0402ZJ100JBWTR

Thin-film capacitors are currently considered to have outstanding features such as small size, light weight, low ESR, and more importantly, their outstanding capacitance stability throughout their lifetime. The 0402ZJ100JBWTR is a great example of the technology, but to understand it better it’s important to understand its application field and working principle.

Application field

The 0402ZJ100JBWTR model is a 0402 (4.0 × 0.2mm) miniature chip capacitor manufactured based on thin-film technology. It is applicable in a wide range of applications from general use to military and aerospace applications. Its small size makes it especially suitable for use in intensive space applications or the most complex circuits, and it is especially suitable for use in high frequency circuits due to its low ESR. Furthermore, its wide operating temperature range make it extremely adaptable to harsh environments where other devices could not withstand.

Working principle

Thin film capacitors make use of a method of depositing an insulating film, usually Pb(Ti,Zr)O3 (PTZ), on both sides of a metal substrate. The thin films form a stack with conductive patterns that act as the electrodes for the capacitor. The properties of the thin-film material, combined with the size of the electrodes, determine the capacitance of the device. The high precision in film deposition results in a very uniform thickness and a nearly ideal electrical distribution, giving thin-film capacitors an advantage over other types of capacitors in terms of precision and reliability. In addition, because the thin-films are dielectric layers, they are also highly resistant to changes in temperature and environmental conditions, which makes them extremely stable over the lifetime of the device.

The 0402ZJ100JBWTR, as mentioned before, is a great example of a thin-film capacitor. It is a highly reliable and accurate device, and its small size and low ESR makes it a perfect fit for high frequency applications. Furthermore, its wide operating temperature range and superior capacitance stability make it ideal for harsh environments and long-term use.
