Vishay Intertechnology introduces a new series of metalized polypropylene AC filtering film capacitors optimized for high humidity environments. Vishay Roederstein MKP1847C AC Filtering devices withstand demanding temperature humidity bias (THB) testing —40C, 93 % relative humidity for 56 days at rated voltage —without altering their electrical characteristics.

Humidity may affect the life expectancy of a component by creating stresses on the part materials and altering its electrical properties in a way that the component reliability is significantly diminished. Temperature Humidity Test is those performed with the aim of evaluating the properties of materials used in components and the reliability of non-hermetic packaged devices in humid environments.

Class 2 capacitors can be divided in: those with a moderate temperature dependence (X7R or 2C1) and others that only a fraction of the capacitance remains at the temperature limits (Z5U or 2F4).

Capacitors with Class 1 ceramic are manufactured with temperature coefficients between +100 and –1500 ppm/°C. In tables and diagrams we will confine ourselves to the type that is called NP0 or COG (0 ± 30 ppm/°C)

When aircraft manufacturers started to install just two seats instead of three in airliner cockpits in the 1980s, this was something of a mini-revolution. Since that time, planes have generally been flown by just the pilot and co-pilot.
