LGU2A222MELC

The Nichicon LGU2A222MELC is a snap‑in terminal aluminum electrolytic capacitor from the LGU series, designed for general‑purpose power applications. It provides 2.2 mF capacitance at a 100 V rating with polarized construction and a snap‑in radial can package for secure PCB mounting.

Engineered for elevated operating temperatures, the LGU2A222MELC is specified for operation up to 105°C and is rated to withstand 3,000 hours of rated ripple current at 105°C, making it suitable for designs that require sustained performance in warm environments.

Key Features

• Electrical Specification — 2.2 mF capacitance at 100 V rated voltage, polarization suitable for DC bulk energy storage and smoothing.
• High‑Temperature Endurance — 105°C standard operating temperature with documented endurance: withstands 3,000 hours application of rated ripple current at 105°C.
• Ripple Current Performance — Supports 2.52 A at 120 Hz and 2.898 A at 50 kHz, enabling effective ripple handling in high‑load power circuits.
• Package & Mounting — Snap‑in terminal, radial can (snap‑in) package for robust mechanical retention on PCBs; physical size approximately L: 3 × D: 3.5 cm.
• Operational Range — Rated for operation from −40°C to +105°C for the 16–250 V variants in the LGU series; this part is specified with operation to 105°C.
• RoHS Compliance — Compliant to the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Power Supply Bulk Filtering — Energy storage and smoothing in AC/DC and DC/DC power supplies where 100 V rating and high capacitance are required.
• Industrial Power Conversion — Filtering and decoupling in motor drives, inverters, and other industrial converters that demand high ripple tolerance and elevated temperature capability.
• UPS and Energy Backup — Short‑term energy buffering and smoothing in uninterruptible power supplies and backup power modules.
• General‑Purpose High‑Temperature Electronics — Use in equipment operating in warm environments up to 105°C where long‑term ripple endurance is needed.

Unique Advantages

• Proven High‑Temperature Endurance: Specified to withstand 3,000 hours of rated ripple current at 105°C, providing predictable aging and performance in hot operating conditions.
• Strong Ripple Handling: Rated ripple currents of 2.52 A (120 Hz) and 2.898 A (50 kHz) support designs with substantial AC components on the DC bus.
• Secure Snap‑In Mounting: Snap‑in radial can package offers reliable mechanical retention for high‑current, high‑vibration assemblies.
• High Capacitance at Elevated Voltage: 2.2 mF at 100 V delivers notable stored energy for bulk filtering without requiring multiple smaller capacitors.
• Regulatory Compliance: RoHS compliance assists in meeting environmental directives for commercial and industrial products.
