LNT1K472MSEN

The LNT1K472MSEN is a screw‑terminal aluminum electrolytic capacitor in a radial can package, rated 80 V and 4700 µF (4.7 mF) with ±20% tolerance. It is designed for general‑purpose power applications that require high capacitance, secure screw‑terminal connections, and operation across a wide temperature range.

Key value propositions include robust screw‑terminal mounting for reliable electrical connections, rated ripple current performance at both low and high frequencies, and defined lifetime performance at elevated temperature (2000 hours at 105°C).

Key Features

• High Capacitance, High Voltage — 4700 µF (4.7 mF) nominal capacitance at a rated voltage of 80 V, suitable where substantial bulk energy storage or filtering is required.
• Reliable Screw‑Terminal Package — Radial can with screw terminals provides a mechanically secure, low‑impedance connection for high‑current systems.
• Ripple Current Performance — Rated ripple current of 3.5 A at 120 Hz and 4.025 A at 100 kHz to support AC ripple handling in power systems.
• Defined Electrical Losses — Specified tangent of loss angle (tan δ) of 0.2 for predictable dissipation characteristics.
• Leakage Current — Specified leakage current of 1830 µA consistent with the part’s capacitance and voltage rating.
• Temperature and Lifetime — Operates from −40°C to +105°C with a rated life of 2000 hours at 105°C under rated ripple conditions.
• Compact Screw‑Terminal Form Factor — Physical dimensions φ35 × 80 mm (L: 8.0 × D: 3.5 cm) for systems requiring a high‑capacitance, screw‑mounted can‑type capacitor.
• Environmental Compliance — RoHS‑compliant construction.

Typical Applications

• Power Supplies — Bulk smoothing and filtering in medium‑voltage power supplies where 80 V rating and high capacitance are required.
• Industrial Power Electronics — Energy storage and ripple suppression in industrial converters and controllers that benefit from screw‑terminal connections for robust mounting.
• UPS and Backup Systems — Bulk capacitance for short‑term energy buffering and stabilization in backup power modules.
• Motor Drives and Inverters — DC link or intermediate bus filtering where a combination of 80 V rating, high capacitance, and rated ripple current is needed.

Unique Advantages

• Screw‑terminal security: Provides mechanically robust, low‑resistance connections suited to high‑current or vibration‑prone environments.
• High energy density at 80 V: 4700 µF capacitance supplies substantial bulk energy storage in a compact φ35 × 80 mm can.
• Predictable thermal performance: Rated for −40°C to +105°C operation with defined 2000‑hour life at 105°C for planning system maintenance and replacement intervals.
• Frequency‑aware ripple capability: Specified ripple current values at 120 Hz and 100 kHz allow designers to size the capacitor for both low‑ and high‑frequency ripple conditions.
• Defined loss and leakage characteristics: tan δ of 0.2 and specified leakage current (1830 µA) support thermal and leakage budgeting in design margins.
• Regulatory compliance: RoHS compliance for use in designs requiring restricted‑substance conformity.
