Electrolytic Capacitor THT 100µF 25V Ø5×11 mm radial leaded

Radial leaded THT electrolytic capacitor with 100µF capacitance and a 25V DC rated voltage in a compact cylindrical package (Ø5×11 mm). Designed for through-hole PCB mounting, this electrolytic capacitor provides bulk energy storage and voltage smoothing in power supply filtering, decoupling and timing circuits. Its small diameter and short body length make it suitable for space-constrained boards while delivering the characteristics expected from aluminum electrolytic capacitors used in general-purpose electronic assemblies.

Advantages

This THT electrolytic capacitor combines a relatively high capacitance with a moderate voltage rating in a compact radial-leaded package, enabling reliable smoothing of DC rails and energy buffering in small form-factor designs. The component offers stable performance within its rated temperature and voltage limits and is compatible with standard through-hole soldering processes. Its cylindrical Ø5×11 mm dimensions make it straightforward to place in dense PCB layouts without requiring special holders or mounting hardware.

Suitable for

• Power supply filtering on single-sided and double-sided through-hole PCBs
• Decoupling of analog and digital circuits to reduce noise and ripple
• Timing and coupling circuits where bulk capacitance is required
• Repair and prototyping of consumer electronics, industrial controllers, and hobby projects

How to use

Select the capacitor polarity correctly before insertion: the negative terminal is typically marked on the can. Insert the radial leads into the appropriate through-holes on the PCB so that the polarity aligns with the circuit schematic. Solder using standard through-hole soldering techniques, observing recommended soldering temperatures and durations for electrolytic capacitors to avoid overheating the component. After soldering, trim excess lead length and inspect solder joints for good wetting and mechanical stability. Ensure the operating voltage in the circuit does not exceed the 25 V rating and that expected ripple currents and ambient temperature remain within the component's specified limits.

Usage recommendations

For long-term reliability, derate the component by choosing operating voltages significantly below the 25 V rating when possible, and allow for adequate spacing from heat-generating components. If the application involves high ripple currents or elevated ambient temperatures, select a capacitor with higher ripple current rating or larger case size. Store and handle the capacitor in dry conditions and avoid prolonged exposure to temperatures outside the manufacturer’s recommended storage range.
