LKG1E332MESZCK

The LKG1E332MESZCK from Nichicon is a snap-in, radial aluminum electrolytic capacitor specified at 3300 µF and 25 V. It is part of the LKG series designed for audio equipment and high-fidelity applications, offering a balance of capacitance, ripple-handling and endurance for power-supply and audio filtering functions.

This capacitor is a polarized snap-in can (φ22 × 50 mm) with tray packing and RoHS compliance. Key measured parameters include tanδ = 0.22 (20°C, 120 Hz), low-frequency ripple current 2.5 A (120 Hz), and specified leakage current of 860 µA.

Key Features

• Capacitance and Voltage — 3300 µF nominal capacitance at a rated voltage of 25 V with a tolerance of ±20% (120 Hz, 20°C).
• Audio-focused design — Part of Nichicon’s LKG series developed for audio equipment, intended to support high-fidelity audio circuitry.
• Power handling — Low-frequency ripple current rating of 2.5 A at 120 Hz to support smoothing and filtering in power supplies and audio amplifiers.
• Loss characteristics — Tangent of loss angle (tanδ) of 0.22 measured at 20°C and 120 Hz, providing a documented dissipation factor for design considerations.
• Leakage current — Specified leakage current of 860 µA, measured after voltage application conditions noted in the product data.
• Reliability and life — Endurance rating of 1000 hours at 85°C with performance criteria for capacitance, tanδ and leakage current after recovery to 20°C.
• Operating temperature range — −40°C to +85°C, suitable for a wide range of ambient conditions.
• Package and mounting — Snap-in radial can package (φ22 × 50 mm) for secure mechanical mounting in chassis or PCB assemblies; supplied in tray packing.
• Regulatory — RoHS compliant per product data.

Typical Applications

• High‑Fidelity Audio Amplifiers — Used for power-supply smoothing and decoupling where stable bulk capacitance and defined dissipation characteristics support audio performance.
• Audio Power Supplies — Provides bulk filtering and ripple control in linear and discrete audio power supply designs, leveraging the 2.5 A ripple rating at 120 Hz.
• Pre‑amplifier and Signal Conditioning — Acts as local reservoir capacitance in analog front ends where consistent capacitance and documented tanδ influence performance.

Unique Advantages

• Audio-grade pedigree: Designed as part of Nichicon’s LKG series for audio use, aligning component selection with high‑fidelity equipment requirements.
• Documented dissipation factor: tanδ specified at 0.22 (20°C, 120 Hz), enabling engineers to account for dielectric losses in thermal and frequency-domain analyses.
• Robust ripple capability: 2.5 A low-frequency ripple current rating at 120 Hz, supporting effective smoothing in audio power chains.
• Wide operating range: −40°C to +85°C operation and a 1000-hour endurance rating at 85°C provide predictable performance under extended thermal stress.
• Tray-packed snap-in format: Radial, snap-in can package (φ22 × 50 mm) for reliable mechanical retention and simplified assembly into enclosures or pcbs designed for snap-in capacitors.
• Regulatory compliance: RoHS compliant, supporting environmental and regulatory requirements.
