Pack of 20 radial electrolytic capacitors — 1000uF, 25V, 105°C, 10 x 17 mm, black case What this does Provides bulk energy storage to support DC power rails. Smooths voltage and reduces ripple on supply lines. Stabilizes power for regulators, converters, and audio circuits. Key benefits — why you need these High capacitance in a compact 10 x 17 mm package gives strong smoothing without taking much board space. 25V rating covers common supply rails (for example 5V, 12V and other mid-range voltages with margin). 105°C temperature rating ensures reliable operation under elevated temperatures and heavier loads. Radial through-hole leads simplify PCB assembly and mechanical mounting for robust installations. Black case with standard footprint fits typical through-hole layouts and replacement needs. Features & specifications Quantity: 20 pieces Capacitance: 1000uF each Voltage rating: 25V DC Temperature rating: 105°C Dimensions: 10 x 17 mm Lead style: radial, through-hole Case color: black Function: bulk energy storage, smoothing, ripple reduction Compatibility and common applications Ideal for through-hole PCBs used in power supplies, DC-DC converters, linear regulators, audio electronics, and LED drivers. Works well where higher capacitance and elevated temperature tolerance are required. Practical use scenarios 1) Microcontroller projects — smoothing and decoupling on 5V or 12V supply rails to reduce voltage dips when peripherals switch on. 2) Power conversion — input/output filtering for DC-DC converters and linear regulators to lower ripple and improve stability. 3) Audio equipment — power rail stabilization and ripple reduction in amplifiers and preamps to minimize hum and noise. Why choose this pack Ready-to-use set of 20 identical capacitors simplifies procurement and assembly for prototypes or production runs. Suitable for common supply voltages, durable under higher operating temperatures, and easy to mount on through-hole PCBs.
