LGU1C223MELC

The LGU1C223MELC from Nichicon is a snap‑in terminal aluminum electrolytic capacitor designed for general‑purpose power applications. It provides 22 mF of capacitance at a 16 V rating in a radial, can‑style snap‑in package and is polarized for DC use.

Engineered for elevated operating temperatures, this part is specified to operate from –40°C to +105°C and withstand 3000 hours of rated ripple current application at 105°C. It is RoHS‑compliant for use in regulated environments.

Key Features

• Capacitance & Voltage — 22 mF capacitance with a rated voltage of 16 V and capacitance tolerance of ±20% (–20% to +20%).
• High‑temperature endurance — Endurance specified as 3000 hours at 105°C with D.C. bias plus rated ripple current; after the test the capacitance change is within ±20% and leakage current remains within initial limits.
• Ripple current capability — Rated ripple current values include 3.25 A at 120 Hz and 3.737 A at 50 kHz, supporting demanding power‑filtering duties.
• Wide operating temperature — Specified operating range from –40°C to +105°C for reliable operation across typical industrial and consumer temperature conditions.
• Mechanical & mounting — Snap‑in terminal, radial can package for secure board mounting; physical dimensions listed as L: 3 × D: 3.5 cm for PCB and enclosure planning.
• Electrical characteristics — Tangent of loss angle (tan δ) max. for 16 V is 0.50 (measured at 120 Hz, 20°C). Leakage current is specified as I ≤ 3·C·V (μA) after 5 minutes at 20°C.
• Compliance — Conforms to the RoHS directive (2011/65/EU, (EU)2015/863).
• Polarized — Designed for polarized DC applications; observe polarity during assembly.

Typical Applications

• Power supply smoothing and filtering — Bulk capacitance for smoothing DC rails and reducing ripple in general‑purpose power supplies.
• Energy storage / bulk decoupling — Provides bulk energy reservoir for converters and intermediate DC links where high ripple endurance and elevated temperature performance are required.
• Industrial and consumer equipment — General‑purpose use in equipment that requires a robust snap‑in electrolytic capacitor with long endurance at 105°C.

Unique Advantages

• Long high‑temperature endurance: Rated for 3000 hours at 105°C under rated ripple, enabling reliable life in hotter operating environments.
• High ripple capability: Specified ripple currents (3.25 A at 120 Hz, 3.737 A at 50 kHz) support demanding filtering duties in power electronics.
• Robust thermal range: –40°C to +105°C operation supports a wide span of installation environments without derating outside the specified range.
• Practical snap‑in form factor: Radial, snap‑in can simplifies board mounting for applications that require secure mechanical retention and ease of assembly.
• Clear electrical limits: Defined tan δ and leakage current specifications allow predictable AC and DC performance characterization for design validation.
• RoHS compliant: Meets current RoHS requirements for regulated markets and manufacturing processes.
