Electrolytic Capacitor THT 4700µF 35VDC Ø18×35.5mm

Axial through-hole electrolytic capacitor with 4700µF capacitance and a rated voltage of 35VDC. The capacitor has a cylindrical aluminum case with a diameter of 18 mm and a length of 35.5 mm, providing a compact solution for high-capacitance requirements. It is intended for smoothing, filtering and energy storage in power supplies, audio amplifiers and other electronic circuits where bulk decoupling and stable voltage performance are needed.

Advantages

This electrolytic capacitor offers high capacitance in a relatively small axial THT package, allowing effective bulk decoupling and reduced ripple in DC rails. The 35V rated voltage makes it suitable for medium-voltage circuits while the axial leads facilitate straightforward through-hole mounting and reliable mechanical retention on PCBs. The cylindrical Ø18×35.5mm body balances capacity and board space, making it suitable where radial sizes would be too large or lead orientation must be inline.

Suitable for

• Smoothing and filtering in switch-mode and linear power supplies
• Bulk decoupling on power rails for amplifiers and audio equipment
• Energy storage and transient suppression in industrial electronics
• Power supply rails in consumer electronics and DIY projects

Key specifications

• Capacitance: 4700 µF
• Rated voltage: 35 V DC
• Package type: axial through-hole (THT)
• Case dimensions: diameter 18 mm, length 35.5 mm
• Polarization: polarized electrolytic capacitor
• Primary use: smoothing, filtering, bulk energy storage

How to use

Mount the capacitor in the correct polarity: the negative lead must be connected to the lower potential or ground. Insert the axial leads through the PCB holes and solder using appropriate soldering temperature and technique to avoid overheating the component. Observe sufficient lead spacing and secure mechanical support if the assembly will be subject to vibration. Ensure the working voltage in the circuit does not exceed 35V DC and allow for appropriate voltage margin according to application requirements.

Usage recommendations

For long-term reliability, avoid exposing the capacitor to temperatures above its rated operating range and minimize ripple current beyond the component’s specification. When replacing existing capacitors, match capacitance and voltage, and check polarity carefully. Allow adequate ventilation in power supply enclosures and consider paralleled capacitors for lower effective series resistance or higher ripple current handling when required.
