LKG1J223MKZ

The LKG1J223MKZ is a lug‑terminal (lag terminal) aluminum electrolytic capacitor from Nichicon's LKG series, purpose‑built for audio equipment. It delivers large bulk capacitance and rated voltage for smoothing and energy storage in high‑fidelity audio power supplies and amplifier systems.

Engineered with audio performance in mind, the LKG series emphasizes sound quality while providing practical electrical characteristics—high capacitance, substantial low‑frequency ripple handling, and endurance for sustained operation up to 85°C.

Key Features

• Capacitance & Rated Voltage — 22,000 µF nominal capacitance with tolerance of −20% to +20% at a rated voltage of 63 V.
• Low‑Frequency Ripple Current — 9.1 A ripple current rating at 120 Hz for robust handling of power supply ripple in audio systems.
• Dissipation Factor (tan δ) — tanδ = 0.3 measured at 20°C, 120 Hz, providing a quantified loss characteristic for design tradeoffs.
• Leakage Current — Specified leakage of 3530 µA after application of rated voltage (per product data).
• Endurance — Rated for 1000 hours at 85°C (endurance condition per series specification) with defined limits on capacitance change, tanδ and leakage after recovery to 20°C.
• Operating Temperature Range — −40°C to +85°C to support a wide range of audio equipment environments.
• Mounting & Package — Lug (solder‑lug) terminal, radial can package; supplied in tray packing for handling and assembly.
• Physical Size — Case dimensions φ50 × 100L (L: 10 × D: 5 cm) for designs requiring substantial capacitor volume.
• Audio‑Focused Series Design — Part of the LKG line designed for high‑grade audio equipment, prioritizing high‑fidelity sound quality.
• RoHS Compliant — Conforms to RoHS requirements as indicated in series documentation.

Typical Applications

• Professional audio power supplies — Bulk reservoir and smoothing capacitor for amplifier and preamplifier power rails, helping stabilize supply under dynamic loads.
• High‑fidelity amplifiers — Provides high capacitance and ripple handling to support low‑noise, high‑current audio stages.
• Studio and broadcast equipment — Energy storage and filtering in rack‑mount and fixed installations where sustained performance is required.

Unique Advantages

• Large energy reservoir: 22,000 µF at 63 V supplies substantial stored energy for smoothing and transient demands in audio power systems.
• High low‑frequency ripple capability: 9.1 A at 120 Hz reduces voltage modulation from rectified mains and dynamic amplifier loads.
• Audio‑centric engineering: The LKG series is explicitly designed for high‑grade audio equipment with an emphasis on fidelity.
• Proven endurance: 1000 hours at 85°C endurance rating ensures predictable performance over prolonged elevated temperature use.
• Robust mechanical mounting: Lug (solder‑lug) terminal and radial can construction facilitate secure high‑current connections in chassis or PCB installations.
• Wide operating temperature: −40°C to +85°C supports deployment across typical audio equipment environments.
