Chip capacitors are passive integrated circuit (IC) components that store electrical energy. Chip capacitors are simply capacitors manufactured as integrated circuit (IC) devices, also known as chips or microchips. They are typically square or rectangular, with the length and width of the device determining its power rating.
In addition to the external visual characteristics, quality standards for internal microstructure of the chip capacitor are also applicable, as viewed on polished cross sections of capacitor samples. Units are sectioned along the long and short dimension of the capacitor to provide two edge views of the internal electrodes and terminals.
After describing high reliability testing in our previous article, let’s discuss visual standards for chip capacitors. Multilayer ceramic capacitors (MLCCs) must possess fine workmanship and physical integrity, so visual inspection of the product is performed at 20X magnification to check for defects in the capacitor body and end metallization.
The most commonly used ceramic capacitors in modern electronics are muli-layer chip capacitor (MLCC) and ceramic disc capacitor. MLCC are made in SMD (surface-mounted) technology and is widely used due to its small size. Typical values of capacitance ranging between 1nF and 1µF, although values are up to 100µF.
Capacitors are divided into two mechanical groups: Fixed-capacitance devices with a constant capacitance and variable capacitors. Variable capacitors are made as trimmers, that are typically adjusted only during circuit calibration, and as a device tunable during operation of the electronic instrument. The most common group is the fixed capacitors.
Irregularities in the construction of the chip capacitor do not necessarily affect the mechanical or electrical integrity of the device, but may be of concern in high reliability applications. The following is a compilation of structural irregularities according to the EIA 469: Figure 2. Microstructure defects
Capacitor types
Different types are used depending on required capacitance, working voltage, current handling capacity, and other properties. While, in absolute figures, the most commonly manufactured capacitors are integrated into dynamic random-access memory, flash memory, and other device chips, this article covers the discrete components.

Part 5: The Technological Innovations in Multilayer Ceramic Chip Capacitors
In the early 1980s, a chip capacitor in the "3216" form factor (3.2 by 1.6 mm) had a capacitance of 0.1 µF, but that figure has reached 100 µF today—a thousand-fold increase. This matches electrolytic capacitors, which are characterized by high capacitance. A comparison at the same capacitance shows that miniaturization has also progressed considerably. For example, a 0.1 …
