How to identify the multiplayer ceramic chip capacitors on the PCB?

If it is a single chip capacitor, use a capacitance tester to measure its capacity. No identification can be used to identify the series type by measuring the length and width of the capacitor. A detailed brand or the like can find the same comparison.

Multiplayer ceramic multiplayer ceramic multiplayer ceramic chip capacitors are called: multilayer (laminate, laminated) chip ceramic capacitors, also known as multiplayer ceramic multiplayer ceramic multiplayer ceramic chip capacitors, film capacitance. English full name: Multi-layerceramiccapacitors. English abbreviation: MLCC. Multiplayer ceramic multiplayer ceramic multiplayer ceramic chip capacitors have two dimensions to indicate the method. One is in inches and the other is in millimeters. For example, 0402 series multiplayer ceramic multiplayer ceramic multiplayer ceramic chip capacitors, 04 means the length is 0.04 inches, and 02 means the width is 0.02 inches. .

Capacitance: Can be divided into non-polarity and polarity. Non-polarity capacitors are the most common in the following two types of packages.

The chip package mainly includes: 0201 1/20W 0402 1/16W 0603 1/10W 0805 1/8W 1206 1/4W

The corresponding relationship between the external dimensions of the capacitor and the package is: 0402=1.0x0.5 0603=1.6x0.8 0805=2.0x1.2 1206=3.2x1.6 1210=3.2x2.5 1812=4.5x3.2 2225=5.6 The size of the x6.5 capacitor itself is not related to the package method. The package is related to the nominal power. The length and width are usually expressed in millimeters. However, the type is an indication of the selected inch. Select the appropriate package list to see the PCB space first, is not able to put down this equipment. Generally speaking, large packaged equipment will be relatively inexpensive, and small packaged equipment will be more expensive due to processing progress. It may be more expensive, and then the large package capacitor voltage value will be higher than the small package capacitor capacity voltage value. These are selected according to the needs of practice. A small packaged meta-device will have a higher placement request, such as the accuracy of an SMT machine. If the circuit board inside the mobile phone, due to space is limited, the operating voltage is low, you can use 0402 resistors and capacitors, and large-capacity tantalum capacitors are mostly 3216 and other large packages.
