Product Overview

The SAMXON GT Series Aluminum Electrolytic Capacitors are polar, foil-type capacitors designed for use in electronic equipment. Meeting IEC60384 standards, these capacitors offer reliable performance with a wide operating temperature range of -40C to 105C. They are constructed with tinned CP wire leads, aluminum wire terminals, and an aluminum case, sealed with end seal rubber and finished with a PET vinyl sleeve. The GT series is suitable for various electronic applications requiring stable capacitance and low leakage current.
