Designed as an inexpensive answer to the problem of flux removal by solvents, these capacitors have a coating which will resist the normal post soldering cleaning process. In laboratory and user tests, including MIL202 Method 215, the coating showed a satisfactory improvement in solvent resistance and enables commercial polystyrene capacitors to be specified where flux removal techniques have previously preluded their use.
Windings are selected from the standard ‘HS’ range and the coating adds about 1mm to the length and about 0.5mm to the diameter.
