4.7uF 250V Electrolytic Capacitor SAMWHA 4.7uF 250V

Product Overview

The 4.7uF 250V SAMWHA Electrolytic Capacitor ETA2231 is a high-voltage, polarized radial aluminum through-hole component. Developed by Samwha Electric, a well-regarded name in passive electronics, this miniature capacitor is designed for applications requiring low capacitance coupled with a strong voltage tolerance.

Belonging primarily to Samwha’s reliable general-purpose SD Series, it excels at DC voltage smoothing, analog signal decoupling, and small input filtering. Its 250V rating makes it heavily favored for the startup and filtering sub-circuits of Switched-Mode Power Supplies (SMPS), small LED drivers, and industrial timing circuits.
