LAR2D102MELZ50

The LAR2D102MELZ50 is a Nichicon aluminum electrolytic capacitor in a snap-in terminal (radial, can – snap-in) package, offering 1000 µF capacitance at a 200 V rating. Designed as a general-purpose component, it targets applications that require bulk capacitance with high-temperature endurance and robust ripple handling.

Key value comes from its 105°C permissible overvoltage design, a 2000-hour rated ripple-current endurance at 105°C, and construction that reduces short incidence under overvoltage conditions (rated voltage × 1.5).

Key Features

• Capacitance and Voltage — 1000 µF nominal capacitance with a 200 V rated voltage and ±20% capacitance tolerance.
• High-temperature endurance — Rated for operation from −40°C to +105°C and specified to withstand 2000 hours of rated ripple current at 105°C.
• Permissible overvoltage design — Constructed to reduce short incidence when 1.5× rated voltage is applied, improving safety under transient overvoltage conditions.
• Ripple current capability — Specified ripple current: 2.3 A at 120 Hz and 3.45 A at 50 kHz, with frequency coefficients detailed for other frequencies.
• Package and mounting — Snap-in terminal, radial can package for secure board mounting and mechanical stability.
• Polarized design — Polarized aluminum electrolytic construction for DC bulk energy storage applications.
• Environmental compliance — RoHS compliant (2011/65/EU, (EU)2015/863).
• Physical dimensions — Size: length 5.0 cm × diameter 2.2 cm; maximum seated height 1.969 inch.

Typical Applications

• General-purpose power circuits — Provides bulk capacitance where 1000 µF at 200 V is required, with rated ripple endurance at elevated temperatures.
• High-temperature systems — Suited to applications that operate up to 105°C and require components that sustain performance under thermal stress.
• High-ripple environments — Appropriate for circuits that demand sustained ripple handling, supported by specified ripple current ratings at 120 Hz and 50 kHz.

Unique Advantages

• Long-duration ripple endurance: Specified to withstand 2000 hours of rated ripple current at 105°C, enabling predictable lifetime behavior in high-stress thermal/ripple conditions.
• Overvoltage safety considerations: Designed to reduce short incidence when subjected to 1.5× rated voltage, offering an added level of operational robustness during overvoltage events.
• High ripple capacity across frequencies: Clear ripple current specifications (2.3 A at 120 Hz, 3.45 A at 50 kHz) and frequency coefficients allow designers to assess performance across common switching and line frequencies.
• Secure snap-in mounting: Radial snap-in can package provides reliable mechanical retention for board-level power assemblies.
• Regulatory compliance: RoHS conformity supports environmental requirements in regulated product lines.
