Film capacitors, also known as plastic film capacitors, are a type of capacitor, often used in signal and filter circuitry, that uses a plastic film as its dielectric material. The B25856J8105K3 is a film capacitor from Murata, designed for applications that require high capacitance in a small area for small- and medium-sized surface-mount devices. It is a safety-certified part, meeting ENEC requirements.

The B25856J8105K3 film capacitor is available in two package sizes: 1206 and 1806. The 1206 package measures 3.2mm x 1.6mm, while the 1806 package measures 3.7mm x 2.1mm. These small sizes make the B25856J8105K3 well-suited for applications that require high capacitance with limited physical space, such as portable electronics and medical devices.

The B25856J8105K3 is available in an X5R dielectric material, with a voltage rating of 16V and a temperature range of -55°C to +85°C. It has a capacitance range of 0.15uF to 1.0uF. With its low ESR and ESL, the B25856J8105K3 is ideal for high-frequency applications. Its 93% energy saving rating makes it an environmentally friendly option.

In terms of applications, the B25856J8105K3 is suitable for use in a variety of electronic circuits, such as motor control inverters, mobile phones, audio amplifiers, and LED lighting. Its small size also makes it ideal for use in portable devices, such as PDAs, digital cameras, and cellular phones. Additionally, due to its safety-certification, the B25856J8105K3 is also suitable for use in medical and industrial applications.

The working principle of the B25856J8105K3 is simple. It is a polarized device, so the voltage must be applied in the correct polarity in order for the capacitor to work. When an AC voltage is applied to a B25856J8105K3, the electric field created by the voltage causes the film to charge and store the electrical energy, which is then stored in the capacitor until the voltage is removed. This stored energy allows the capacitor to draw current from the AC source while still maintaining the same voltage level.

In summary, the B25856J8105K3 is a high-performance film capacitor from Murata, designed for applications that require high capacitance in a small area. It has a voltage rating of 16V and a temperature range of -55°C to +85°C, and is available in two package sizes: 1206 and 1806. With its low ESR and ESL, the B25856J8105K3 is suitable for use in high-frequency applications, and its 93% energy saving rating makes it an environmentally friendly option.
