Here are three top manufacturers that offer high-quality capacitors: Manufacturer D is a well-known brand that produces capacitors with exceptional quality. Their products are reliable and durable, making them ideal for various applications.
Manufacturer A is a leading capacitor manufacturer that has been in the industry for over 50 years. They offer a wide range of capacitors, including ceramic, tantalum, and aluminum electrolytic capacitors. Their products are used in various industries, such as automotive, telecommunications, and consumer electronics.
Manufacturer G has been a leader in the industry for years and has continued to innovate with their latest line of capacitors. Their newest product features a high energy density, which allows for a smaller form factor without sacrificing performance.

Unlike resistors, capacitors use a wide variety of codes to describe their characteristics. Physically small capacitors are especially difficult to read, due to the limited space available for printing. The information in this article should help you read almost all modern consumer capacitors. Don't be surprised if your information is. Inspect the surface of the capacitor and look for any numbers printed on it. The numbers are usually expressed as a three-digit value. The numeric value directly represents the capacitance. [pdf]
To read a large capacitor, first find the capacitance value, which will be a number or a number range most commonly followed by µF, M, or FD. Then look for a tolerance value, typically listed as a percentage. Next, check the voltage rating, which is usually listed as a number followed by the letters V, VDC, VDCW, or WV.
Some small capacitors are marked with codes like 1n0. The digits are the values before and after the decimal point and the the character tells you the dimension; so the example given is 1.0 nF (nano-Farad). Look for a letter code. Some capacitors are defined by a three number code followed by a letter.
A: Capacitor code values are used to represent the capacitance value of a capacitor component. Capacitors are electronic components that store and release electrical energy. The code values help in identifying the capacitance value of a capacitor without having to write the full value in Farads. Q: How are capacitor code values expressed?
Numerical Markings One of the most common formats for capacitor markings is the numerical code. This is typically a series of three or four digits, which represent the capacitance value and sometimes the tolerance. Three-digit code: The first two digits represent the significant figures, and the third digit indicates the number of zeros to add.
The capacitance is this number of picoFarads (pF). If we call the digits ABC, the capacitance is given by the formula (AB * 10C) pF. For example, a capacitor that reads 224 is 22 * 104 pF = 220,000 pF = 220 nF = 0.22 uF. The number followed by a letter indicates the capacitance and tolerance of the cap, as in the previous case.
The various parameters of the capacitors such as their voltage and tolerance along with their values is represented by different types of markings and codes. Some of these markings and codes include capacitor polarity marking; capacity colour code; and ceramic capacitor code respectively.
