穿心电容/穿芯电容/铝电解电容器的指标和选型
1、标称电容量(NominalCapacitance)指在测试频率120Hz时所测得之电容量,电容量与金属(铝箔)相对面积及介质常数成正比,与两极间距离成反比。C=εA/d
2、电容量误差(Capacitance Tolerance)K(&plu***n;10%), M(&plu***n;20%), V(-10~+20%)
3、额定工作电压(Rated Working Voltage)(WV)在***高工作温度下,电解电容可以承受之***高直流电压。
4、突波电压(Surge Voltage)(SV)在***高工作温度下,电解电容器可以承受之相当瞬间***高峰值电压。
5、工作温度范围(OperatingTemperatureRange)25~+85℃ ,- 40~+ 85℃ , - 25~+105℃ , - 40~+105℃
6、等效串联电阻(EquivalentSeriesResistance)(ESR)(电极电阻+电解质电阻+介质损失)。ESR= DF/2πf C
7、泄漏电流(Leakage Current)(LC)电容器施加直流电压,经规定时间后继续流通之***大直流电流。I≦0.01CV or 3μA Whichever isgreater(上示公式须视不同系列产品而定。)
8、涟波电流(Ripple Current)(RC)在***高工作温度及120Hz(or100KHz)频率下,电解电容器可以承受之***高交流电流。 (温度/频率补正系数)
9、低温特性(LowTemperatureCharacteristics)是指在-25℃/-40℃时,与在常温20℃之***大阻抗比。
10、尺寸大小 例如:Φ 4X7 ,Φ 5X11..........
