## Description

The KEMET FT0H335ZF is an Electric Double Layer Capacitor (EDLC) from the FT Series, utilizing an aqueous electrolyte construction within a radial cylindrical coin-style package. This through-hole component offers a nominal capacitance of 3.3 F with a wide tolerance of -20% to +80% and a rated DC working voltage of 5.5 VDC. Designed for robust performance in demanding thermal environments, the supercapacitor features an equivalent series resistance (ESR) of 1000 mOhms measured at 1 kHz and operates across a temperature range of -40°C to 85°C, with a verified operational lifetime of 1000 hours at the maximum rated temperature. Physical dimensions include a 36.5 mm case diameter, a maximum height of 15 mm, and a standard 15 mm lead spacing with radial pin terminals configured for secure PCB mounting.

This EDLC is engineered for energy storage and power backup applications where high capacitance density and reliable transient response are required. Typical deployment scenarios include real-time clock (RTC) hold-up power, memory backup in industrial automation systems, auxiliary power sources for smart utility meters, and load-leveling in pulse-load electronic architectures. The component's 5.5 V rating and low leakage current characteristics—specified at 5 mA after 30 minutes of charging—make it well-suited for integration downstream of voltage regulators in embedded systems requiring extended discharge cycles during primary power loss events.
