LKG1H272MESYAK

The LKG1H272MESYAK is an aluminum electrolytic, snap-in terminal capacitor from Nichicon's LKG series, specified at 2700 µF and 50 V with ±20% tolerance. It is part of the LKG family designed for audio use and high-fidelity equipment.

With a 2 A ripple-current rating at 120 Hz, a measured tan δ of 0.3, a -40 °C to +85 °C operating range, and a 1000-hour endurance at 85 °C, this component is intended for board-level power filtering and energy storage in demanding audio applications where stable performance and reliability are required.

Key Features

• Capacitance & Voltage — 2.7 mF (2700 µF) rated at 50 V, suitable for mid-voltage audio power rails and bulk filtering.
• Tolerance & Polarization — ±20% capacitance tolerance and polarized construction for predictable filter-design margins.
• Low-loss Characteristic — Tangent of loss angle (tan δ) specified at 0.3 (measurement reference: 120 Hz, 20 °C), supporting audio-frequency performance expectations.
• Ripple Handling — Ripple current rating of 2 A at 120 Hz to support power-supply smoothing in amplifier and preamplifier circuits.
• Leakage Current — Specified leakage current parameters included (product data lists 1100 µA), useful for bias and standby calculations.
• Endurance & Temperature Range — Rated for 1000 hours at 85 °C and operational from -40 °C to +85 °C for long-term stability under elevated temperature stress.
• Package & Mounting — Snap-in, radial can package (approx. φ20 × 35 mm) for secure board mounting and reliable mechanical retention in chassis-mounted or PCB-mounted audio power supplies.
• Environmental Compliance — RoHS compliant per product data.

Typical Applications

• High-fidelity audio amplifiers — Bulk filtering and power smoothing for amplifier rails to support clean power delivery in audio signal chains.
• Preamp and DAC power supplies — Energy storage and decoupling in sensitive analog stages where stable supply helps maintain audio quality.
• Audio power distribution modules — Local energy reservoir and ripple suppression in multi-rail audio systems and powered speaker assemblies.

Unique Advantages

• Audio-focused design — LKG series is specified for audio use and high-grade audio equipment, aligning the component with fidelity-conscious designs.
• High ripple capability — 2 A ripple rating at 120 Hz supports demanding smoothing requirements without excessive heating.
• Compact snap-in can — φ20 × 35 mm footprint offers a balance of capacitance and space efficiency for board- and chassis-mounted audio power circuits.
• Endurance under elevated temperature — 1000 hours at 85 °C provides a defined qualification for lifetime planning in sustained thermal environments.
• Clear electrical specs for design — Specified tan δ, leakage current, and tolerance simplify verification and simulation of power and bias behavior in audio circuits.
• RoHS compliance — Meets RoHS requirements noted in the product data for regulatory alignment.
