LGN2W221MELA40

The LGN2W221MELA40 is a snap‑in terminal aluminum electrolytic capacitor rated 450V and 220µF, designed for general‑purpose power applications where high voltage handling and sustained ripple performance are required. Built to the Nichicon LGN series specification, it combines a compact φ25×40mm can and snap‑in mounting for robust board installation.

Key value comes from its high rated voltage, substantial ripple current capability at both low and high frequencies, and a 3000‑hour endurance at 105°C, delivering reliable bulk energy storage and filtering over extended operating periods in demanding environments.

Key Features

• Capacitance & Voltage — 220 µF capacitance at a 450 V rated voltage, suitable for high‑voltage bulk storage and filtering in general‑purpose equipment.
• Snap‑In Mounting — Radial, can‑type snap‑in terminals provide secure PCB retention for power module and chassis‑mounted assemblies.
• High Ripple Current — 1.05 A at 120 Hz (low frequency) and 1.502 A at 100 kHz (high frequency), supporting sustained AC ripple and decoupling loads.
• Endurance — Rated for 3000 hours at 105°C under rated ripple and DC bias conditions, meeting the LGN series endurance specification for long life at elevated temperature.
• Electrical Losses — tan δ ≤ 0.20 (measured at 120 Hz, 20°C), reflecting controlled dissipation for stable performance.
• Leakage Current — Typical leakage specified at 940 µA, enabling predictable charge retention and discharge behavior.
• Temperature Range — Specified operating range of −25°C to +105°C for use across a wide set of thermal environments.
• RoHS Compliant & Packaging — Compliant to RoHS; supplied in tray packing for production assembly and handling.

Typical Applications

• Power Supply Filtering — Bulk energy storage and smoothing of high‑voltage rails in general‑purpose power supplies and converters.
• Industrial Power Electronics — Filtering and decoupling in industrial equipment that requires 450V class capacitors with sustained ripple capability.
• DC Link / Energy Storage — Local energy reservoir and ripple mitigation where compact high‑voltage capacitors are needed on power boards.

Unique Advantages

• High Voltage Capability: 450 V rating supports higher‑voltage designs without series stacking, simplifying BOM and layout.
• Dual‑Frequency Ripple Performance: Specified ripple current at both 120 Hz and 100 kHz provides designers with verified performance across common low and high frequency domains.
• Long Endurance at Elevated Temperature: 3000 hours at 105°C endurance rating offers predictable life in thermally demanding applications.
• Compact Snap‑In Form Factor: φ25×40 mm can and snap‑in terminals deliver secure mechanical retention while saving board area compared to larger variants in the LG series.
• Controlled Dissipation and Leakage: tan δ ≤ 0.20 and specified leakage current (940 µA) enable reliable thermal and charge behavior in deployed systems.
• RoHS Compliance: Meets RoHS requirements for environmental and regulatory alignment in manufactured products.
