The LKG2A332MESCBK is a Nichicon LKG series snap-in aluminum electrolytic capacitor specified at 3.3 mF (3300 µF) and 100 V with ±20% tolerance. Engineered for audio equipment, the LKG family emphasizes high-tone quality and reliability for high-grade and HD audio applications.

Key electrical and mechanical attributes include snap-in mounting (radial can), a case diameter of φ35 × 50 mm, polarized construction, RoHS compliance, and a rated operating temperature range of -40 °C to +85 °C. Note: this specific part is listed as End of Life / Discontinued.

Key Features

• Capacitance and Voltage — 3.3 mF (3300 µF) rated at 100 V with a capacitance tolerance of ±20% (measured at 120 Hz, 20 °C).
• Audio-focused design — Part of the LKG series designed for high-grade and HD audio equipment, intended to prioritize tone quality in audio signal and power stages.
• Low-frequency loss characteristic — Specified tangent of loss angle (tan δ) of 0.57 (measurement frequency: 120 Hz at 20 °C), supporting predictable loss behavior for designs that track dissipation.
• Ripple handling — Rated ripple current of 4.95 A at 120 Hz, suitable for smoothing and filtering tasks in audio power supplies.
• Temperature and endurance — Operating temperature range from -40 °C to +85 °C with endurance defined as 1000 hours at 85 °C under rated voltage; capacitance change remains within ±20% after endurance testing.
• Leakage current specification — Leakage is specified as not more than 3√(C·V) µA after 5 minutes at 20 °C (C in µF, V in volts), enabling predictable bias current for circuit design.
• Mounting and package — Snap-in radial can package for secure chassis/board retention; physical size approximates φ35 × 50 mm (L: 5 × D: 3.5 cm).
• RoHS compliant — Meets RoHS directive requirements referenced in the datasheet.

Typical Applications

• High‑grade audio amplifiers — Bulk smoothing and decoupling in amplifier power supplies where audio tone quality is a priority.
• HD audio equipment — Energy storage and power stabilization in high-fidelity playback or preamplifier circuits.
• Audio power filters — Use in filter networks and supply rails to manage ripple current and provide stable DC for sensitive analog stages.

Unique Advantages

• Audio-oriented tuning: The LKG series is explicitly designed for high‑tone quality in audio equipment, making this capacitor suitable for projects where sonic characteristics matter.
• High voltage and substantial capacitance: 100 V rating combined with 3.3 mF capacitance supports high‑headroom power rails and bulk energy storage in audio power supplies.
• Predictable endurance: Specified 1000 hours at 85 °C under rated voltage with defined limits for capacitance change, tan δ, and leakage current for long-term design planning.
• Clear electrical specs for design: Defined ripple current (4.95 A @ 120 Hz), leakage current formula, and tan δ value enable accurate thermal and performance calculations.
• Robust low‑temperature behavior: Datasheet impedance ratios (Z at -25 °C and -40 °C relative to +20 °C) provide guidance on performance in cold environments.
• Secure mounting: Snap-in radial can package simplifies mechanical retention and installation in chassis-mounted and board-mounted power sections.
