Many microwave applications, such as repeaters, and electronic warfare equipment, require increased spectral resolution. This means these devices only need to look at a narrow slice of a given band.
While the supercapacitor developed by the team has a comparable energy density to state-of-the-art value of lead-acid batteries, its power density is two orders of magnitude higher at over 10,000 Watt per litre.
Optical fibers are delicate elements that can break easily, and their repair is not as simple as an electric wire. The optical fibers suffer great stress in the outdoor installations due to weather conditions and the installation itself.
Failures in plated through vias (PTV) can be related to different causes, some of them discussed elsewhere. Amongst them, thermomechanical fatigue is the most frequent failure mechanism observed in plated through systems. Hence, the present post analyses the typical thermally induced failures in PTV architectures.
Noise manifests itself as a spontaneously fluctuating voltage whose instantaneous amplitude is randomly distributed. The instantaneous value is both unpredictable and of minor interest except in certain critical applications. Instead, one measures a time-averaged value. It consists of the root of the mean-square value of voltage transmitted in a particular frequency pass band.
The capacitance of certain capacitors depends not only on the chosen dielectric material, geometry and temperature but also on the DC and AC bias applied to the part
As the name indicates wire-wound resistors consist of a resistive wire wound on a bobbin and supplied with a protective coating. Since the resistance wire never can serve as a termination wire because of solderability requirements, it has to be connected to the terminal leads or the like, usually by welding or brazing.
The higher the resistance value the thinner the wire that has to be used and thus the greater the risk of open circuits due to deficient weldings, damage from corrosion or from mechanical handling. Below a diameter, Φ, of 0.1 mm (4 mils) the failure rate grows rapidly.
Alter Technology is helping to shorten the cost and schedule of space programmes, providing to the final customer fast test-design records, real-time progress status, and result feedback.
Some background information about BMTI will be introduced. 1. Using built-in self-test (BIST) structures for SEE test BIST structures, scan chains and memory-BIST, are used in SEE hardness assurance of BMTI’s IC products. The basic principle, consideration and skills will be given. Some implications for SEE assurance will be discussed.
