Standard

Coupling Factor

Coupling Factor (CF) measures the coupling between classes excluding coupling due to inheritance. It is the ratio between the number of actually coupled pairs of classes in a scope (e.g., package) and the possible number of coupled pairs of classes. CF is primarily applicable to object-oriented systems.

19.2dB

Radiation Hardening

Radiation hardening is the process of making electronic components and circuits resistant to damage or malfunction caused by high levels of ionizing radiation, especially for environments in outer space (especially beyond the low Earth orbit), around nuclear reactors and particle accelerators, or during nuclear accidents or nuclear warfare.

No

RoHS Status

RoHS means “Restriction of Certain Hazardous Substances” in the “Hazardous Substances Directive” in electrical and electronic equipment.
