The Miflex KPAL03F412J is a capacitor constructed of aluminum-polypropylene-paper, with a capacitance of 0.12uF, a rated voltage of 250VDC, and a tolerance of ±5%. It is designed to store and release electrical energy over time, and is commonly used in power supply filtering, signal coupling, timing, and other various circuits. It provides excellent frequency, median, and dielectric strength performance due to its combination of furrow capacitor layers. Additionally, its high dielectric constant and low ESR contribute to its superior performance in most applications.
