Hi guys,

I am using an LCR meter with a test voltage of 0.3Vrms. Available test frequency is only 100Hz. But the capacitor that I want to test is specified at 120Hz.

Although this seems to be pretty close, I just want to know how much would be the difference if the LCR meter could read it at 120Hz.

Do you guys know any formula or correction factor that I can use to compute the capacitance at 120Hz with the values I am getting at 100Hz?

Also if you could share how does the LCR meter measure capacitance and dissipation factor (I mean does...

Re: Cap rated voltage

Thank you very much sofTest! I think that's the answer I was looking for.

I was googling and had no luck finding that website, I was hoping you could post it here.

Re: Cap rated voltage

I mean, a means for you to check if the cap is in tune with the data table.

For example, I have a 47uF/50V cap. Can I hook the cap directly to a 50V DC power supply and measure if the capacitance is not changing? Is the way I measure capacitance acceptable? If the capacitance remain unchange, can I say that the cap is in tune with the datasheet?

Hi Guys,

How do you test for the capacitor's rated voltage?

Hi guys. A question pop-up in my prof's IM. In his words he asked,

"Does the difference in tantalum size affect the endurance of tantalum cap performance in the long term?"

So basically he is asking which tantalum cap would die out first, the small or the big one? I think the smaller one would give in first as time passes due to the dielectric being heated up much easily. I don't know if there's a study about this, but I was hoping you can give your thoughts on this... Thanks
