LKG1K122MESABK

The LKG1K122MESABK is an aluminum electrolytic, snap‑in terminal capacitor from Nichicon’s LKG series designed for audio equipment. It provides 1,200 µF capacitance at an 80 V rating in a radial, snap‑in can package and is intended where audio‑grade filtering and DC bus smoothing are required.

Built to the LKG series specifications, this TYPE‑II (BK) grade part targets sound‑quality‑sensitive applications while delivering defined endurance and environmental performance: −40 °C to +85 °C operating range and 1,000 hours endurance at 85 °C.

Key Features

• Capacitance & Tolerance — 1.2 mF (1,200 µF) with ±20% tolerance at 120 Hz, 20 °C, suitable for bulk energy storage and smoothing in audio power stages.
• Rated Voltage & Polarization — 80 V rated, polarized aluminum electrolytic design for higher‑voltage audio supply rails.
• Termination & Package — Snap‑in terminal, radial can (φ25 × 35 mm), tray packing for through‑panel or chassis mounting and secure mechanical retention.
• Audio‑Focused Series Grade — TYPE‑II (BK) designation in the LKG series (center grade) aimed at delivering the series’ targeted sound quality characteristics for audio equipment.
• Ripple & Leakage — Low‑frequency ripple current rated 2.3 A at 120 Hz; leakage current listed at 920 µA in the product data for initial conditions.
• Temperature & Reliability — Operating range −40 °C to +85 °C with endurance specified as 1,000 hours at 85 °C (capacitance change within ±20%, tan δ ≤ 200% of initial, leakage current ≤ initial specified value after test).
• Compliance & Marking — RoHS‑compliant; marked with gold‑color lettering on a black sleeve per series marking convention.

Typical Applications

• High‑fidelity audio equipment — Bulk supply smoothing and decoupling in power supplies and amplifier circuits where audio performance matters.
• Power supply filtering for audio amplifiers — 1,200 µF capacitance and 80 V rating support DC bus filtering in medium‑voltage audio power stages.
• Audio system power reservoirs — Snap‑in mounting and rated ripple current capacity enable reliable energy storage for transient demands in speaker and amplifier systems.

Unique Advantages

• Audio‑oriented grade (TYPE‑II BK): The LKG series TYPE‑II code (BK) identifies the center grade focused on sound quality for multiple use in audio equipment.
• High voltage capability: 80 V rating provides headroom for higher‑voltage audio supply designs.
• Robust ripple handling: 2.3 A ripple current at 120 Hz suits low‑frequency power filtering common in amplifier supplies.
• Proven endurance: Specified 1,000 hours at 85 °C with defined limits on capacitance change, tan δ and leakage current supports predictable lifetime performance.
• Secure snap‑in mounting: Radial, snap‑in can enables solid mechanical retention for chassis or panel installations and practical assembly handling.
• Regulatory compliance: RoHS‑compliant construction and series marking practices (gold on black sleeve) simplify identification and compliance tracking.
