LKG1J332MESABK

The Nichicon LKG1J332MESABK is an aluminum electrolytic, snap‑in terminal capacitor engineered for audio equipment. It provides 3300 µF capacitance at a 63 V rating with polarized construction and a low loss tangent (tan δ ≈ 0.3), suited for power filtering and energy storage in audio systems.

Packaged in a radial can with snap‑in mounting, this component targets high‑fidelity audio applications where large capacitance, robust ripple handling, and chassis‑mount assembly are required. It is RoHS compliant and specified for operation from −40 °C to +85 °C with a rated endurance of 1000 hours at 85 °C.

Key Features

• Capacitance & Tolerance — 3.3 mF (3300 µF) with ±20% tolerance at 120 Hz, 20 °C for stable bulk energy storage and smoothing in audio power stages.
• Voltage Rating — 63 V rated voltage to support higher‑voltage audio amplifier power supplies and rail decoupling.
• Low Loss Tangent (tan δ) — Specified tan δ ≈ 0.3, indicating controlled dissipation suitable for audio signal integrity and low audible noise contribution.
• Snap‑In Radial Can Package — Snap‑in terminal mounting for secure chassis or PCB panel assembly with a compact 25 mm × 50 mm can footprint.
• Temperature & Endurance — Operating range −40 °C to +85 °C; endurance rating of 1000 hours at 85 °C for predictable life under high‑temperature operating conditions.
• Ripple Current — Rated ripple current of 3.2 A at 120 Hz, enabling handling of power supply ripple in amplifier stages.
• Leakage Current Specification — Leakage current defined as not more than 3√(C·V) (µA) after 5 minutes at 20 °C, providing a measurable guideline for standby and bias performance.
• RoHS Compliant — Conforms to applicable RoHS restrictions for lead‑free assembly environments.

Typical Applications

• Audio Power Supplies — Bulk filtering and smoothing in high‑fidelity amplifier power supplies where large capacitance and 63 V rating are required.
• Preamp and Amplifier Stages — Energy storage and decoupling to support stable biasing and transient current demands in audio front‑end circuitry.
• Chassis‑Mounted Systems — Snap‑in package simplifies mechanical mounting for rack or chassis assemblies used in professional audio equipment.
