It is a solution of simple capacitance decade. It gives a possibility of rapid selection of capacity during the construction of prototypes. The device was made of SMD capacitors, adjusters of BCD code, pieces of universal board and HEADERS.
Pictures:
Construction is simple, as shown in the pictures. Each grade consists of capacitors connected in parallel via further contacts of the code adjuster and so far for 1 grade – 1 capacitor, for 2 grade – 2, for 3 – 4 and for 4 – 8 capacitors, so 15 capacitors are needed for one grade.
Rails for connecting the further grades of the decade were made of HEADER sockets.
You can create a decade of range:
- from 1nF to 999nF
- from 10nF to 9uF
- from 100nF to 99uF
- single decade (perfect when building prototypes on universal contact boards)
