6.1.2: Capacitance and Capacitors

For large capacitors, the capacitance value and voltage rating are usually printed directly on the case. Some capacitors use "MFD" which stands for "microfarads". While a capacitor color code exists, rather like the resistor color code, it has generally fallen out of favor. For smaller capacitors a numeric code is used that echoes the

Dielectric Material in Capacitors: Understanding Their

Tantalum capacitors are like electrolytic capacitors in that it has a metal plate as one of their electrodes, but instead of an oxide layer, the dielectric material is tantalum pentoxide. These capacitors are used where high capacitance and stability are important. Due to their high capacitance, tantalum capacitors can be found in power supplies and audio equipment.

6 FAQs about [What are the indoor requirements for capacitors ]

How to choose a capacitor?

safety and quality should be the top priori-ties when a capacitor is selected. This is why we urgently recommend the use of capacitors with appropriate internal pro-tective devices. 2. Before designing the application, capaci-

How much ampacity should a capacitor have?

The ampacity of conductors that connect a capacitor to the terminals of a motor or to motor circuit conductors shall not be less than one-third the ampacity of the motor circuit conductors and in no case less than 135 percent of the rated current of the capacitor. Overcurrent Protection.

What is a power capacitor?

describe the state of technology which must as a rule be adhered to in all relevant contracts for goods and services. II. General safety rules Since power capacitors are electrical energy storage devices, they must always be handled with caution.

Should a capacitor test be based on a standard?

Even if the test based on the capacitor standard is passed, this does not ensure comprehensive protection against all pos-sible overloading. Currently, a number of customers are requesting special tests on unprotected capacitors with extreme overvoltages and temperatures to prove safe capacitor per-formance.

What should not be used in a capacitor circuit?

Manual means of switching or connecting the discharge circuit shall not be used. Conductors. Ampacity. The ampacity of capacitor circuit conductors shall not be less than 135 percent of the rated current of the capacitor.

Can a capacitor be stored in a corrosive environment?

Capacitors must never be stored or used Capacitors may not be stored or operated in corrosive atmospheres, particularly not salts, organic solvents or similar substan-ces are present. In dust and dirt-prone environments, regu-
