LGR2G221MELB40

The LGR2G221MELB40 is a 220 µF, 400 V aluminum electrolytic capacitor from Nichicon’s LGR long‑life snap‑in series. It is a snap‑in terminal, radial can type designed for general‑purpose power applications requiring high voltage capability and extended endurance.

Key value comes from its long‑life assurance at elevated temperature and its capability to handle ripple current across a wide frequency range, making it suitable for demanding industrial and power electronics designs that require stable bulk capacitance and durability.

Key Features

• Capacitance and Voltage — 220 µF nominal capacitance rated at 400 V DC with ±20% tolerance.
• Long‑life Endurance — Rated for 10,000 hours of operation at 105°C under DC bias plus rated ripple current as specified for the LGR series.
• Ripple Current Performance — Rated ripple current of 1.0 A at 120 Hz and 1.43 A at 50 kHz; frequency coefficient for 400/450 V parts is 1.00 at 120 Hz and 1.43 at 50 kHz or more.
• Temperature Range — Operates across –25°C to +105°C for 400 V rated parts.
• Leakage Current — Specified by the LGR series as I ≤ 3√(C·V) µA after 5 minutes’ application of rated voltage at 20°C.
• Package & Mounting — Radial, can type with snap‑in terminals for secure PCB mounting and mechanical retention.
• Environmental Compliance — RoHS compliant (2011/65/EU, (EU)2015/863).

Typical Applications

• Industrial Power Supplies — Bulk energy storage and smoothing in higher‑voltage DC power rails where 400 V ratings and long life at 105°C are required.
• Elevated‑Temperature Environments — Systems that demand sustained performance at up to 105°C and long endurance under ripple stress.
• General Purpose Power Electronics — Filtering and decoupling in general‑purpose equipment that uses snap‑in mounting for robust PCB attachment.

Unique Advantages

• Extended High‑Temperature Durability: 10,000‑hour endurance at 105°C provides predictable aging characteristics for long service life.
• High Voltage Capability: 400 V rating supports higher DC bus designs without requiring parallel components for voltage margin.
• Frequency‑Aware Ripple Handling: Documented ripple current ratings and frequency coefficients (1.00 at 120 Hz, 1.43 at 50 kHz) allow designers to size capacitors with frequency dependence in mind.
• Robust Mechanical Mounting: Snap‑in radial can simplifies assembly and provides secure retention for applications with vibration or mechanical stress.
• Measured Leakage Specification: Leakage current defined by I ≤ 3√(C·V) µA ensures predictable insulation behavior after initial application of rated voltage.
• Regulatory Compliance: RoHS conformity supports use in regions requiring restricted substance compliance.
