LNK2G122MSEF

The LNK2G122MSEF is a screw-terminal aluminum electrolytic capacitor designed for general-purpose applications requiring high capacitance at elevated DC voltages. It is a radial, can-style, screw-terminal device offering 1,200 µF capacitance at a 400 V rating with a compact φ51 × 75 mm package.

Engineered for sustained operation at up to 85°C, the LNK2G122MSEF combines high ripple-current handling and a 5,000 hour endurance at 85°C to support designs that demand reliable DC energy storage and smoothing under continuous ripple load.

Key Features

• Capacitance & Voltage — 1,200 µF nominal capacitance rated at 400 V DC with ±20% tolerance (120 Hz, 20°C).
• Screw Terminal Mounting — Radial can with screw terminals for secure, low-resistance connections suitable for bolted terminals and heavy-current terminations.
• Ripple Current Capability — Low-frequency ripple current 5.8 A at 120 Hz and high-frequency ripple current 8.12 A at 10 kHz, supporting both mains-frequency and higher-frequency ripple environments.
• Loss Characteristics — Tangent of loss angle (tan δ) 0.2 specified at 20°C and 120 Hz to characterize dissipation behavior.
• Leakage Current — Specified leakage current 2,070 µA after rated-voltage application.
• Endurance / Lifetime — Load-life rated for 5,000 hours at 85°C under rated ripple current; meets the LNK series endurance criteria.
• Operating Temperature Range — −25°C to +85°C to cover a broad range of general-purpose environments.
• Compact Form Factor — Physical size φ51 × 75 mm (L: 7.5 cm × D: 5.1 cm) for high-voltage capacitance in a smaller-sized screw-terminal package.
• Regulatory — RoHS compliant.
• Packaging & Availability — Cardboard packing; listed as mass production.

Typical Applications

• General Purpose — High-voltage DC energy storage — Provides 1,200 µF at 400 V for general-purpose designs that require bulk capacitance at elevated DC voltages.
• General Purpose — Secure, high-current terminations — Screw-terminal package supports robust mechanical and electrical connections where bolted terminals are preferred.
• General Purpose — Ripple-current environments — Suited to applications that require handling up to 5.8 A (120 Hz) and 8.12 A (10 kHz) ripple currents.

Unique Advantages

• High-voltage capacitance density: 1,200 µF at 400 V provides substantial DC energy storage in a compact φ51 × 75 mm can.
• Designed for continuous ripple load: Rated ripple currents of 5.8 A (120 Hz) and 8.12 A (10 kHz) reduce the need for parallel components to share ripple duty.
• Long operational endurance: 5,000 hour load-life at 85°C supports prolonged operation under rated ripple and temperature conditions.
• Secure screw-terminal interface: Screw terminals enable low-impedance, mechanically robust connections for high-current or serviceable installations.
• Controlled dissipation: tan δ of 0.2 at 20°C / 120 Hz provides a defined dissipation characteristic for thermal and loss budgeting.
• Compliance and manufacturability: RoHS compliance and cardboard packing reflect environmental compliance and production-ready packaging.
