LAR2G181MELZ35

The LAR2G181MELZ35 is a snap-in terminal aluminum electrolytic capacitor specified at 400 V and 180 µF. Designed as a radial can, snap-in package for general-purpose applications, it delivers high-voltage bulk capacitance with polarized construction.

Key performance attributes include endurance under elevated temperature and ripple conditions (2000 hours at 105°C with rated ripple current), reduced short incidence under overvoltage conditions, and RoHS compliance for environmental compatibility.

Key Features

• High-voltage bulk capacitance — 180 µF rated capacitance at 400 V provides substantial energy storage for high-voltage circuits.
• Snap-in terminal, radial can package — φ22 × 35 mm (3.5 × 2.2 cm) can with snap-in mounting for secure chassis or board-mounted installations.
• High-temperature endurance — Specified to withstand 2000 hours of rated ripple current at 105°C, supporting sustained operation at elevated temperatures.
• Overvoltage safety performance — Reduced incidence of shorting when exposed to 1.5× rated voltage; datasheet shows passing behavior under rated overvoltage with limited current.
• Polarized design — Intended for DC circuits requiring polarized electrolytic capacitance.
• Measured ripple capability — Rated ripple currents: 950 mA at 120 Hz and 1.359 A at 50 kHz (product-specific values).
• RoHS compliant — Meets RoHS directive (2011/65/EU, (EU)2015/863) requirements.

Typical Applications

• General-purpose power circuits — Provides high-voltage energy storage and smoothing for general-purpose DC power sections requiring 400 V rated capacitance.
• Chassis or cabinet-mounted power assemblies — Snap-in radial can package suits secure mounting in power modules and assemblies where robust mechanical fixation is needed.
• High-temperature environments — Endurance rating at 105°C supports use in applications with sustained elevated operating temperatures.

Unique Advantages

• Long ripple endurance: 2000-hour rating at 105°C under rated ripple current reduces maintenance and replacement cycles in demanding thermal conditions.
• High-voltage capability: 400 V rating enables use in higher-voltage DC circuits without series stacking of components.
• Snap-in mounting for reliable installation: Radial, snap-in can design provides a secure mechanical and electrical connection for board or chassis integration.
• Overvoltage safety behavior: Design reduces short incidence under 1.5× rated voltage conditions, supporting safer fault tolerance in overvoltage events.
• Measured ripple performance: Published ripple current values at 120 Hz and 50 kHz allow designers to size components confidently for frequency-specific ripple requirements.
• Regulatory compliance: RoHS conformity supports deployment in regions with restricted substances regulations.
