LKG1H122MESYCK

The LKG1H122MESYCK is a snap‑in aluminum electrolytic capacitor from Nichicon’s LKG series, engineered for audio equipment. This polarized, radial can capacitor combines a 1200 µF capacitance with a 50 V rating and audio‑focused construction to support power supply smoothing and decoupling in high‑fidelity systems.

Designed for demanding audio applications, the part offers measurable characteristics—tan δ, leakage current, ripple current and endurance—that make it suitable where stable filtering and audible performance matter.

Key Features

• Capacitance & Tolerance — 1.2 mF (1200 µF) with tolerance −20% to +20% (measured at 120 Hz, 20°C).
• Rated Voltage — 50 V nominal working voltage for common audio power rails.
• Audio‑Focused LKG Series (TYPE‑III) — Part code suffix "CK" designates TYPE‑III (Super Through) grade in the LKG series, developed for high‑grade audio equipment and high‑tone quality.
• Low‑Frequency Ripple Current — 1.95 A at 120 Hz, enabling effective filtering of low‑frequency ripple in amplifier and supply circuits.
• Loss Tangent (tan δ) — 0.22 at 20°C, 120 Hz, providing a quantified dissipation characteristic for audio designers.
• Leakage Current — 730 μA (specified), useful for estimating standby loss and bias behavior.
• Endurance & Temperature Range — Rated for 1000 hours at 85°C; operating range −40°C to +85°C.
• Package & Mounting — Snap‑in radial can (φ20 × 40 L), tray packing for production handling and secure snap‑in board retention.
• RoHS Compliant — Conforms to applicable RoHS directives as noted for the LKG series.

Typical Applications

• Power supply smoothing for audio amplifiers — 1200 µF and 1.95 A ripple capability help stabilize amplifier rails and reduce low‑frequency ripple audible in outputs.
• Professional audio equipment — Designed for high‑grade audio use where tonal clarity and stable filtering are important (mixing consoles, preamps, signal processors).
• Decoupling in audio electronics — Polarized snap‑in mounting provides secure placement for bulk decoupling in compact audio boards and chassis.

Unique Advantages

• Audio‑centric design: Part of Nichicon’s LKG series developed with priority on high‑fidelity sound quality, aiding tonal performance in audio signal chains.
• Quantified electrical characteristics: Specified tan δ, leakage and ripple current let designers model thermal and noise behavior precisely.
• Robust thermal endurance: 1000 hours at 85°C provides predictable life limits for power electronics in continuous‑use audio systems.
• Snap‑in radial package: Secure mechanical retention and tray packing simplify assembly for production builds.
• RoHS compliance: Aligned with RoHS requirements for environmentally restricted substances.
