NON
POLAR ALUMINUM ELECTROLYTIC
NPR, NPA (Non
Polarized) SERIES
SUBMINIATURE N0N
POLARIZED
(NPR: Radial Leads, NPA: Axial Leads)
The NPR and NPA Series subminiature aluminum electrolytic
capacitors are especially designed for use in circuits whose po-
larity is reversed or unknown or in crossover networks which do
not require tough characteristic requirements.

STD 202, Method 208
Marking:
Consists of series type, nominal capacitance, rated
voltage, temperature range, anode and/or cathode
identification, vendor identification.
Recommended Cleaning Solvents:
Methanol, isopropanol ethanol, isobutanol, petroleum
ether, propanol and/or commercial detergents. Halo-
genated hydrocarbon cleaning agents such as Freon
(MF, TF, or TC), trichloroethylene, trichloroethane, or
methylchloride are not recommended as they may
damage the capacitor.
