LGX2D122MELB40

The LGX2D122MELB40 is an aluminum electrolytic capacitor in a snap‑in terminal radial can designed for high‑temperature, long‑life power applications. It delivers 1.2 mF capacitance at a 200 V rating and is part of Nichicon’s LGX series optimized for inverter and power supply rectifier circuits.

Engineered for sustained ripple handling and extended endurance, this RoHS‑compliant component is intended for designers requiring reliable bulk filtering and smoothing in industrial and power electronics environments.

Key Features

• High‑temperature long life — Rated for operation up to 105°C with endurance of 5000 hours under DC bias plus rated ripple current at 105°C.
• Capacitance and voltage — 1.2 mF nominal capacitance with a 200 V rated voltage and capacitance tolerance of −20% to +20% (measured at 120 Hz, 20°C).
• Ripple current capability — Specified ripple current of 2.53 A at 120 Hz and 3.795 A at 50 kHz for effective smoothing in high‑ripple environments.
• Operating temperature range — Designed for −25°C to +105°C operation to support elevated‑temperature power designs.
• Snap‑in radial can package — Snap‑in terminal mounting for secure PCB retention; physical size listed as L: 4 × D: 3 cm for compact installation.
• Polarized construction — Standard polarized aluminum electrolytic suitable for DC filtering and energy storage roles.
• RoHS compliant — Conforms to RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• General inverters (rectifier circuits) — Bulk smoothing and filtering on inverter rectifier stages where elevated temperature endurance and ripple handling are required.
• Switching power supplies — DC bulk capacitance and ripple absorption for SMPS input/output stages operating at high ripple and elevated temperatures.
• Industrial power electronics — Energy storage and decoupling in industrial drives and converters that demand long life under continuous ripple stress.

Unique Advantages

• Long life under rated ripple — Endurance testing of 5000 hours at 105°C ensures predictable performance in sustained high‑temperature, high‑ripple applications.
• Measured ripple performance — Provided ripple current ratings at both 120 Hz and 50 kHz let designers size bulk capacitance precisely for low‑ and high‑frequency environments.
• Compact snap‑in form factor — Radial snap‑in can with L: 4 × D: 3 cm dimensions enables secure PCB mounting while minimizing board footprint.
• Wide operating temperature window — −25°C to +105°C rating supports a range of industrial ambient conditions without derating design intent.
• Proven series pedigree — Part of Nichicon’s LGX long‑life assurance family, targeted at power supply and inverter applications.
• Regulatory compliance — RoHS conformity reduces material compliance risk for commercial and industrial products.
