Standard atmospheric conditions 温度 Temperature 相对湿度 Relative humidity 气压 Air pressure 15°C~35°C 25%~75% 86kpa~106kpa 在进行测量之前，电容器应在测量温度下存放足够时间，以使整个电容器都达到这一温度。为此目的，规定与 试验后恢复时间同样的时间，通常是足够的。 Before the measurements are made, the capacitor shall be stored at the measuring temperature for a time sufficient to allow the entire capacitor to reach this temperature. The period as prescribed for recovery at the end of a test is normally sufficient for this purpose. 在标准大气条件下进行测量，其测量结果存在争议时应采用仲裁温度（见1.3）重复测量。 Test and measurement shall be made under standard atmospheric conditions for testing, in the event of a dispute, the measurements shall be repeated using one of the referee temperatures (as given in 1.3). 当按某一顺序进行试验时，一个试验的最后测量可以作为下一试验的初始测量。 When tests are conducted in a sequence, the final measurements of one test may be taken as the initial measurements for the succeeding test. 在测量期间，不应使电容器受到气流、阳光直射或可能引起误差的其他影响。 During measurements the capacitor shall not be exposed to draughts, direct sunlight or other influences likely to cause error. 1.2.恢复条件 Recovery conditions 除非另有规定，恢复应在试验用标准大气条件（见1.1）下进行。 Unless otherwise specified recovery shall take place under the standard atmospheric conditions for testing (1.1). 如果恢复必须在严格控制的条件下进行，应采用IEC 60068-1中5.4.1的控制条件。 If recovery under closely controlled conditions is necessary, the controlled recovery conditions of 5.4.1 of IEC 60068-1 shall be used. 除非有关规范另有规定，恢复时间应为1h～2h。 Unless otherwise specified in the relevant specification, a duration of 1 h to 2 h shall be used. 1.3.仲裁条件 Referee conditions 在仲裁情况下，应选用IEC 60068-1中5.2中规定的仲裁试验用标准大气条件。 For referee purposes, one of the standard atmospheric conditions for referee tests taken from 5.2 of IEC 60068-1, as given in table 1 below, shall be selected: 表2. 仲裁条件 Table 2.

Be sure to use a capacitor with a rated voltage range that includes these irregular voltages. 表3. 工作电压Vp-p Table 3.

Be sure to take into account the heat generated by the capacitor itself. 电容器在高频电流、脉冲电流等中使用时可能会因介电损耗发出自生热，所施加之正弦波电压的频率应低于 300kHz。 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 300kHz. 外加电压应使自生热等负荷在25℃周围温度条件下不超过20℃范围。 The applied voltage load should be such that the capacitor's self-generated heat is within 20°C in an atmosphere temperature of 25°C. 测量时应使用ø0.1mm小热容量的(K)的热电偶，而且电容器不应受到其它元件的散热或周围温度波动影响(切勿在 冷却风扇运转时进行测量。否则无法确保测量数据的精确性)。 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 (Never attempt to perform measurement with the cooling fan running. Otherwise, accurate measurement cannot be ensured.). 过热可能会导致电容器特性及可靠性下降。 Excessive heat may lead to deterioration of the capacitor's characteristics and reliability. 使用低损耗电容器之前，一定要仔细阅读第4项的说明。 Before using the low loss type ceramic capacitors, be sure to read the instructions in item 4. 4. 在施加高频和高电压过程中的负荷降低与自生热 Load reduction and self-generated heat during application of high-frequency and high-voltage 由于低损耗电容器所具有的低自生热特性，此类电容器的允许电功率一般均高于Y5P特性电容器。但是，在峰间 幅值等于电容器额定电压的高频电压条件下，当自热温度达到20℃时，电容器的功率消耗会超过其允许电功率。 Due to the low self-heating characteristics of low loss type ceramic capacitors, the allowable electric power of these capacitors is generally much higher than that of Y5P characteristic capacitors. However, in case the self-heating temperature is 20°C under a high -frequency voltage whose peak-to-peak value equals the capacitor's rated voltage, the capacitor's power consumption may exceed its allowable electric power. 因此，在将SL特性/低损耗系列电容器用在频率为1kHz或以上的高频高压电路中时，应确保包括直流偏压在内的 Vp-p值不超过表4所规定之施加电压值。同时，还应确保25℃周围温度条件下的自生热温度(电容器表面温度与电 容器周围温度之间的温度差)不超过表4所规定的温度值。 Therefore, when using the SL characteristic / low loss series in a high-frequency and high-voltage circuit with a frequency of 1kHz or higher, make sure that the Vp-p values including the DC bias, do not exceed the applied voltage value specified in Table 4. Also make sure that the self-heating temperature (the difference between the capacitor's surface temperature and the capacitor's ambient temperature) at an ambient temperature of 25°C does not exceed the value specified in Table 4.

