LGJ2E181MELZ20

The LGJ2E181MELZ20 is an aluminum electrolytic capacitor from Nichicon's LGJ series, configured as a snap-in terminal radial can in a low-profile package. It provides 180 µF capacitance at a 250 V rating with polarized construction and ±20% tolerance, designed for general-purpose electronic applications.

With an operating temperature range from –40°C to +105°C and a specified lifetime of 3000 hours at 105°C, this component is targeted at designs that require high-temperature endurance in a compact snap-in form factor.

Key Features

• Capacitance & Voltage — 180 µF nominal capacitance with a 250 V rated voltage and polarization, suitable where a mid-range capacitance at high voltage is required.
• Temperature & Lifetime — Rated for –40°C to +105°C operation and specified for 3000 hours at 105°C, supporting sustained high-temperature use.
• Package & Mounting — Radial, can-type snap-in package for fast, secure chassis or board mounting with snap-in terminals.
• Low-Profile Dimensions — Compact footprint with diameter 22 mm and length 20 mm (L: 2.0 cm × D: 2.2 cm) and a seated height maximum of 2.0 cm for space-conscious designs.
• Ripple Performance — Rated ripple current of 750 mA at 120 Hz and 1.125 A at 50 kHz, enabling handling of AC voltage components across typical power frequencies.
• Tolerance & Leakage — Capacitance tolerance of –20% to +20% and leakage current specified per datasheet formula, enabling predictable sizing and screening in designs.

Typical Applications

• General-purpose electronic equipment — Suited to designs that call for a 180 µF, 250 V polarized aluminum electrolytic capacitor in a snap-in radial can.
• High-temperature environments — Applications that require operation up to +105°C with a documented 3000 h lifetime at that temperature.
• Space-constrained assemblies — Low-profile 22 × 20 mm can dimensions and snap-in mounting make it appropriate where board or chassis space is limited.

Unique Advantages

• Compact, low-profile form — 22 mm × 20 mm can size with 2.0 cm seated height maximizes available space without sacrificing capacitance.
• High-temperature endurance — Rated to +105°C with a specified 3000-hour lifetime at that temperature for robust performance in elevated thermal conditions.
• Snap-in mounting for secure installation — Radial snap-in terminals provide mechanical stability and quick assembly for through-hole applications.
• Frequency-aware ripple handling — Specified ripple currents of 750 mA (120 Hz) and 1.125 A (50 kHz) support AC ripple across common power system frequencies.
• Clear electrical characterization — Polarized construction, ±20% tolerance, and manufacturer datasheet guidance simplify component selection and reliability planning.
• Nichicon LGJ series pedigree — Part of the LGJ series, providing consistent form-factor and performance details for designers using series-matched components.
