a substance that is a poor conductor of electricity, but an efficient supporter of electrostatic field s.
The DC Voltage ratings are the AC voltage values times 1.41 (usually rounded).
In general the AC voltage assumes a 50-60 Hz sinusoidal waveform and is the RMS (root mean squared) value.
The operating temperature is the range of ambient temperature within which a power supply, or any other electrical equipment, operate in. This ranges from a minimum operating temperature, to a peak or maximum operating temperature, outside which, the power supply may fail.
Semiconductor package is a carrier / shell used to contain and cover one or more semiconductor components or integrated circuits. The material of the shell can be metal, plastic, glass or ceramic.
Parts can have many statuses as they progress through the configuration, analysis, review, and approval stages.
the variation of output frequency of a crystal oscillator due to external conditions like temperature variation, voltage variation, output load variation, and frequency aging.
a count of all of the component leads (or pins)
the distance between two baselines of lines of type. The word 'leading' originates from the strips of lead hand-typesetters used to use to space out lines of text evenly. The word leading has stuck, but essentially it's a typographer's term for line spacing.
the amount of capacitance measured or computed across the crystal terminals on the PCB. Frequency Tolerance. Frequency tolerance refers to the allowable deviation from nominal, in parts per million (PPM), at a specific temperature, usually +25°C.
the maximum allowable deviation from the nominal crystal frequency at a specified temperature, usually 25℃. The recommended frequency tolerance of the crystal over the manufacturing process is ±50 ppm.
