LGN2X121MELB45

The LGN2X121MELB45 is a snap-in terminal aluminum electrolytic capacitor designed for general-purpose high-voltage applications. It combines a 120 µF capacitance with a 600 V rating in a smaller-sized radial can package, delivering reliable filtering and energy-handling capability where elevated operating temperature and ripple tolerance are required.

Engineered for robust operation up to 105°C and compliant with RoHS (2011/65/EU, (EU)2015/863), this part is intended for designs that need compact, high-voltage electrolytic capacitance with predictable lifetime and ripple performance.

Key Features

• Core Type – Aluminum Electrolytic, Snap-In Terminal Radial can with snap-in terminals for secure PCB mounting; polarized design for DC applications.
• Capacitance & Voltage 120 µF nominal capacitance with a 600 V rated voltage and tolerance of ±20%.
• Temperature Range & Endurance Operating temperature range of –25°C to +105°C. Endurance specified as 2000 hours at 105°C for parts rated at 600 V when subjected to D.C. bias plus rated ripple current.
• Ripple Current Handling Rated ripple current of 740 mA at 120 Hz and 1.058 A at 100 kHz, supporting sustained AC stress under rated conditions.
• Electrical Stability For 450–600 V parts, tangent of loss angle (tan δ) is specified with a maximum of 0.20; low-temperature impedance ratio Z(–25°C)/Z(+20°C) is specified up to 8 for 350–600 V parts.
• Compact Package & Form Factor One rank smaller case size than the LGU series, with dimensions L: 4.5 × D: 3 cm and a snap-in radial can package for space-conscious power boards.
• Regulatory Compliance RoHS compliant (2011/65/EU, (EU)2015/863).

Typical Applications

• Power supply filtering — Provides high-voltage capacitance for smoothing and decoupling in DC power supplies and high-voltage rails.
• Industrial power electronics — Suitable for general-purpose industrial equipment that requires stable performance up to 105°C and sustained ripple handling.
