LNK2W272MSEGBB

The LNK2W272MSEGBB from Nichicon is an aluminum electrolytic capacitor in a screw-terminal, radial can package. It delivers 2.7 mF (2700 µF) capacitance at a 450 V rating with polarized terminals and is intended for general-purpose applications.

Designed for higher-voltage applications that require a robust electrical connection, this part combines a compact φ63.5 × 95 mm can with screw terminals, a 5000-hour load life at 85 °C, and RoHS compliance to provide repeatable electrical performance within the specified operating envelope.

Key Features

• High Capacitance and Voltage — 2.7 mF (2700 µF) rated at 450 V, delivering significant stored energy in a single component.
• Screw Terminal Mounting — Radial can with screw terminals for secure bolted connections and straightforward mechanical installation.
• Endurance — Rated load life of 5000 hours at 85 °C with applied ripple current according to the datasheet endurance conditions.
• Operating Temperature Range — Specified for operation from −25 °C to +85 °C to match a variety of environmental conditions.
• Ripple Current Capability — 10.5 A at 120 Hz and 14.7 A at 10 kHz, with published frequency coefficients in the series datasheet for scaling to other frequencies.
• Electrical Characteristics — Tolerance ±20% at 120 Hz/20 °C, tan δ of 0.2, and leakage current specified (about 3300 µA per the part description).
• Package and Size — φ63.5 × 95 mm can (listed size L: 9.5 × D: 6.35 cm) with M5 bolt provisions and a radial screw-terminal layout for mounting brackets.
• Regulatory — RoHS compliant.

Typical Applications

• General Purpose — Intended for general-purpose applications requiring 2.7 mF capacitance and a 450 V rating.
• Screw-Terminal Power Assemblies — Suited to designs that require bolted terminal connections and a radial can form factor within the specified temperature range.
• High-Voltage DC Systems — Applicable where a high-voltage electrolytic capacitor with defined ripple current capability and a 5000-hour life at 85 °C is required.

Unique Advantages

• High energy storage in a single part — 2700 µF at 450 V reduces the need for parallel components when high capacitance and voltage are required.
• Secure mechanical and electrical connection — Screw terminal package simplifies installation and provides a reliable bolted connection for heavy-current paths.
• Validated endurance — 5000-hour rated life at 85 °C under rated ripple current offers predictable aging behavior for design planning.
• Clear frequency ripple data — Published ripple current figures at 120 Hz and 10 kHz support thermal and ripple-stress calculations.
• RoHS compliance — Meets directive requirements for restricted substances.
• Compact high-voltage form factor — φ63.5 × 95 mm can provides a balance of size and stored energy for space-constrained power assemblies.
