LKS1J682MESA

The LKS1J682MESA is a snap‑in terminal aluminum electrolytic capacitor from Nichicon’s LKS series, offered in a compact φ25 × 50 mm can. It provides 6.8 mF capacitance at a 63 V rating and is part of a series designed for smaller-sized, audio‑oriented equipment.

Engineered for general‑purpose power filtering and energy storage, this polarized, radial snap‑in capacitor delivers high ripple current capability, defined leakage characteristics, and a rated lifetime under elevated temperature stress for demanding electronic systems.

Key Features

• Capacitance & Voltage — 6.8 mF (6800 µF) nominal capacitance with a 63 V rated voltage and ±20% tolerance for predictable bulk energy storage.
• Snap‑in Radial Can Package — Radial, can‑style snap‑in terminals simplify board mounting and mechanical retention in power assemblies.
• High Ripple Current — Rated ripple current of 3.65 A (120 Hz) to support power‑supply filtering and smoothing under AC ripple conditions.
• Electrical Loss — Specified tan δ of 0.30 (measurement at 120 Hz, 20°C) for defined dissipation characteristics in audio and power circuits.
• Leakage Current — Specified leakage current of 1960 µA, measured per product conditions, for predictable standby and bias behavior.
• Temperature & Lifetime — Operates from −40°C to +85°C with a rated endurance of 1000 hours at 85°C, supporting long‑term operation in moderate temperature environments.
• Mechanical Size & Packing — Can dimensions φ25 × 50 mm (L: 5.0 × D: 2.5 cm) and tray packing for straightforward handling and assembly.
• RoHS Compliant — Conforms to RoHS directive requirements as indicated in the series documentation.

Typical Applications

• Audio Equipment — Bulk filtering and power reservoir in amplifiers and audio power supplies where the LKS series’ smaller form factor is desirable.
• Power Supply Filtering — Smoothing and decoupling in regulated power rails that require high capacitance and substantial ripple handling at 120 Hz.
• Industrial Electronics — Energy storage and transient suppression in control modules and assemblies operating within −40°C to +85°C.

Unique Advantages

• High Energy Density: 6.8 mF in a φ25 × 50 mm can provides substantial bulk capacitance in a compact, snap‑in package.
• Robust Ripple Handling: 3.65 A ripple rating at 120 Hz enables reliable performance in power smoothing and AC‑ridden supply segments.
• Defined Endurance: 1000 hours at 85°C gives designers a quantifiable lifetime target for thermal stress planning and reliability assessments.
• Predictable Dissipation: tan δ = 0.30 and specified leakage current support predictable thermal and standby behavior in audio and power circuits.
• Ease of Assembly: Snap‑in radial can format and tray packing simplify placement and mechanical retention on PCBs.
