LGU2C471MELZ

The LGU2C471MELZ is a snap‑in terminal aluminum electrolytic capacitor designed for general‑purpose power applications. It delivers 470 µF capacitance at a 160 V rating in a compact radial can (φ22 × 30L) with a snap‑in mounting style.

Engineered for durability, this part is specified for operation from −40 °C to 105 °C and is rated for 3,000 hours of endurance at 105 °C under rated ripple conditions, making it suitable where sustained high‑temperature ripple performance is required.

Key Features

• Capacitance and Tolerance — 470 µF nominal with a tolerance of −20% to +20% at 120 Hz, 20 °C for predictable bulk energy storage and decoupling.
• Rated Voltage — 160 V DC rating suitable for mid‑voltage power systems and power supply stages.
• High Ripple Endurance — Specified low‑frequency ripple current of 1.55 A (120 Hz) and high‑frequency ripple current of 2.325 A (50 kHz) to support significant AC stress on the capacitor.
• Long Life at Elevated Temperature — Endurance of 3,000 hours at 105 °C with rated DC bias plus rated ripple current; capacitance change, dissipation factor and leakage current limits are specified for post‑test performance.
• Low Loss Characteristic — tan δ (loss tangent) of 0.15 measured at 20 °C, 120 Hz, supporting efficient operation in AC‑stressed environments.
• Leakage Current — Rated leakage current of 820 µA after standard voltage application, aiding predictable discharge behavior in circuits.
• Package and Mounting — Radial can with snap‑in terminals (φ22 × 30L; L: 3.0 cm × D: 2.2 cm) for secure PCB retention and simplified assembly.
• RoHS Compliant — Meets RoHS directive requirements for restricted substances.

Typical Applications

• Power supply bulk smoothing — Provides bulk energy storage and ripple absorption in mid‑voltage power supplies where 160 V rating and high ripple capability are required.
• DC‑link and intermediate bus filtering — Supports DC‑link and bus decoupling applications that demand sustained ripple endurance at elevated temperatures.
• Industrial power electronics — Suitable for general‑purpose industrial designs that require robust electrolytic capacitance in a snap‑in radial package.

Unique Advantages

• Designed for sustained high‑temperature operation — 3,000 hours endurance at 105 °C under rated conditions ensures long service life in thermally demanding installations.
• High ripple handling across frequencies — Specified ripple currents for both low and high frequencies (1.55 A at 120 Hz; 2.325 A at 50 kHz) provide predictable AC stress performance.
• Compact snap‑in package — φ22 × 30L radial can with snap‑in terminals offers sturdy PCB retention and straightforward mechanical integration.
• Controlled electrical characteristics — Low loss tangent (tan δ = 0.15) and defined leakage current (820 µA) support predictable thermal and electrical behavior in designs.
• General‑purpose flexibility — Broad operating temperature range (−40 °C to 105 °C) and general‑purpose designation make the part adaptable across multiple power applications.
