LAR2E331MELZ30

The LAR2E331MELZ30 is a polarized aluminum electrolytic capacitor in a snap-in terminal, radial can package. It delivers 330 µF capacitance at a 250 V rating with a compact 22 mm diameter and 30 mm length profile.

Designed for general-purpose electronic designs, this part combines elevated-temperature endurance, measurable ripple-current capability, and built-in safety behavior under overvoltage conditions to support reliable power assemblies and board-mounted power modules.

Key Features

• Capacitance & Voltage: 330 µF capacitance rated at 250 V for bulk energy storage and decoupling in polarized circuits.
• Snap-in Radial Can Package: Snap-in terminal mounting for secure board installation; package dimensions L: 30 mm × D: 22 mm aid compact power-module integration.
• High-Temperature Endurance: Withstands 2000 hours of rated ripple current at 105 °C, enabling extended operation in elevated-temperature environments.
• Ripple Current Ratings: 1.2 A at 120 Hz and 1.8 A at 50 kHz frequency points, with series frequency coefficients provided for other frequencies.
• Overvoltage Safety Behavior: Series-level reduction of short incidence when subjected to overvoltage (rated voltage × 1.5) and defined safety performance under limited-current overvoltage testing.
• Electrical Characteristics: Capacitance tolerance ±20%; leakage current defined by I ≤ 3√CV (µA) after 5 minutes at 20 °C; tan δ specified for rated voltages at 120 Hz.
• Environmental Compliance: Compliant with RoHS directives (2011/65/EU, (EU)2015/863).

Typical Applications

• General-purpose electronics: Use where a polarized 250 V, 330 µF snap-in capacitor is required for board-mounted power components and assemblies.
• Power supply modules: Suitable for power modules and assemblies that need snap-in, high-voltage bulk capacitance with defined ripple-current endurance up to 105 °C.
• Industrial equipment: Applicable to general-purpose industrial circuits requiring long-term stability at elevated ambient temperatures.

Unique Advantages

• Extended endurance at 105 °C: 2000 hours of rated ripple-current application supports longer service intervals in hot environments.
• Measurable ripple capability: Specified ripple currents (1.2 A at 120 Hz, 1.8 A at 50 kHz) and frequency coefficients allow designers to size capacitors against real operating conditions.
• Improved safety under overvoltage: Series-level measures reduce the incidence of shorts when exposed to 1.5× rated voltage, providing predictable behavior in fault scenarios.
• Compact snap-in form factor: Radial, snap-in can (22 mm × 30 mm) delivers high-capacitance density in a PCB-friendly mounting style.
• Regulatory compliance: RoHS compliance simplifies use in equipment that must meet restricted-substances requirements.
