Frequently Asked Questions
What are the key electrical specifications of the SK101M250ST aluminum electrolytic capacitor?
The SK101M250ST provides 100 µF capacitance rated at 250 V with an ESR of 1990 mΩ and maximum leakage current of 0.75 mA. Its 16 mm diameter radial body uses aluminum wet electrolytic dielectric construction. These parameters make it suitable for bulk energy storage in industrial power supplies and motor drive filter stages operating up to 250 V.
In which power supply topologies does the SK101M250ST perform best as a filter capacitor?
The SK101M250ST with its 100 µF at 250 V rating is well-suited for output filter stages in flyback converters, boost PFC circuits, and linear power supplies operating from rectified mains. The 1990 mΩ ESR limits its suitability for high-frequency switching designs above 100 kHz, making it most effective in mains-frequency ripple filtering and holdup energy storage where its 250 V rating provides necessary safety margin.
How does the SK101M250ST 16 mm diameter compare to smaller radial capacitor alternatives at the same 100 µF rating?
At 100 µF and 250 V, the SK101M250ST uses a 16 mm diameter radial package which is a common size for this voltage and capacitance combination. Smaller alternatives at 105°C ratings may offer reduced diameter down to 12.5 mm but typically at higher ESR or lower voltage margins. The 16 mm body provides adequate lead spacing for standard 5 mm or 7.5 mm pitch PCB footprints used in industrial power boards.