This allowable voltage, however, varies depending on the voltage and current waveforms. 因此，您一定要确保自生热温度不高于表4所规定的温度值。 Therefore, you are requested to make sure that the selfheating temperature is not higher than the value specified in Table 4. 5. 耐电压的测试条件 Test condition for withstanding voltage 5.1.测试设备 Test equipment 交流耐压的测试设备应具有能够产生类似于50/60Hz正弦波的性能。如果施加变形的正弦波或超过规定电压值的 过载电压后，则可能会导致故障。 Test equipment for AC withstanding voltage should be used with the performance of the wave similar to 50/60Hz sine wave. If the distorted sine wave or overload exceeding the specified voltage value is applied, a defect may be caused. 5.2.电压外加方法 Voltage applied method 使用耐电压时，电容器的引线或端子应对耐电压测试设备的输出端连接牢固；然后再将电压从近零增加到测试 电压。 When the withstanding voltage is applied, capacitor's lead or terminal should be firmly connected to the output of the withstanding voltage test equipment, and then the voltage should be raised from near zero to the test voltage. 如果测试电压不从近零逐渐提高而是直接施加在电容器上，则施加时应包含过零点。测试结束时，测试电压应 降到近零；然后再将电容器引线或端子从耐电压测试设备的输出端取下。 If the test voltage without the raise from near zero voltage would be applied directly to capacitor, test voltage should be applied with the zero cross. At the end of the test time, the test voltage should be reduced to near zero, and then capacitor's lead or terminal should be taken off the output of the withstanding voltage test equipment. 电压正弦波 如果测试电压不从近零逐渐提高而是直接施加在电容器上，则可能会出现浪涌电 Voltage sine wave 压，从而导致故障。 If the test voltage without the raise from near zero voltage would be applied directly to capacitor, the surge voltage may arise, and therefore, a defect may be caused. 0V 过零点是指电压正弦通过0V的位置。参见右图。 过零点 ZERO CROSS is the point where voltage sine wave passes 0V.

Be sure to provide an appropriate fail-safe function like a fuse on your product if failure would result in an electric shock, fire or fuming. 7. 电容器容量变化 Capacitance change of capacitors 电容量可能会因环境温度或外加电压而发生轻微变化。若要将其用于严格的时间常数电路，请与我公司联系。 Capacitance might change a little depending on a surrounding temperature or an applied voltage. Please contact us if you use for the strict constant time circuit. Hi-k类电容器具有老化特性；因此，电容器若长时间使用，其电容量会逐渐降低。而且，电容量还可能会因环境 温度或外加电压而发生巨大变化。所以不适合用于时间常数电路。 Hi-k type ceramic 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. So, it is not likely to be suitable for use in a constant time circuit. 若需详情，请与我公司联系。 Please contact us if you need detailed information. 8. 使用设备进行性能检查 Performance check by equipment 使用电容器之前，请先检查设备的性能和特性没有问题。 Before using a capacitor, check that there is no problem in the equipment's performance and the specifications. 一般而言，Hi-k类电容器的电容量具有电压相关特性和温度相关特性。所以，其电容值可能会随设备的工作条件 而发生变化。因此，一定要确认仪器接收性能对电容器的静电容量值变化的影响，如漏电流和静噪特性。 Generally speaking, Hi-k type ceramic capacitors have voltage dependence characteristics and temperature dependence characteristics in capacitance. So, the capacitance value may change depending on the operating condition in the equipment. Therefore, be sure to confirm the apparatus performance of receiving influence in the capacitance value change of a capacitor, such as leakage current and noise suppression characteristic. 此外，必要时还要检查电容器在设备中的防电涌性能，因为通过电路的感应，浪涌电压可能会超过规定值。 Moreover, check the surge-proof ability of a capacitor in the equipment, if needed, because the surge voltage may exceed specific value by the inductance of the circuit. 贮存条件 STORAGE ENVIRONMENT 电容器绝缘包封层不是完美的密封形式，因此，请勿将电容器存放在腐蚀性气体中，尤其是存在氯气、硫气、酸、 碱、盐等场所，同时应防潮。 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. 电容器应存放在温度及相对湿度分别不超出-10°C～40°C及15%～70%范围的场所。请在6个月内使用电容器。 Store the capacitors where the temperature and relative humidity do not exceed -10 to 40 degrees centigrade and 15% to 70%. Use capacitors within 6 months after delivered. 长时间保管（6个月以上）时，使用时请确认电容器的电容量及可焊性。 Before using the capacitors that has been stored for a long period (6 months or longer), confirm the capacitance and solderability.
