LKG1C273MESAAK

The LKG1C273MESAAK is a snap‑in aluminum electrolytic capacitor from Nichicon’s LKG series, optimized for audio applications. It combines very high capacitance (27,000 µF) in a radial snap‑in can with specifications aimed at high‑fidelity audio equipment and related systems.

Engineered for audio use, the part provides bulk energy storage and low‑frequency ripple handling in a compact φ25 × 50 mm package, with endurance and temperature ratings sized for demanding consumer and pro‑audio environments.

Key Features

• High Capacitance — 27,000 µF nominal capacitance suitable for bulk storage in audio power circuits; capacitance tolerance ±20%.
• Audio‑Oriented Grade — Part of the LKG series designed for high‑grade audio equipment and HD audio sound quality.
• Rated Voltage — 16 V DC rating for low‑voltage audio power rails.
• Low‑Frequency Ripple Handling — 3.4 A ripple current specified at 120 Hz, enabling effective smoothing under audio load conditions.
• Loss Tangent — tan δ = 0.45 measured at 20°C, 120 Hz to characterize ESR‑related losses.
• Leakage Current — 1,970 µA (specified), consistent with large‑value electrolytic devices.
• Durability & Temperature Range — Rated for operation from −40°C to +85°C with endurance of 1,000 hours at 85°C.
• Mounting & Package — Snap‑in radial can (φ25 × 50 mm) for secure board mounting; available in tray packing for production handling.
• RoHS Compliant — Meets the RoHS directive as noted in the product documentation.

Typical Applications

• High‑grade audio equipment — Intended for use in audio systems where capacitance and stability contribute to sound quality.
• HD audio systems — Targets designs with high fidelity requirements as described in the LKG series documentation.
• Power filtering in audio electronics — Suited for applications that require large bulk capacitance and low‑frequency ripple management within the specified temperature range.

Unique Advantages

• Large bulk capacitance in a compact snap‑in can — 27,000 µF in a φ25 × 50 mm package reduces the board area needed for high‑value storage.
• Designed for audio fidelity — Part of Nichicon’s LKG family, explicitly developed for high‑tone quality and HD audio applications.
• Defined ripple and dissipation characteristics — 3.4 A ripple current at 120 Hz and tan δ specified at 20°C provide measurable behavior for design verification.
• High‑temperature endurance — 1,000 hours at 85°C ensures predictable lifetime performance under specified stress conditions.
• Robust operating range — −40°C to +85°C operation supports a wide variety of consumer and professional audio environments.
• RoHS compliance — Facilitates use in designs that require restricted‑substance compliance.
