LGN2P122MELB40

The LGN2P122MELB40 is a polarized aluminum electrolytic capacitor in a snap‑in terminal package, designed for general-purpose power applications that require compact, high‑temperature performance. It delivers 1.2 mF capacitance at a 220 V rating and is built to withstand extended ripple current stress at elevated temperature.

As a member of Nichicon’s LGN series, this part inherits the series’ 105°C endurance design and one‑rank smaller case sizing compared with LGU, while remaining RoHS compliant.

Key Features

• Capacitance and Voltage — 1.2 mF capacitance rated at 220 V for energy storage and bulk filtering in power circuits.
• High‑temperature Endurance — Specified operating range −40°C to 105°C with a rated endurance of 3000 hours at 105°C under rated ripple current.
• Rated Ripple Current — Handles 2.5 A at 120 Hz (low frequency) and 3.75 A at 100 kHz (high frequency), supporting demanding ripple environments.
• Compact Snap‑in Package — Snap‑in, radial can mounting for robust PCB retention and secure mechanical connection; overall size approximately L: 4 × D: 3 cm.
• Tight Manufacturing Tolerance — Capacitance tolerance of −20% to +20% for predictable design behavior.
• Polarized Design — Polar capacitor for DC bulk filtering and smoothing applications.
• Regulatory Compliance — Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• General‑purpose power filtering — Bulk smoothing and ripple reduction in power supplies and DC link circuits where high ripple endurance is required.
• Industrial electronics — Energy storage and filtering in industrial control equipment that operates across a wide temperature range.
• Power conversion modules — DC filtering in inverters, converters, and other power conversion stages where snap‑in mounting and high ripple capability are beneficial.

Unique Advantages

• Extended ripple endurance: Rated to withstand 3000 hours of rated ripple current at 105°C, enabling longer operational life under thermal and electrical stress.
• High ripple current capability: Specified ripple currents of 2.5 A (120 Hz) and 3.75 A (100 kHz) support both low‑ and high‑frequency switching environments.
• Space‑efficient packaging: One rank smaller case size than LGU provides a lower footprint option within the LGN series for space‑constrained designs.
• Secure PCB mounting: Snap‑in radial can construction offers robust mechanical retention for board‑level assemblies.
• Wide operating temperature range: −40°C to 105°C supports applications across varied environmental conditions.
• RoHS compliance: Conforms to modern environmental requirements for electronics assemblies.
