LNK2H103MSEJ

The LNK2H103MSEJ is an aluminum electrolytic capacitor in a screw-terminal radial can designed for general-purpose high-voltage applications. It provides 10,000 µF capacitance at a 500 V rating with polarized terminals and a ±20% tolerance.

Engineered for sustained operation up to 85°C, the device offers long-duration endurance (5,000 hours at 85°C under rated ripple current) and specified ripple current performance across low and high frequencies, making it suitable where high bulk capacitance and reliable terminal connections are required.

Key Features

• Capacitance & Voltage — 10,000 µF nominal capacitance with a 500 V rated voltage and ±20% tolerance (120 Hz, 20°C).
• Package & Mounting — Radial can with screw terminals for secure electrical and mechanical attachment; package dimension provided as φ90 × 235 mm (L: 23.5 × D: 9 cm).
• Polarized Design — Polar capacitor construction for DC bulk storage and filtering applications.
• Operating Temperature — Specified operating range from −25°C to +85°C.
• Load Life / Reliability — Endurance rating of 5,000 hours at 85°C when subjected to D.C. bias plus rated ripple current.
• Ripple Current Capability — Rated ripple current: 29.3 A at 120 Hz and 41.02 A at 10 kHz; frequency coefficients defined for other frequencies in the series datasheet.
• Leakage & Insulation — Leakage current limited to 3√(C·V) µA or 5 mA (whichever is smaller) after 5 minutes at rated voltage; insulation resistance >100 MΩ at DC 500 V between terminal and bracket.
• Regulatory — RoHS compliant.

Typical Applications

• General Purpose — For systems that require large-value, high-voltage capacitors with screw-terminal mounting and polarized construction.
• High-Ripple Environments — Suitable where sustained ripple current is present, supported by specified ripple current ratings at 120 Hz and 10 kHz and a 5,000-hour endurance at 85°C.
• Chassis and Panel Installations — Screw terminals and radial can form factor (φ90 × 235 mm) enable secure mounting using standard brackets as documented in the series dimensions.

Unique Advantages

• High Voltage Bulk Capacitance: 10,000 µF at 500 V provides substantial energy storage per component, reducing the need for parallel devices where space and terminal robustness matter.
• Robust Screw-Terminal Connectivity: Screw terminals offer secure, low-resistance connections for high-current paths and simplified field installation.
• Endurance under Thermal Stress: Rated 5,000 hours at 85°C under rated ripple current delivers predictable aging and lifecycle behavior for thermal-constrained designs.
• Clearly Defined Ripple Performance: Explicit ripple current ratings at both 120 Hz and 10 kHz allow designers to size capacitors against expected AC stress and frequency content.
• Insulation and Leakage Controls: Specified leakage-current limits and >100 MΩ insulation resistance at DC 500 V help maintain performance and safety margins in high-voltage assemblies.
• Regulatory Compliance: RoHS compliance supports use in regions and products requiring restricted substance adherence.
