LKG1H272MESCCK

The LKG1H272MESCCK is a snap‑in, large‑can aluminum electrolytic capacitor from Nichicon’s LKG series, engineered for high‑grade audio equipment. It is a polarized, snap‑in radial can designed to prioritize audio fidelity in power supply and filtering roles within audio systems.

Key electrical characteristics include 2.7 mF (2700 µF) capacitance at 50 V, a low‑frequency ripple current rating of 2.95 A (120 Hz), leakage current of 1100 µA, and a tangent of loss angle (tan δ) of 0.22 measured at 20 °C and 120 Hz. The capacitor is specified for operation from −40 °C to +85 °C with an endurance rating of 1000 hours at 85 °C. Note: this part is End Of Life.

Key Features

• Audio‑grade LKG series (TYPE‑III): Designed for high‑grade audio equipment; TYPE‑III grade (CK suffix) reflects the series’ highest tone quality construction, including gold‑plated terminal design as defined in the LKG series documentation.
• Capacitance & voltage: 2.7 mF (2700 µF) nominal capacitance with a rated voltage of 50 V and ±20% tolerance at 120 Hz, 20 °C.
• Low‑frequency ripple handling: 2.95 A ripple current rating at 120 Hz, suitable for smoothing and decoupling in audio power supplies.
• Loss and leakage: Tangent of loss angle (tan δ) specified at 0.22 (20 °C, 120 Hz) and leakage current specified at 1100 µA.
• Mechanical/package: Snap‑in radial can package (φ35 × 35L; L: 3.5 × D: 3.5 cm) supplied in tray packing for board population.
• Temperature & endurance: Operating temperature range −40 °C to +85 °C with a rated lifetime of 1000 hours at 85 °C.
• Environmental compliance: RoHS‑compliant construction.

Typical Applications

• High‑fidelity power supply filtering: Bulk smoothing and ripple suppression in audio amplifier power rails where elevated ripple current capacity is required.
• Preamp and signal chain support: Decoupling and reservoir capacitance in high‑grade audio circuits to preserve low‑noise performance and tonal consistency.
• Audio system power modules: Input/output filtering and energy storage in power supply modules of consumer and professional audio equipment.

Unique Advantages

• Audio‑focused construction: LKG series TYPE‑III grade emphasizes tone quality and terminal treatment, making this part suited for designs where sound character is a priority.
• High ripple capability: 2.95 A ripple current rating at 120 Hz provides durable performance in demanding power‑supply environments.
• Clear, verifiable electrical specs: Specified tan δ (0.22 at 20 °C, 120 Hz) and measured leakage current offer engineers defined parameters for design and simulation.
• Compact large‑can form factor: φ35 can in a snap‑in radial package delivers substantial capacitance in a footprint suitable for power assemblies and audio chassis layouts.
• Temperature endurance: Rated for −40 °C to +85 °C with 1000 hours endurance at 85 °C, providing predictable behavior under elevated operating temperature conditions.
• Tray packing and RoHS compliance: Supplied in tray packing for handling and assembly, with RoHS‑compliant materials for regulatory alignment.

Why Choose LKG1H272MESCCK?
