LKG1H272MESBCK

The LKG1H272MESBCK is an aluminum electrolytic snap‑in capacitor from Nichicon’s LKG series, engineered for audio applications. It combines a 2.7 mF (2700 µF) capacitance and a 50 V rated voltage in a radial, snap‑in can package optimized for power filtering and energy storage in audio equipment.

Designed as part of the LKG family for high‑grade audio use, this capacitor offers a balance of capacitance density, ripple handling and lifetime performance for designers of amplifiers, power supplies and professional audio subsystems.

Key Features

• Capacitance & Voltage — 2.7 mF (2700 µF) nominal capacitance with a 50 V rated voltage and ±20% tolerance, providing bulk energy storage and DC rail smoothing for audio power circuits.
• Low Loss Characteristic — Specified tan δ of 0.22 (measured at 120 Hz, 20°C), helping to limit dielectric losses in AC ripple environments.
• Ripple Current Handling — 3 A ripple current at 120 Hz, supporting high‑demand power stages and smoothing in audio amplifiers and power supplies.
• Endurance & Temperature Range — Rated for 1000 hours at 85°C and specified for operation from −40°C to +85°C, enabling reliable performance in controlled‑ambient audio enclosures.
• Mechanical & Mounting — Snap‑in terminal, radial can package (φ30 × 45 mm), designed for secure board or chassis mounting and straightforward assembly with tray packing.
• Polarized Device — Electrolytic polarized construction suitable for DC filtering and energy reservoir roles in audio power paths.
• RoHS Compliant — Meets RoHS requirements as noted for the LKG series.

Typical Applications

• Audio Power Supplies — Bulk smoothing and reservoir capacitance for amplifier rails, leveraging 2700 µF and 3 A ripple capability to stabilize DC supplies under dynamic audio loads.
• Amplifier Output Stages — Energy storage and decoupling in high‑fidelity amplifiers where low loss (tan δ 0.22) and stable capacitance over temperature aid sound quality.
• Professional Audio Equipment — Power conditioning in mixers, powered crossovers and studio hardware that require reliable, long‑life electrolytic storage at 50 V.

Unique Advantages

• Audio‑Focused Series Design — Part of Nichicon’s LKG series, which is specified for high‑grade audio use, aligning component behavior with audio system requirements.
• High Bulk Capacitance at 50 V — 2700 µF provides substantial energy storage in a compact snap‑in can, reducing the number of discrete capacitors required on power rails.
• Strong Ripple Capability — 3 A ripple current rating at 120 Hz supports demanding transient currents typical in amplifier power stages.
• Durability at Elevated Temperature — 1000 hours rated life at 85°C offers predictable endurance for equipment expected to operate in warm enclosures.
• Assembly‑Friendly Packaging — Snap‑in radial can and tray packing ease integration into production lines and secure mechanical mounting.
• Regulatory Compliance — RoHS compliance supports designs targeted at markets with material‑use restrictions.
