LGN2Z222MELC40

The LGN2Z222MELC40 from Nichicon is a snap‑in, radial can aluminum electrolytic capacitor in the LGN series designed for general‑purpose applications. It delivers 2.2 mF capacitance at a 180 V rating with a polar construction and is built for elevated‑temperature operation up to 105°C.

This part combines a compact snap‑in package with proven endurance—capable of withstanding 3000 hours of rated ripple current at 105°C—making it suitable for designs that require robust bulk capacitance and sustained ripple handling in demanding thermal environments.

Key Features

• Capacitance & Voltage — 2.2 mF capacitance rated at 180 V provides substantial bulk energy storage for general‑purpose power circuits.
• Snap‑In Radial Can Package — Snap‑in terminal type in a radial can package for secure chassis or board mounting and straightforward mechanical installation.
• High Temperature Endurance — Rated for operation to 105°C and specified to withstand 3000 hours application of rated ripple current at 105°C, supporting reliable performance in elevated temperature environments.
• Ripple Current Ratings — Specified ripple current of 2.9 A at 120 Hz and 4.35 A at 100 kHz, enabling effective handling of both low‑ and high‑frequency ripple conditions.
• Operating Range — Polarized device with an operating temperature range from −40°C to +105°C and capacitance tolerance of ±20%.
• Environmental Compliance — Compliant with RoHS directives (2011/65/EU, (EU)2015/863).
• Compact Footprint — Smaller case sizing within the LGN series (one rank smaller than LGU), providing space savings for systems where board/chassis real estate is constrained.

Typical Applications

• General‑purpose power filtering — Bulk smoothing and energy storage in power supply circuits that require a 180 V, 2.2 mF capacitor.
• Industrial equipment — Use in general industrial systems where sustained ripple handling and operation up to 105°C are required.
• Power conversion modules — Bulk capacitance for converters and intermediate DC link applications within the specified voltage and temperature limits.

Unique Advantages

• Proven high‑temperature endurance: Specified to withstand 3000 hours of rated ripple at 105°C, supporting longevity in hot operating conditions.
• Clear ripple specifications: Published ripple current values at both 120 Hz (2.9 A) and 100 kHz (4.35 A) allow designers to size the capacitor confidently for expected ripple loads.
• Space‑efficient design: One rank smaller case than LGU in the LGN family helps reduce enclosure and board footprint while maintaining similar performance attributes.
• Wide operating temperature range: −40°C to +105°C operation covers a broad set of deployment environments for general‑purpose electronics.
• Regulatory conformity: RoHS compliance streamlines use in designs that require restricted‑substance conformance.
