LKG2A223MKZF

The LKG2A223MKZF is a lug-terminal aluminum electrolytic capacitor from Nichicon’s LKG series, engineered for audio equipment applications. It provides 22,000 µF of bulk capacitance at a 100 V rating in a radial can with solder lug mounting for secure, high-current connections.

Key performance characteristics include a 9.7 A low-frequency ripple current rating (120 Hz), a specified tanδ of 0.25 (20°C, 120 Hz), an operating temperature range of −40°C to +85°C, and a rated endurance of 1000 hours at 85°C. RoHS compliant. Note: this part is currently listed as End Of Life.

Key Features

• Bulk Capacitance and Tolerance — 22,000 µF (22 mF) nominal capacitance with ±20% tolerance measured at 120 Hz, 20°C, suitable for large energy-reservoir and smoothing functions.
• Rated Voltage — 100 V DC rating for higher-voltage power rails and supply filtering.
• Low-Frequency Ripple Handling — 9.7 A ripple current rating at 120 Hz to support heavy AC ripple in power-supply applications.
• Leakage and Dissipation — Specified leakage current of 4440 µA and tangent of loss angle (tanδ) of 0.25 at 20°C, 120 Hz, enabling predictable dissipation and sizing for thermal management.
• Package and Mounting — Lug (solder lug) terminal, radial can configuration for secure mechanical and electrical connections in chassis-mounted or bench power designs; physical size φ63 × 80 mm length.
• Endurance and Temperature Range — Rated lifetime of 1000 hours at 85°C with an operating range from −40°C to +85°C for stability across typical audio equipment environments.
• Audio-Focused Design — Part of the LKG series specified “For Audio Use” and developed for high-grade audio equipment where bulk energy storage and stable filtering are required.
• RoHS Compliant — Conforms to RoHS requirements for restricted substances.

Typical Applications

• High-fidelity audio amplifiers — Bulk reservoir and smoothing on power rails to support stable supply for audio stages.
• Professional audio power supplies — Filtering and ripple absorption where elevated voltage and high bulk capacitance are required.
• Mixing consoles and preamplifiers — Energy storage for stable supply rails in equipment that prioritizes audio fidelity.
• Power reservoirs for discrete amplifier stages — Provides large capacitance and high ripple handling for class-A/B and other linear amplifier topologies.

Unique Advantages

• High bulk capacitance at 100 V: 22,000 µF provides substantial energy storage for smoothing and transient support on higher-voltage audio supplies.
• Strong ripple-current capability: 9.7 A rating at 120 Hz enables handling of heavy AC ripple without immediate degradation, easing thermal design.
• Audio-centric series design: LKG series is specified for use in high-grade audio equipment, aligning product construction and characteristics with audio applications.
• Secure lug-terminal mounting: Solder lug (radial can) configuration delivers reliable, low-impedance connections suitable for chassis-mounted power sections.
• Engineered endurance: 1000 hours at 85°C specification gives predictable lifetime behavior for elevated-temperature installations.
• Regulatory compliance: RoHS conformity supports environmental and regulatory planning for designs.
