Thin Film Capacitors are widely used in a variety of electronic applications, such as telecommunications, military equipment and medical devices. The 08055J140FBTTR is one such capacitor, developed and manufactured by Motorola, that is used for various applications. This article will discuss the application field and working principle of the 08055J140FBTTR.

The 08055J140FBTTR is a Type 2 capacitance-adjustable Thin Film Capacitor with a range of 5 to 1400pF. It features an adjustable capacitance in the NC8-BPW package that is 9.2mm long and 3.2mm thick. This capacitor offers the opportunity to precisely adjust the capacitance values by simply moving the rotor. It has an excellent low-loss coefficient and low parasitic residual capacitance. In addition, the double-ended construction ensures high-quality performance and low output electric field.

One of the main application fields for the 08055J140FBTTR is telecommunications. This capacitor is used for numerous tasks in modernizing telecommunications networks, such as adjusting the maximum allowed frequency of operation or providing equalization across signal paths. It is also used in transceiver networks to achieve gain adjustment. Other applications include networking systems, frequency correction, cable television and signal routing.

The working principle of the 08055J140FBTTR involves the capability of adjusting the capacitance by simply moving the rotor. Its construction includes a permanent magnet and a rotor that are configured to interact with each other. As the magnet rotates, the rotor adjusts the capacitance values depending on the number of turns it makes. This adjustment is independent of any external factors and is therefore very precise. The Thin Film Capacitor can provide output capacitance values that are exact, as the rotor is designed to return to its initial position when turned.

The 08055J140FBTTR Thin Film Capacitor is also designed with a varistor to protect against overvoltage, overcurrent and ESD. It can be used for RF, broadband and communication applications with different operating voltages. Additionally, it operates in temperatures ranging from - 55oC to 185oC and offers a high reliability of MIL-STD-810F.

In conclusion, the 08055J140FBTTR Thin Film Capacitor is a Type 2 capacitance-adjustable capacitor that is widely used in telecommunications, particularly for adjusting the maximum allowed frequency of operation, equalization across signal paths and gain adjustment. The working principle of the capacitor requires a permanent magnet, rotor and varistor to adjust the capacitance values. It features an adjustable capacitance that is independent of any external factors and has a wide operating temperature range.
