Capacitor 120 μF electrochemical aluminium, No name, model Czę000344

Electrolytic aluminium capacitor with a nominal capacitance of 120 μF from No name, model Czę000344. This polarised capacitor is intended for general-purpose electronic circuits that require DC filtering, decoupling and smoothing of voltage ripples. The component is suitable for power supply filtering, audio signal path decoupling and timing or control circuits where a compact aluminium electrolytic capacitor with 120 μF capacitance is needed. Verify polarity and voltage rating on the capacitor body before fitting to the circuit.

Advantages

The aluminium electrolytic construction provides a relatively high capacitance-to-volume ratio, making the 120 μF capacitor suitable for compact boards and devices. Its polarised design allows effective smoothing of DC voltage ripple and transient suppression in low- to medium-frequency power circuits. The component is broadly compatible with common electronic designs that require reliable bulk capacitance for decoupling and filtering.

Suitable for

• Power supply smoothing in linear and switch-mode supplies
• Decoupling and bulk storage for audio and control electronics
• Ripple reduction on DC rails and intermediate filter stages
• General-purpose electronic repairs and prototype builds

Key specifications

• Nominal capacitance: 120 μF
• Dielectric type: aluminium electrolytic
• Polarity: polarised (observe +/−)
• Typical applications: DC filtering, decoupling, ripple smoothing
• Package: axial or radial lead mounting depending on variant

How to use

Identify the capacitor’s polarity marking and intended voltage rating before installation. Fit the capacitor so that the positive and negative leads match the circuit’s polarity; reverse connection can damage the part and the circuit. For through-hole variants, insert leads through the PCB, solder securely and trim excess lead length. For replacement or repair work, choose a capacitor with equal or higher voltage rating and equal capacitance for safe and compatible operation.

Usage recommendations

Store and handle the capacitor in a dry environment and avoid exposure to excessive heat during soldering. When selecting a replacement, prefer the same capacitance and an equal or higher voltage rating; for improved longevity, select components rated for higher temperature or lower ripple current where the application demands it.
