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 po­larity is reversed or unknown or in crossover networks which do
not require tough characteristic requirements.

MECHANICAL SPECIFICATIONS

Lead Solderability:

Meets the requirements of MIL−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. Halo­genated hydrocarbon cleaning agents such as Freon
(MF, TF, or TC), trichloroethylene, trichloroethane, or
methylchloride are not recommended as they may
damage the capacitor.
