Electrolytic Bipolar Capacitor 47µF 25V THT 10×12.5mm

Electrolytic Bipolar Capacitor 47µF 25V THT 10×12.5mm is a through-hole, non-polar electrolytic component offering 47 microfarads of capacitance with a rated voltage of 25 volts. Its bipolar construction allows it to operate in AC coupling and bipolar signal applications without concern for polarity, and the THT (through-hole technology) package with 10×12.5 mm dimensions provides a reliable mechanical connection to printed circuit boards for repair, prototyping and industrial electronic assemblies.

Advantages

The bipolar electrolytic design enables safe use in circuits with reversing or alternating voltages, eliminating the need for series/parallel balancing or complex polarity arrangements. Its compact 10×12.5 mm package balances board space efficiency with mechanical stability from through-hole leads. The capacitor delivers stable capacitance suitable for audio coupling, signal path decoupling and AC filtering while simplifying assembly and replacement in hand-soldered or wave-soldered boards.

Suitable for

• AC coupling and decoupling in audio circuits
• Bipolar signal paths where non-polar behavior is required
• Prototyping and repair of consumer and industrial electronics
• Power supply AC filtering and transient suppression in low-voltage circuits

Key specifications

• Capacitance: 47 µF
• Rated voltage: 25 V
• Type: Bipolar (non-polar) electrolytic
• Mounting: Through-hole (THT)
• Package dimensions: 10 × 12.5 mm (diameter × height)
• Lead format: axial/straight leads suitable for PCB insertion

How to use

Install the capacitor in the PCB using the through-hole leads, ensuring correct mechanical seating and soldering to provide reliable electrical contact. Because the component is bipolar, orientation is not critical; either lead may be connected to signal or supply lines. Observe standard soldering temperature profiles for electrolytic components and allow sufficient cooling time after soldering. Confirm the capacitor's physical fit and clearance in the assembly, particularly in stacked or compact boards.

Usage recommendations

Use this bipolar electrolytic capacitor in circuits with alternating or reversing voltages, such as audio coupling stages and bipolar signal lines. Avoid exposing the capacitor to voltages exceeding its 25 V rating and follow PCB layout practices that minimize ripple and thermal stress. For long-term reliability, operate within the capacitor's rated temperature and voltage limits and replace aged components showing increased leakage or reduced capacitance.
