LKS1V273MESC

The LKS1V273MESC is a snap‑in aluminum electrolytic capacitor from Nichicon's LKS series, offering high bulk capacitance (27,000 µF) in a radial snap‑in can (φ35 × 50 mm). It is designed for general‑purpose power filtering and is explicitly specified for audio equipment where a smaller-sized, tone-quality‑oriented solution is desired.

Key electrical characteristics include a 35 V rated voltage, low‑frequency ripple handling of 4.8 A at 120 Hz, a leakage current spec of 2,910 µA, and an endurance rating of 1,000 hours at 85 °C. Operating temperature range is −40 °C to +85 °C. Status: End Of Life.

Key Features

• High Capacitance — 27,000 µF (27 mF) nominal capacitance provides large charge storage for power supply smoothing and bulk filtering.
• Rated Voltage — 35 V working voltage suitable for mid‑voltage rail applications.
• Ripple Current Handling — Low‑frequency ripple current rated at 4.8 A (120 Hz) to support substantial ripple suppression in power stages.
• Endurance and Stability — Specified life of 1,000 hours at 85 °C with defined limits for capacitance change, tan δ, and leakage current after endurance testing.
• Loss Tangent (tan δ) — tan δ = 0.4 measured at 20 °C, 120 Hz, useful for evaluating dissipation and AC performance.
• Operating Temperature Range — −40 °C to +85 °C for use across a broad range of ambient conditions.
• Package & Mounting — Radial, snap‑in can (φ35 × 50 mm) for secure mechanical mounting and quick board assembly.
• Polarized Electrolytic — Designed as a polarized capacitor; observe polarity during installation.
• RoHS Compliant — Meets RoHS directive requirements.

Typical Applications

• Audio Equipment — Bulk filtering and decoupling in audio power supplies where the LKS series is specified for smaller size and tone‑quality improvement.
• General‑Purpose Power Filtering — Smoothing and energy storage in power supply rails for industrial and electronic assemblies requiring high capacitance.
• High‑Capacitance Energy Reservoirs — Local energy storage for circuits that need transient current support within the component's voltage and temperature ratings.

Unique Advantages

• Large stored energy in compact form: 27,000 µF in a φ35 × 50 mm snap‑in can provides substantial capacitance without requiring multiple smaller capacitors.
• Practical ripple capability: 4.8 A rated low‑frequency ripple current (120 Hz) reduces the need for parallel devices to handle AC stress.
• Defined endurance: 1,000 hours at 85 °C with post‑test limits for capacitance, tan δ and leakage current gives predictable aging behavior for design planning.
• Audio‑focused series design: LKS series positioning for audio equipment and smaller sizes supports upgrades where tone quality is a consideration.
• Wide ambient range: −40 °C to +85 °C operating range covers many commercial and industrial environments.
• Regulatory compliance: RoHS compatibility supports regulatory and supply‑chain requirements.
