The {{Title|General Radio 980-G Decade Capacitor Unit}} was introduced in {{Catalog P}} and remained available through {{Catalog S}}. 

The Type 980-G is a decade capacitance unit that contains four Type [[505]] silver mica standard capacitors. The capacitor values are selected in a "1-2-2-5" combination. In the Type 980-F these values are 0.01, 0.02, 0.02, and 0.05 μF.  The eleven position [[980-P1]]
switch maintains a combination of the four standard capacitors in parallel to produce the decade of capacitance values. The Type 980-F decade unit is a component of the Type [[1419-K]] Decade Capacitor.
