LNK2W123MSEJBN

The LNK2W123MSEJBN from Nichicon is a screw-terminal aluminum electrolytic capacitor in the LNK series designed for general-purpose high-voltage DC applications. Its radial can construction with screw terminals provides a robust connection method for high-capacitance installations.

With a rated voltage of 450 V and 12,000 µF capacitance, this part targets systems that require bulk energy storage and smoothing with long operational life and defined ripple performance. Key technical attributes include a 5,000 hour load life at 85°C, measurable ripple current ratings, and RoHS compliance.

Key Features

• Capacitance & Voltage — 12,000 µF (12 mF) rated capacitance at 450 V for large bulk-storage requirements.
• Screw Terminal, Radial Can Package — Screw terminal mounting and radial can (screw terminals) package provide secure, serviceable connections for heavy-duty installations.
• Load Life — Designed for 5,000 hours operation at 85°C when subjected to rated ripple current, supporting extended service intervals.
• Operating Temperature Range — Specified for −25°C to +85°C operation to cover a broad set of environmental conditions.
• Ripple Current Performance — Rated ripple current of 29.7 A at 120 Hz and 41.58 A at 10 kHz, enabling effective AC ripple handling for power systems.
• Leakage Current — Specified leakage current of 5,000 µA (5000 µA) after application of rated voltage.
• Dielectric Loss — Tangent of loss angle (tan δ) specified at 0.2 to indicate dissipation characteristics at the measurement conditions.
• Dimensions — Size L: 19 × D: 9 cm with a maximum seated height of 7.48 inches, suitable for chassis- or bracket-mounted installations.
• Environmental Compliance — RoHS compliant.

Typical Applications

• Industrial and commercial power supplies — Bulk smoothing and energy storage in 450 V DC supplies where large capacitance and defined ripple handling are required.
• Power conversion and DC-link circuits — Energy buffering and ripple mitigation for converters using a radial screw-terminal capacitor with high ripple ratings.
• General-purpose high-voltage systems — Use in systems requiring a 12,000 µF capacitor with a 5,000 hour rated life at elevated temperature.

Unique Advantages

• High-voltage bulk capacitance: Provides 12,000 µF at 450 V for substantial energy storage in a single component.
• Screw-terminal reliability: Screw-terminal connection supports secure, low-resistance electrical and mechanical attachment for demanding installations.
• Defined long-term endurance: Rated for 5,000 hours at 85°C under ripple load, enabling predictable service life planning.
• Measured ripple capability: Explicit ripple current ratings (29.7 A @ 120 Hz, 41.58 A @ 10 kHz) allow designers to match capacitor selection to system ripple demands.
• Clear electrical loss metric: tan δ specified at 0.2 for direct reference when assessing dielectric losses in design calculations.
• Compliance and fit: RoHS compliance and a defined radial can footprint (L: 19 × D: 9 cm) ease integration into regulated production environments.
