The {{Title|General Radio General Radio 1409-K Standard Capacitor}} was introduced in {{Catalog O}} and remained available through {{Catalog U}}. 

The 1409-K is a fixed mica capacitor of very high stability for use as two or three-terminal capacitance standards in the laboratory. The capacitor is installed in an aluminum case along with Silica gel desiccant then sealed with hi-temp potting wax. A well located on the right side 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. Each capacitor is supplied with a certificate of calibration giving two and three terminal measured capacitance. The Type 1409-K capacitor is mounted in the small case.
