LKG1K122MESAAK

The LKG1K122MESAAK is a snap‑in, radial aluminum electrolytic capacitor from Nichicon’s LKG series, optimized for audio equipment. It delivers 1200 µF capacitance at an 80 V rating in a compact φ25 × 25 mm can with snap‑in mounting for secure PCB installation.

Designed within the LKG family’s audio‑focused grades (Type‑I / "Gold Tune"), this part is specified for audio and high‑fidelity equipment, offering defined performance at 120 Hz and an operating temperature range of −40 °C to +85 °C.

Key Features

• Core Electrical — 1200 µF capacitance with ±20% tolerance (measured at 120 Hz, 20 °C) and an 80 V rated voltage, suitable for medium‑voltage audio circuits.
• Audio‑Oriented Grade — Type‑I (AK) designation in the LKG series, developed specifically for high‑grade audio use and prioritizing tone quality.
• Ripple and Loss Characteristics — Low‑frequency ripple current rating of 1.9 A at 120 Hz and a tangent of loss angle (tanδ) of 0.25 (20 °C, 120 Hz), providing defined AC performance for power filtering in audio supplies.
• Reliability & Endurance — Rated for 1000 hours at 85 °C with specified end‑of‑life limits for capacitance, tanδ and leakage current; leakage current specified at 920 µA.
• Mechanical & Mounting — Snap‑in, radial can package (φ25 × 25 mm) designed for secure board mounting and straightforward assembly; supplied in tray packing.
• Environmental Compliance — RoHS‑compliant construction as specified for the LKG series.

Typical Applications

• High‑grade Audio Amplifiers — Bulk and reservoir capacitance for amplifier power rails where audio‑oriented component selection is required.
• Professional Audio Power Supplies — Filtering and smoothing in power supplies for mixers, preamps and studio equipment, leveraging the 80 V rating and 1.9 A ripple capability.
• Audio Signal and Power Filtering — Decoupling and low‑frequency filtering in high‑fidelity audio circuits where stable capacitance and controlled tanδ at 120 Hz are needed.

Unique Advantages

• Audio‑focused design: Type‑I ("Gold Tune") LKG grade engineered for tone quality in high‑fidelity equipment, aligning component selection with audio performance goals.
• High voltage headroom: 80 V rating enables use in medium‑voltage audio supply designs without stepping up to larger form factors.
• Defined ripple handling: 1.9 A ripple current at 120 Hz supports robust smoothing in audio power stages.
• Compact, secure mounting: Snap‑in radial can in a φ25 × 25 mm footprint simplifies PCB layout and mechanical retention for production assembly.
• Specified endurance: 1000 hours at 85 °C endurance specification allows designers to plan for stable operation under defined thermal stress.
• Regulatory compliance: RoHS‑compliant materials align with common environmental requirements.
