LGM2W471MELB40

The LGM2W471MELB40 from Nichicon is a snap‑in terminal, large‑can aluminum electrolytic capacitor in the LGM series. It provides 470 µF capacitance at a 450 V rated voltage in a compact φ30 × 40 mm can designed for equipment downsizing.

Designed for general‑purpose power applications, this RoHS‑compliant capacitor combines high ripple handling, a 105°C rated temperature range, and a 2000‑hour endurance at 105°C to deliver reliable filtering and bulk energy storage in demanding environments.

Key Features

• Capacitance & Voltage — 470 µF nominal capacitance with a 450 V rated voltage for high‑voltage bulk energy storage and smoothing.
• High Temperature Endurance — Rated for operation from −25°C to +105°C with a specified endurance of 2000 hours at 105°C under D.C. bias plus rated ripple current.
• Ripple Current Capability — Rated ripple current of 1000 mArms at 120 Hz (105°C) and 1430 mA at 50 kHz frequency coefficient, supporting both low‑ and high‑frequency ripple demands.
• Loss & Leakage — tanδ ≤ 0.20 (120 Hz, 20°C) and specified leakage current (1,370 µA typical in product data) to characterize dissipation and standby current.
• Snap‑In Packaging — Radial, can‑snap‑in construction (φ30 × 40 mm) in tray packing for robust board mounting and efficient assembly handling.
• Compact Series Design — LGM series offers an ultra‑smaller size (one rank smaller than LGL), enabling equipment downsizing without sacrificing voltage or capacitance.
• RoHS Compliant & In Production — Conforms to RoHS requirements and is available as mass production stock with tray packaging.

Typical Applications

• General‑purpose power filtering — Bulk smoothing and decoupling in equipment that requires 450 V rating and substantial capacitance for stable DC rails.
• Power supply energy storage — Supports high ripple conditions and extended high‑temperature operation for power supply reservoirs and hold‑up capacitors.
• Industrial and commercial equipment — Compact φ30 × 40 mm can and the LGM series’ smaller case size make it suitable where board space and reliability at 105°C matter.

Unique Advantages

• High‑voltage in a compact can — 450 V rating combined with a φ30 × 40 mm footprint enables high‑voltage designs to be more space efficient.
• Designed for elevated temperatures — 2000 hours endurance at 105°C provides predictable performance under prolonged thermal stress.
• Dual‑frequency ripple support — Rated ripple currents specified for 120 Hz and characterized frequency coefficients to support low‑ and high‑frequency ripple environments.
• Predictable electrical characteristics — Specified tanδ (≤ 0.20 at 120 Hz, 20°C) and defined leakage current support accurate loss and standby current planning.
• Assembly‑friendly termination — Snap‑in radial can package in tray packing for reliable PCB mounting and streamlined assembly processes.
