LKX2D681MESC25

The LKX2D681MESC25 from Nichicon is an aluminum electrolytic, snap‑in terminal capacitor in the LKX series designed for audio equipment and switching power supplies. It delivers substantial bulk capacitance at a 200 V rating with a form factor suited to secure board mounting and high‑ripple applications.

Key value propositions include low dissipation factor for audio use, high ripple current capability across low and high frequencies, and a 2,000‑hour endurance rating at 105°C for sustained operation in elevated temperatures.

Key Features

• Capacitance & Voltage — 680 µF rated at 200 V with ±20% tolerance for bulk energy storage and smoothing.
• Low dissipation (tan δ) — tanδ = 0.15 measured at 20°C, 120 Hz to minimize loss in audio and power‑supply circuits.
• High ripple current capability — 1.75 A at 120 Hz (low frequency) and 2.625 A at 50 kHz (high frequency) to handle demanding filtering loads.
• Leakage current — 1,100 µA specified after rated voltage application conditions.
• Endurance & temperature range — 2,000 hours life at 105°C; operating temperature range −40°C to +105°C.
• Package & mounting — Radial snap‑in can (snap‑in terminal type), polarized construction for secure PCB installation.
• Size — Compact φ35 × 25 mm (D × L) footprint to fit systems needing high capacitance in a modest envelope.
• Compliance & availability — RoHS compliant; supplied in tray packing and available in mass production status.

Typical Applications

• Audio Equipment — Bulk smoothing and power decoupling in audio power supplies where low dissipation at 120 Hz supports signal fidelity.
• Switching Power Supplies — Bulk energy storage and filtering at up to 200 V with ripple current capacity suitable for converter outputs.
• General‑Purpose Power Electronics — Energy storage and decoupling in general‑purpose circuits that require reliable performance from −40°C to +105°C.

Unique Advantages

• Low loss for audio‑centric designs: The low tanδ at 120 Hz reduces dissipation in audio power paths.
• Broad ripple handling across frequency: Specified ripple currents at both 120 Hz and 50 kHz accommodate low‑ and high‑frequency filtering needs.
• High‑temperature endurance: 2,000 hours at 105°C provides predictable life in elevated‑temperature environments.
• Secure, serviceable mounting: Snap‑in radial can package enables robust PCB retention for high‑current assemblies.
• Large capacitance at high voltage: 680 µF at 200 V offers substantial bulk for smoothing, decoupling, and energy buffering.
• Regulatory alignment: RoHS compliance supports usage in regulated product lines.
