Thin Film Capacitors

The 0402J1R3PBSTR application field and working principle are relevant to thin film capacitors. Thin film capacitors function by having an active layer of an insulator material (typically with a dielectric constant between 4 and 8) sandwiched between two conductive electrodes. It has very low of ESR and ESL and a very high frequency characteristics. High-k dielectric is an ideal product for low loss, high reliability and wide range of temperature to have the same electrical characteristics.
Thin film capacitors are widely used in several industries such as medical, automotive, aerospace and industrial sectors. This is due to its capability of operating in a wide variety of temperatures, from -55°C to 125°C, providing reliable and stable performance of the system. 0402J1R3PBSTR is an example of such a capacitor and is used in applications requiring high performance, such as in automotive and high-end consumer audio products. Its low profile size (1.4mm)and low inductance (<50nH) allows for its use in space-restricted designs.
In addition, 0402J1R3PBSTR is also known for its high frequency response, enabling it to be used in high-speed signal and power applications. Its miniature package and low profile size allow it to be used in space-restricted and high-density circuit designs. Furthermore, it has a wide operating temperature range, ranging from -55°C to 125°C, enabling its use in applications such as automotive or aerospace electronics where extreme environmental conditions exist.
The working principle of 0402J1R3PBSTR is the same as other types of thin film capacitors. In this type of capacitor the active layer is made of an insulator material usually with a dielectric constant between 4 and 8 and two conductive electrodes. The two electrodes are separated by a dielectric material which is generally made from a variety of polymers.The working principle is such that when a voltage is applied between the two electrodes, electrons are attracted and moved to the negative electrode. This movement of electrons creates an electric field between the two electrodes which is called capacitance. The capacitance forms a parallel plate capacitor in which the distance between the two plates is much smaller than the size of the plates. This means that as the distance between the plates is decreased, the capacitance increases.
The 0402J1R3PBSTR, with its high frequency response, low profile size and wide operating temperature range, is the perfect candidate for a number of applications looking for relaible and stable performance. It can be used in automotive and aerospace electronics and in high-end consumer audio products because of its miniature package and low inductance. It also has a wide operating temperature range which enables it to be used in applications where extreme environmental conditions exist.
