Reliability and Payload Budget Are Driving Factors in System Design in Space Electronics

In space electronics, reliability and payload budget are driving factors in system design. Mission-critical applications require dependable components with a proven electrical and mechanical track record in harsh environments. However, as system complexity increases, so does the need for mass and volumetric efficiency.

Class II dielectricThe insulating material between the plates of the capacitor. The material is chosen for its ability to permit electrostatic attraction and repulsion to take place across it. The material will have the property that energy required to establish an electric field is recoverable in whole or in part, as electric energy. In other words, a good dielectric material is a poor conductor of electricity while being an effective supporter of electrostatic fields. multilayer ceramic chipThe main differences between ceramic dielectricThe insulating material between the plates of the capacitor.

In other words, a good dielectric material is a poor conductor of electricity while being an effective supporter of electrostatic fields. loss.Ceramic capacitors tend to have low inductance because of their small size. capacitors (MLCCs) are employed more extensively than any other type of capacitor, accounting for trillions of components annually, exhibiting higher dielectricThe insulating material between the plates of the capacitor.

The material is chosen for its ability to permit electrostatic attraction and repulsion to take place across it. The material will have the property that energy required to establish an electric field is recoverable in whole or in part, as electric energy. In other words, a good dielectric material is a poor conductor of electricity while being an effective supporter of electrostatic fields. which determines the electrostatic energy stored per unit volume for unit potential gradient. and greater volumetric efficiency than Class I dielectrics. This advantage comes at the expense of greater capacitanceThat property of a system of conductors and dielectrics which permits the storage of electricity when potential difference exists between the conductors. Its value is expressed as the ratio of a quantity of electricity to a potential difference. A capacitance value is always positive. variation with temperature and applied voltage; however, they remain the workhorse for most decouplingA decoupling capacitor is a capacitor used to decouple one part of an electrical network (circuit) from another. Noise caused by other circuit elements is shunted through the capacitor, reducing the effect they have on the rest of the circuit, filtering, and bypass applications.

Traditionally, Class I and Class II ceramics shared similar manufacturing processes – building up successive layers of ceramic dielectricThe insulating material between the plates of the capacitor.

Advances in the ceramic material sets used to manufacture MLCCMultiple-layer capacitors interleave dielectric and electrode layers. This type of capacitor has increased current handling capacity, higher Q, and lower internal series resistance than conventional capacitors of the same size and capacitance. technology are changing that. Smaller particle size barium titanate (BT) ceramics and the development of equipment capable of creating, and subsequently firing, extremely thin ceramic layers, have enabled the production of higher reliability, higher capacitanceThat property of a system of conductors and dielectrics which permits the storage of electricity when potential difference exists between the conductors.

This process evolution enabled the production of lower voltage ratings with higher associated capacitanceThat property of a system of conductors and dielectrics which permits the storage of electricity when potential difference exists between the conductors. Its value is expressed as the ratio of a quantity of electricity to a potential difference. A capacitance value is always positive., which also aids emerging low-voltage power chipset technologies. BME technology enables a significant reduction in component size when compared to PME capacitors as typical ratios are on the order of four to eight times smaller (Figure 1). Consequently, BME technology gradually replaced PME capacitor systems in many applications, including commercial, industrial, and automotive electronics. Employed for more than 20 years now, BME capacitors currently account for approximately 99% of worldwide Class II ceramic usage and can be designed to meet the same testtest is test standards required for space electronics that have long been met by their PME forerunners.
