LKG1J122MESBBK

The LKG1J122MESBBK is an aluminum electrolytic snap-in capacitor from Nichicon's LKG series, engineered for audio equipment where fidelity and stable power filtering are important. It combines a 1200 µF capacitance with a 63 V rating in a compact, snap-in radial can designed for secure panel or chassis mounting in audio applications.

As a Type-II (BK) grade from the LKG family, this part reflects the series' focus on high-grade audio performance and is RoHS compliant.

Key Features

• Capacitance & Voltage — 1200 µF nominal capacitance at a rated voltage of 63 V, with a tolerance of ±20%.
• Audio-grade construction — Part of the LKG series designed specifically for audio equipment, prioritizing high-fidelity sound quality and tone characteristics.
• Snap-in mounting & package — Radial can with snap-in terminals for robust mechanical retention and simplified assembly in chassis or PCB-mounted audio modules.
• Endurance and temperature range — Rated operational lifetime of 1000 hours at 85°C, with an operating temperature range of −40°C to +85°C.
• Leakage and ripple characteristics — Specified leakage current of 820 µA and a ripple current of 1.95 A at 120 Hz, documented for reliable power filtering behavior.
• Compact form factor — Diameter φ30 mm × length 20 mm, suitable for space-constrained audio assemblies.
• Polarized — Standard polarized aluminum electrolytic design for DC filtering and bulk energy storage.
• Regulatory — RoHS compliant, with gold printing on a black sleeve as described in the series marking.

Typical Applications

• High-fidelity audio amplifiers — Bulk smoothing and power-stage decoupling to support clean power delivery in audio amplifier designs.
• Audio power supplies — Filtering and energy storage in regulated and unregulated power supplies used in professional and consumer audio equipment.
• HD audio systems — Component-level choice for equipment where the LKG series' emphasis on tone quality and sound fidelity is required.

Unique Advantages

• Audio-focused design: LKG series engineering targets high-fidelity sound quality, making this part suitable for audio-centric power filtering.
• Higher voltage capability: 63 V rating supports higher-voltage rails found in many audio power stages and supply topologies.
