LAR2D182MELB50

The LAR2D182MELB50 is a snap-in terminal aluminum electrolytic capacitor offering 1800 µF capacitance at a 200 V rating. Designed for general-purpose power applications, it delivers high bulk capacitance, strong ripple-handling capability, and long-term endurance for demanding industrial and commercial designs.

With a −40°C to +105°C operating range, snap-in can packaging, and tray packing for mass production, this capacitor is engineered to simplify assembly while meeting elevated temperature ripple and lifetime requirements.

Key Features

• Capacitance & Tolerance — 1.8 mF (1800 µF) nominal capacitance with ±20% tolerance at 120 Hz, 20°C for predictable energy storage and filtering.
• High Voltage Rating — Rated at 200 V to support higher-voltage power rails and bulk decoupling across industrial power supplies.
• Ripple Current Performance — Low-frequency ripple current 3.08 A at 120 Hz and high-frequency ripple current 4.62 A at 50 kHz, enabling effective handling of both low- and high-frequency ripple components.
• Temperature and Endurance — Operates from −40°C to +105°C with a rated lifetime of 2000 hours at 105°C under rated ripple, supporting sustained high-temperature operation.
• Loss Characteristics — Tangent of loss angle (tanδ) specified at 0.15 (max.) for the 200 V range, providing defined dissipation characteristics.
• Leakage Current — Initial leakage current specified at 1800 µA to help estimate quiescent losses in power systems.
• Mechanical & Packaging — Snap-in radial can (φ30×50 mm) for secure board mounting and tray packing suitable for mass-production workflows.
• Safety & Overvoltage Design — Series design reduces short incidence under overvoltage and meets a safety performance criterion where more than 60% of parts pass a 1.5× rated voltage test (limited current = 1 A).
• Environmental Compliance — RoHS compliant to support regulatory requirements.

Typical Applications

• Power filtering and bulk energy storage — Provides large-capacitance bulk decoupling on 200 V rails for smoothing and energy reservoir functions.
• Industrial power supplies — High ripple-current capability and 105°C endurance make it suitable for sustained operation in industrial power systems.
• Commercial electronic equipment — Snap-in can packaging and tray packing facilitate assembly in high-volume production environments.

Unique Advantages

• Large capacitance in a compact snap-in package: 1800 µF in a φ30×50 mm can provides significant bulk capacitance while enabling secure board mounting.
• Designed for high ripple environments: Specified ripple currents at both low and high frequencies (3.08 A @120 Hz, 4.62 A @50 kHz) support mixed-frequency power systems.
• High-temperature endurance: 2000 hours at 105°C under rated ripple ensures predictable lifetime in elevated-temperature applications.
• Controlled dissipation and leakage: tanδ max 0.15 and defined leakage current (1800 µA) help engineers model thermal and standby behavior accurately.
• Overvoltage safety consideration: Series design reduces short incidence under 1.5× rated-voltage conditions and meets the datasheet safety performance criteria.
• Production-ready packaging: Tray packing supports automated assembly and inventory handling for mass-production programs.
