The six points you need to know about patch capacitors

1. What is capacitance?

A patch capacitor is a capacitor material. Chip capacitor full name: multilayer (laminated, laminated) chip ceramic capacitor, also known as chip capacitor, chip capacity. The chip capacitance is expressed in two ways, one in inches and one in millimeters.

A capacitor, as the name suggests, is a "vessel for charging," a device that holds an electric charge. Name: capacitor.

2. Chip capacitance parameters

C: Capacitance value (unit: F)

ε : vacuum dielectric ratio (8.84´10-12 F/m)

K: relative dielectric constant

S: effective area (m2)

d: dielectric layer thickness (m)

3. Structure of capacitor

4. Manufacturing process of patch capacitor

5. Chip capacitor components

The patch capacitor consists of electronic ceramic medium, nickel inner electrode (copper inner electrode), copper end electrode, electroplated nickel, electroplated tin, etc. None of these components contain Rohs limited substances, fully in line with the EU environmental Rohs provisions.

6. Five performance indexes of capacitors

Volume: represents the length * width * height of the capacitor

Capacity: The capacity of a capacitor indicates its capacity to store electrical energy.

Voltage resistance: The maximum DC operating voltage that a capacitor can withstand

Gear position: indicates the precision of the capacitor

Material: represents the filling medium of the capacitor
