General radio 1409X standard capacitor 0.5UF refurbed
General Radio 1409X Standard Capacitor 0.5uF Refurbed
The 1409U Standard Capacitor is a fixed mica capacitor. It is a high stability unit for use in two-terminal reference or working standards in the laboratory.
These capacitor units consist of a silvered-mica and foil pile, spring-held in a heavy metal clamping structure for mechanical stability. The units are selected for low dissipation factor and are stabilized by heat cycling. Housed with silica gel to provide continuous desiccation, in cast aluminum cases, sealed with high-temperature potting wax. A well is provided in the wall of the case for the insertion of a dial-type thermometer. Three jack-top binding posts are provided on the top of the case and removable plugs on the bottom, for convenient parallel connection without error.
* Accuracy is certified within +/- 0.05% of the nominal capacitance value (two-terminal).
* Dissipation factor is less than 0.0003 at 1 kHz and 23Deg C.
