R75UI11004040J

Film Capacitors are among the most widely used components in electronic circuits. In addition to storing electrical energy, they provide excellent AC impedance, easy layout and mounting in a variety of products, and low acoustic noise. The R75UI11004040J is a renowned film capacitor that boasts a wide application field and a straightforward working principle.

First released in 1981, the R75UI11004040J is a type of an ultra thin Polyethylene Naphthalate (PEN) film capacitor. This well-known brand of PEN capacitors can handle a ripple current up to 3.5A and also provide excellent durability withstanding up to seven thousand hours of continuous operation. The value of the capacitance of the R75UI11004040J is 10μF and it has an approximate size of 10 * 15 * 12mm (L * W * H). PEN film capacitors are superbly suitable for various audio applications such as ornaments and amplifiers,especially for portable electronics. They are designed for low current, high frequency applications and come with a very wide operating temperature range from -55 °C to 125 °C.

The R75UI11004040J operates on the same principle as other capacitors: when a voltage is connected to two plates, current flows through until it reaches equilibrium. The current and voltage values depend on the capacitance and the frequency of the oscillating voltage. The electric potential between the plates of a capacitor is the product of the electric charge stored divided by the capacitance. At frequencies of 3.2 KHz or less, the electric potential decays very slowly and has reaching a value of 0.5% of the initial potential. This property enables the R75UI11004040J to handle high frequencies without distortion.

The R75UI11004040J also has an over-pressure release mechanism that keeps the plates from being pressed too hard against one another. This helps to ensure that the capacitor remains in good condition. In addition, the R75UI11004040J is designed with a special dielectric insulation layer between the plates that boosts its strength. This dielectric layer also minimizes the Dielectric absorption coefficient, resulting in better frequency response and exceptionally low distortion.

The R75UI11004040J is also unique in that its ultra-thin construction also helps reduce the amount of electricity that can be stored within the capacitor. This can be especially useful in situations where a large amount of electricity needs to be stored within a small space. Additionally, the ultra thin construction reduces the weight and size of the capacitor. This can be beneficial in situations where size and weight of components need to be minimized, such as in the design of laptops and other portable electronics.

In sum, the R75UI11004040J is an ultra thin Polyethylene Naphthalate (PEN) film capacitor that offers high performance at high frequencies as well as excellent durability. It is suitable for various audio applications including decorations and amplifiers and is designed for higher frequency, low current applications. Furthermore, its over-pressure release mechanism helps protect the capacitor from damage, while its thin construction saves on both size and weight. All in all, the R75UI11004040J is a great choice for a wide range of electronic projects.
