LNK2H392MSEJBB

The LNK2H392MSEJBB is a screw-terminal aluminum electrolytic capacitor designed for general-purpose power applications that require high capacitance at high voltage. It delivers 3.9 mF of capacitance at a 500 V rating in a radial can with screw terminals and is specified for -25°C to 85°C operation.

Key value propositions include high-voltage capacitance in a robust screw-terminal package, load-life endurance under ripple conditions, and manufacturing readiness with cardboard-packed mass-production supply.

Key Features

• High Voltage, High Capacitance — 3.9 mF nominal capacitance with a 500 V rated voltage and ±20% tolerance, suitable where substantial stored energy at high voltage is required.
• Endurance under Ripple — Specified load life of 5000 hours at 85°C when DC bias plus rated ripple current is applied, demonstrating long-term stability in ripple-loaded power circuits.
• Ripple Current Capability — Rated ripple current values include 14.4 A at 120 Hz and 20.16 A at 10 kHz, with frequency coefficients defined across common mains and high-frequency bands to guide ripple derating.
• Electrical Loss and Leakage — Tangent of loss angle (tan δ) specified at 0.2 and leakage current documented as 4180 µA, supporting predictable loss and self-discharge characteristics.
• Insulation and Voltage Proof — Insulation resistance greater than 100 MΩ at DC 500 V between terminal and bracket, and AC 2500 V dielectric proof for one minute with no abnormalities.
• Package and Mounting — Radial can with screw terminals, physical dimension approximately φ90 × 120 mm (L: 12 cm × D: 9 cm), and available mounting bracket dimensions for secure mechanical installation.
• Operating and Environmental — Rated temperature range -25°C to +85°C and RoHS-compliant construction; supplied in cardboard packing for production handling.

Typical Applications

• High-Voltage Power Supplies — Bulk energy storage and smoothing where 500 V rated capacitance and ripple endurance are required.
• Industrial Power Conversion — DC bus filtering and ripple handling in converters and inverters that operate with sustained ripple currents.
• Energy Storage Modules — Applications requiring high-voltage capacitance in a screw-terminal can for secure electrical connections and mechanical mounting.

Unique Advantages

• High-voltage capacitance in a screw-terminal can: Provides substantial energy storage at 500 V with robust screw connections for reliable high-current terminations.
• Validated ripple endurance: 5000-hour load-life rating at 85°C under DC bias plus rated ripple current, enabling predictable lifecycle planning in ripple-stressed designs.
• Frequency-aware ripple handling: Published ripple current values and frequency coefficients allow designers to size and derate the capacitor across 50 Hz up to 10 kHz operating conditions.
• Measured loss and leakage figures: Specified tan δ and leakage current numbers support accurate thermal and self-discharge modeling in system designs.
• Production-ready packaging: Cardboard packing and mass-production availability simplify procurement and scale-up for volume builds.
• Regulatory compliance: RoHS status is compliant, supporting use in regulated electronics assemblies.
