to be below the maximum allowable operating temperature. Temperature rise at capacitor surface shall be below 20°C) 3） The electrical characteristics of the capacitors will vary depending on the temperature. The capacitors should be selected and designed in taking the temperature into consideration. 2-2. Operating voltage 1) Operating voltage across the terminals should be below the rated voltage. When AC and DC are super imposed, V0-P must be below the rated voltage. ——— (1) and (2) AC or pulse with overshooting, VP-P must be below the rated voltage. ——— (3), (4) and (5) When the voltage is started to apply to the circuit or it is stopped applying, the irregular voltage may be generated for a transit period because of resonance or switching. Be sure to use the capacitors within rated voltage containing these Irregular voltage.

The capacitors should be selected and designed in taking the voltages into consideration. 2-3. Frequency When the capacitors (Class 2) are used in AC and/or pulse voltages, the capacitors may vibrate themselves and generate audible sound. 3 Designing Alumina Substrate The amount of glue at the terminations has a direct effect on the reliability of the capacitors. 1) The greater the amount of glue with low thickness of land, the higher risk of electrical connection by conductive glue. Design of land and the amount of glue must be considered well. 2) Avoid using common land for multiple terminations and provide individual land for each terminations. 4 Mounting 4-1. Stress from mounting head 1) If the mounting head is adjusted too low, it may induce excessive stress in the chip capacitor to result in cracking. Please take following precautions. 2) Adjust the bottom dead center of the mounting head to reach on the Alumina substrate surface and not press it. 3) Adjust the mounting head pressure to be 1 to 3N of static weight. 4-2. Amount of conductive glue Excessive glue will make a electrical connection under the chip. In sufficient glue may detach the capacitor from the Alumina substrate. Excessive glue Electrical connection will be made under the chip. Adequate Low robustness may cause contact failure or chip capacitor comes off the Alumina substrate. Insufficient glue — 12 — No. 5 Process Coating and molding of the Alumina substrate Condition 1) When the Alumina substrate is coated, please verify the quality influence on the product. 2) Please verify carefully that there is no harmful decomposing or reaction gas emission during curing which may damage the chip capacitors. 3) Please verify the curing temperature. 6 Handling of loose chip capacitors 1) If dropped the chip capacitors may crack. Once dropped do not use it. Especially, the large case sized chip capacitors are tendency to have cracks easily, so please handle with care. Crack Floor 2) Piling the Alumina substrate after mounting for storage or handling, the corner of the Alumina substrate may hit the chip capacitors of another board to cause crack. P.C.board Crack 7 Capacitance aging The capacitors (Class 2) have aging in the capacitance. They may not be used in precision time constant circuit. In case of the time constant circuit, the evaluation should be done well. 8 Estimated life and estimated failure rate of capacitors As per the estimated life and the estimated failure rate depend on the temperature and the voltage. This can be calculated by the equation described in JEITA RCR-2335B Annex 6 (Informative) Calculation of the estimated life time and the estimated failure rate. ( Voltage acceleration coefficient : 3 multiplication rule, Temperature acceleration coefficient : 10°C rule) The failure rate can be decreased by reducing the temperature and the voltage but they will not be guaranteed. — 13 — No. 9 Process Others Caution Condition The products listed on this specification sheet are intended for use in general electronic equipment (AV equipment, telecommunications equipment, home appliances, amusement equipment, computer equipment, personal equipment, office equipment, measurement equipment, industrial robots) under a normal operation and use condition.
