LHT2W471MELC45

The LHT2W471MELC45 is a snap‑in terminal aluminum electrolytic capacitor designed for general‑purpose high‑voltage applications. It combines a 470 µF capacitance with a 450 V rating and is built for elevated operating conditions, supporting an ambient range of −40°C to 125°C and a 3000‑hour endurance at 125°C.

Its snap‑in can package and polarized design provide a compact bulk energy/storage solution for industrial and commercial equipment that require sustained performance under elevated temperature and ripple stress.

Key Features

• Electrical performance: 470 µF nominal capacitance with ±20% tolerance; rated voltage 450 V provides high‑voltage bulk capacitance for DC link and smoothing roles.
• Ripple current handling: Rated ripple current of 1.91 A at 120 Hz (125°C) and 2.731 A at 50 kHz, enabling effective absorption of AC ripple in high‑stress power circuits.
• Low leakage and loss: Specified leakage current of 1,370 µA and tangent of loss angle (tan δ) ≤ 0.20 at 20°C, 120 Hz, for predictable DC performance and dissipation.
• High‑temperature endurance: Qualified for 3000 hours at 125°C under rated DC bias plus rated ripple current, with defined post‑test limits on capacitance and leakage.
• Wide operating temperature: Rated for −40°C to +125°C to support equipment that experiences wide ambient temperature swings.
• Package & mounting: Snap‑in radial can, size φ35 × 45L (mm), designed for reliable board mounting and robust mechanical retention.
• Environmental compliance: RoHS‑compliant construction.

Typical Applications

• Industrial power supplies: Bulk smoothing and energy storage in high‑voltage power supplies where 450 V rating and high ripple handling are required.
• Power conversion and DC links: DC link smoothing in converters and inverters that operate at elevated temperatures and demand sustained ripple current capability.
• Commercial high‑voltage equipment: General‑purpose high‑voltage circuits in commercial systems that benefit from long endurance at 125°C.

Unique Advantages

• High‑voltage capability: 450 V rating provides margin for high‑voltage DC applications and simplifies system-level design by delivering substantial capacitance at elevated voltage.
• Elevated temperature endurance: 3000 hours at 125°C under rated conditions supports long service life in hot operating environments.
• Robust ripple performance: High rated ripple currents at both low and high frequencies minimize temperature rise and extend service life in ripple‑intensive circuits.
• Compact snap‑in form factor: φ35 × 45L can with snap‑in terminals enables secure board mounting and saves assembly time compared with other heavy‑duty terminations.
• Measurable loss and leakage limits: Specified tan δ and leakage current figures aid in predictable thermal and leakage budgeting during system design.
• RoHS compliant: Meets RoHS requirements for environmental compliance in commercial and industrial product lines.
