LGL2W221MELA35

The LGL2W221MELA35 is a snap‑in terminal aluminum electrolytic capacitor from Nichicon's LGL series, rated at 220 µF and 450 V. Designed for general-purpose power applications, it combines high-voltage capability with a compact 25 mm × 35 mm can and snap‑in mounting for secure PCB retention.

This part delivers engineering-grade endurance and stability with a 2000‑hour life rating at 105°C, controlled dissipation factor, and defined ripple and leakage characteristics suitable for demanding power circuits that require reliable bulk capacitance at elevated temperatures.

Key Features

• High Voltage Rating — Rated for 450 V to support applications requiring elevated DC bus voltages.
• Nominal Capacitance & Tolerance — 220 µF with ±20% tolerance at 120 Hz and 20°C, providing predictable bulk energy storage.
• Temperature and Endurance — Operates from −25°C to +105°C with 2000 hours endurance at 105°C under rated ripple and DC bias.
• Ripple Current Capability — 850 mA at 120 Hz (low frequency) and 1.216 A at 50 kHz (high frequency), enabling effective handling of AC ripple in power stages.
• Low Leakage and Loss — Specified leakage current around 940 µA and tan δ ≤ 0.20 (measured at 20°C, 120 Hz) for controlled losses.
• Compact Snap‑in Package — Radial can, snap‑in mounting (∅25 × L35 mm) for secure mechanical retention and straightforward assembly in power modules.

Typical Applications

• General-purpose power systems — Bulk smoothing and energy storage where a 450 V, 220 µF capacitor with 105°C endurance is required.
• Power supply filtering — DC link and post‑rectification smoothing benefiting from the part's high ripple current capability and defined dissipation factor.
• Industrial converters and inverters — Applications that need reliable high‑voltage capacitance with long life at elevated operating temperatures.
• Electronics requiring secure mounting — Snap‑in terminal design for robust mechanical retention in vertically oriented power assemblies.

Unique Advantages

• High-voltage bulk capacitance: 220 µF at 450 V provides substantial stored energy for DC bus and smoothing applications without increasing footprint excessively.
• Designed for elevated temperature operation: 2000 hours endurance at 105°C ensures predictable lifetime under typical high‑temperature power conditions.
• Balanced electrical performance: Low leakage (~940 µA) and a controlled tan δ (≤0.20) help manage standby losses and thermal rise in dense power designs.
• Broad ripple handling: Rated ripple current figures for both low and high frequency (850 mA at 120 Hz, 1.216 A at 50 kHz) support mixed-frequency ripple environments.
• Compact snap‑in form factor: 25 mm diameter × 35 mm length in a radial, snap‑in can simplifies board layout while delivering secure mounting.
