LGJ2W470MELY20

The LGJ2W470MELY20 is a Nichicon LGJ series aluminum electrolytic capacitor in a low‑profile, snap‑in terminal radial can. It delivers 47 µF capacitance at a 450 V rating with ±20% tolerance, targeted for general‑purpose power system applications that require high voltage handling in a compact footprint.

Designed for continuous operation up to 105°C and offered in tray packing for mass production, this part balances high‑voltage performance, specified ripple capability, and long endurance for industrial and commercial equipment designs.

Key Features

• Capacitance & Tolerance — 47 µF nominal capacitance with ±20% tolerance at 120 Hz, 20°C.
• High Voltage Rating — Rated for 450 V DC to support high‑voltage power rails and filtering duties.
• Temperature Range & Endurance — Operating range −25°C to 105°C with a specified lifetime of 3000 hours at 105°C.
• Ripple Current Performance — Rated ripple current of 520 mA at low frequency (120 Hz) and 743.6 mA at high frequency (50 kHz), enabling effective AC ripple smoothing in power circuits.
• Low Leakage — Specified leakage current of 430 µA, suitable for applications requiring controlled leakage behavior.
• Loss Characteristics (Series Data) — tan δ specification for 450 V is 0.20 max (measurement: 120 Hz, 20°C), providing an indicator of dissipation factor for design evaluation.
• Package & Mounting — Snap‑in terminal radial can (φ20 × 20 mm), low‑profile design for compact board layouts and robust mechanical mounting.
• Production & Packaging — Available in tray packing and listed as mass production, facilitating volume assembly and procurement.

Typical Applications

• General‑purpose power systems — Filtering and energy storage on high‑voltage DC rails where a 450 V rating and 47 µF value are required.
• Industrial equipment — Bulk decoupling and ripple smoothing in control systems exposed to elevated ambient temperatures up to 105°C.
• Commercial power supplies — Use in high‑voltage stages that benefit from specified ripple current capability and long endurance.

Unique Advantages

• High‑voltage capability: 450 V rating allows direct use on higher DC bus voltages without series stacking.
• Compact, low‑profile package: φ20 × 20 mm can with snap‑in terminals saves board height while providing secure mechanical mounting.
• High‑temperature endurance: 3000 hours at 105°C supports reliable operation in thermally demanding environments.
• Defined ripple handling: Measured ripple current specs at both low and high frequency (520 mA at 120 Hz, 743.6 mA at 50 kHz) allow designers to size components for real operating conditions.
• Controlled leakage: Specified leakage current (430 µA) aids predictable DC behavior in sensitive power designs.
• Production ready: Tray packing and mass production status simplify procurement and high‑volume assembly planning.
