LNT2H331MSEF

The LNT2H331MSEF is a screw‑terminal aluminum electrolytic capacitor rated at 500 V with a nominal capacitance of 330 µF. It is a radial can, screw‑terminal type designed for general‑purpose power applications that require high voltage handling, substantial ripple current capability and elevated operating temperature.

This part delivers a compact φ51 × 80 mm footprint with ±20% capacitance tolerance, low loss (tan δ = 0.2 at 120 Hz), specified leakage current, and RoHS compliance—making it suitable for systems that demand reliable high‑voltage filtering or energy smoothing within the stated environmental and lifecycle limits.

Key Features

• High Voltage Rating — Rated voltage of 500 V supports high‑voltage DC applications requiring robust electrolytic capacitance.
• Capacitance & Tolerance — 330 µF nominal capacitance with ±20% tolerance at 120 Hz, 20 °C for predictable energy storage and filtering performance.
• Screw Terminal Mounting & Package — Radial can with screw terminals (φ51 × 80 mm) for secure, high‑current external connections and chassis or bracket mounting.
• Ripple Current Capability — Specified low‑frequency ripple current of 2.7 A at 120 Hz and high‑frequency ripple current of 3.78 A at 100 kHz to support continuous AC ripple handling under load.
• Low Loss & Leakage — Tangent of loss angle (tan δ) of 0.2 at 120 Hz and measured leakage current of 1210 µA aid in efficient energy dissipation and predictable standby behavior.
• Elevated Temperature Endurance — Operating range –25 °C to +105 °C with a rated load life of 2,000 hours at 105 °C (for this voltage class), supporting sustained operation in hotter environments.
• Regulatory Compliance — RoHS‑compliant construction for use in systems targeting restricted‑substance compliance.

Typical Applications

• General‑purpose power filtering — Bulk smoothing and ripple suppression in systems that require a 500 V, 330 µF polarized capacitor with high ripple capability.
• High‑temperature installations — Applications that operate up to +105 °C and require a capacitor with specified endurance at elevated temperature.
• Chassis‑ or bracket‑mounted power modules — Where a radial can with screw terminals and a φ51 × 80 mm footprint provides robust mechanical and electrical connection.

Unique Advantages

• High‑voltage capability: The 500 V rating enables use in higher DC bus or filtering roles without series stacking.
• Robust ripple performance: Specified ripple currents at both 120 Hz and 100 kHz support a range of power frequencies and switching environments.
• Designed for elevated operating temperature: Rated for –25 °C to +105 °C with a 2,000‑hour life at 105 °C for consistent long‑term behavior in warm conditions.
• Screw‑terminal reliability: Screw terminals deliver secure, low‑impedance connections suitable for higher current paths and repeated installation.
• Predictable electrical characteristics: Defined tan δ and leakage current values enable accurate thermal and loss budgeting in system design.
• RoHS compliant: Meets restricted‑substance requirements for broad regulatory acceptance.
