When the voltage is applied to the circuit, starting or stopping may generate an irregular voltage for a transit period because of resonance or switching. Be sure to use a capacitor with a rated voltage range that includes these irregular voltages. (2) Operating Temperature and Self-generated Heat Keep the surface temperature of a capacitor below the upper limit of its rated operating temperature range. Be sure to take into account the heat generated by the capacitor itself. When the capacitor is used in a high frequency current, pulse current or similar current, it may self-generate heat due to dielectric loss. The frequency of the applied sine wave voltage should be less than 100kHz. The applied voltage load should be such that the capacitor's self-generated heat is within 20°C at an atmosphere temperature of 25°C. When measuring, use a thermocouple of small thermal capacity-K of ø0.1mm in conditions where the capacitor is not affected by radiant heat from other components or surrounding ambient fluctuations. Excessive heat may lead to deterioration of the capacitor's characteristics and reliability. (Never attempt to perform measurement with the cooling fan running. Otherwise, accurate measurement cannot be ensured.) (3) Fail-Safe It should be assumed that if the capacitor fails, it will fail in short circuit mode. Be sure to provide an appropriate fail-safe function, like a fuse in your circuit, if failure would cause an electric shock, fire or fumes. (4) Operating and storage environment The insulating coating of capacitors does not form a perfect seal; therefore, do not use or store capacitors in a corrosive atmosphere, especially where chloride gas, sulfide gas, acid, alkali, salt or the like are present, and avoid exposure to moisture. Before cleaning, bonding or molding this product, verify that these processes do not affect product quality by testing the performance of a cleaned, bonded or molded product in the intended equipment. Store the capacitors where the temperature and relative humidity do not exceed 35°C and 75%RH. Use capacitors within 12 months. (5) Vibration and impact Do not expose a capacitor or its leads to excessive shock or vibration during use. - 31 - HDC Series - High Voltage Ceramic Disc Capacitor Holy Stone (6) Soldering When soldering this product to a PCB/PWB, do not exceed the solder heat resistance specification of the capacitor. Subjecting this product to excessive heating could melt the internal solder joint and may result in thermal shock that can crack the ceramic element. When soldering capacitors with a soldering iron, it should be performed in following conditions. Temperature of iron-tip: 400 degrees C. max. Soldering iron wattage : 50W max. Soldering time : 3.5 sec. max. Failure to follow the above cautions may result, in worst case, in short circuit and cause fuming or partial dispersion when the product is used. (7) Cleaning (ultrasonic cleaning) To perform ultrasonic cleaning, observe the following conditions. Rinse bath capacity : Output of 20 watts per liter or less. Rinsing time : 5 min. maximum. Do not vibrate the PCB/PWB directly. Excessive ultrasonic cleaning may lead to fatigue failure of the lead wires. (8) Rating Capacitance change of capacitor (a). Class 1 series (Temp. Char. SL、NP0) Capacitance might change a little depending on the surrounding temperature or an applied voltage. Please contact us if you intend to use this product in a strict time constant circuit. (b). CLASS 2 Series (Temp. Char. X7R,Y5S,Y5P,Y5U and Y5V) Capacitors have an aging characteristic, whereby the capacitor continually decreases its capacitance slightly if the capacitor is left on for a long time. Moreover, capacitance might change greatly depending on the surrounding temperature or an applied voltage. Therefore, it is not likely to be suitable for use in a time constant circuit.
