"Overflow" reading on a capacitance tester
When you connect a known good capacitor it will show a proper ESR value, so I ''think'' the meter is working properly. However when I connect to these 47uF, electrolytic capacitors it continues to read OL instead of giving me an ESR value. It is designed to work with capacitors on-board.
capacitor
Powering a 16v max capacitor, at 16v, is stressing it. Running a 20mA led at 20mA will only provide x number of hours of life, while running it at 10mA will provide y hours, where y is greatly larger than x. Derating is limited to only resistors and capacitors or it applies to ASICs also. Derating can apply to almost anything.
How Capacitors Work
Several capacitors, tiny cylindrical electrical components, are soldered to this motherboard. Peter Dazeley/Getty Images. In a way, a capacitor is a little like a battery. Although they work in completely different ways, capacitors and batteries both store electrical energy. If you have read How Batteries Work, then you know that a battery has two terminals. …
Capacitors Basics
What are capacitors? In the realm of electrical engineering, a capacitor is a two-terminal electrical device that stores electrical energy by collecting electric charges on two closely spaced surfaces, which are insulated from each other. The area between the conductors can be filled with either a vacuum or an insulating material called a dielectric.
What is a Capacitor Bank?
Basically capacitor banks reduce the phase difference between the voltage and current. On the addition of power bank, the current leads the voltage, hence the power factor angle is reduced. Reduction in power factor …
Capacitor Codes
Capacitor Codes Capacitors are labeled in a wide variety of different ways, but this handout lists the most common markings on capacitors and what they mean. Electrolytic and Tantalum capacitors often have the capacitance (in uF) and voltage (maximum allowed voltage) printed on them in human-readable form. The capacitance will usually be ...
What does the Voltage Rating on a Capacitor Mean?
It is normally recommended to give a good amount of room when choosing the voltage rating of a capacitor. Meaning, if you want a capacitor to hold 25 volts, don''t choose exactly a 25 volt-rated capacitor. Leave some room for a safety margin just in case the power supply voltage ever increased due to any reasons.

What Is ESR and Why Does It Matter? Part 1
Equivalent series resistance (ESR), also known as internal resistance, is a value representing the loss of useful energy in a simple electronic circuit consisting of a resistor and an ideal (perfect) capacitor. Technically speaking, the energy is not lost but is usually dissipated as undesirable heat. The heat is generated when electricity flows …

Normally Open Vs Normally Closed: What Do They Mean?
Normally open (NO) contacts mean that current does not flow through them in its normal state. When normally open contacts are activated they will allow current to flow through them. Normally closed (NC) contacts mean that current can flow through them when the switch or button has not been activated. When normally open contacts are …
Dissipation Factor
NPO type units (low K values) will generally measure between .1 to .5% OF at room temperature, while the General Purpose type (high K values) generally read between 1.0 to 2.5% OF at room temperature. Most electrolytic type capacitors have PF values that exceed 10% and therefore the relation OF= PF is not valid.
