Structure

A 104J 250V film capacitor usually has a layered structure consisting of two metalized films that are separated by a thin dielectric layer. The metalized films act as electrodes, and the dielectric layer between them serves as an insulator. The dielectric material used in the capacitor is usually polypropylene, polyester, or polycarbonate.

The capacitor is housed in a plastic casing, which provides mechanical protection and electrical insulation. The leads of the capacitor are typically made of tinned copper wire, which is attached to the electrodes through a metallization process.

The layered structure of the film capacitor provides several advantages, such as high insulation resistance, low equivalent series resistance (ESR), low equivalent series inductance (ESL), and high ripple current handling capacity. These characteristics make film capacitors ideal for high-frequency applications, power electronics, and audio equipment.

FAQs

What is a 104J capacitor?

A 104J capacitor is a capacitor with a capacitance value of 0.1 µF and a tolerance of ±5%. The “J” in the part number represents the dielectric material, which is polypropylene film.

What is the difference between K and J capacitor?

The difference between K and J capacitors is the dielectric material used. K capacitors use polyester film as the dielectric material, while J capacitors use polypropylene film. Polypropylene film is generally considered to have better electrical properties than polyester film.

What is the value of 104 capacitor in uF?

The value of a 104 capacitor is 0.1 µF. The first two digits of the part number represent the significant figures of the capacitance value, while the third digit represents the number of zeros to add to the end of the value (in this case, 4 zeros or 0.1 µF).
