I'm having trouble deciphering some abbreviations in a parts list of capacitors from a technical manual for an old (80s-90s) computer. I've managed to work out that "CPCTR" stands for "Capacitor", however I'm not sure about the abbreviations after that. I guess they describe the type of capacitor? Here's the different types listed:

  • CPCTR CPLT
  • CPCTR CER ("Ceramic" maybe?)
  • CPCTR TANT
  • CPCTR DCPLR ("DC Polarized" maybe?)
  • CPCTR ALEC

The one I really need to translate is CPCTR DCPLR. The others are provided mainly for context. Google has been no help I'm afraid.

    \$\begingroup\$ Typical values (and voltage ratings) could be a good clue. \$\endgroup\$ – Spehro Pefhany Jan 28 at 9:16

Quite likely: DECOUPLER

Source

Remove the decoupling capacitor 'A' nearest to 1C1

Part list: Item Part No. Description Qty Remarks
92   0680,100 CPCTR DCPLR 33/47n AX 12V 39 'A'

From other part lists, it is said to be a SMD component.
