LAR2D681MELZ40

The LAR2D681MELZ40 is a snap-in terminal aluminum electrolytic capacitor offering 680 µF capacitance at a 200 V rating in a radial, snap-in can. It is a polarized, general-purpose capacitor designed for applications that require high-voltage bulk capacitance in a compact snap-in package.

Key value propositions include high-temperature endurance (2000 hours at 105°C), robust ripple-current capability across low and high frequencies, and RoHS compliance—making it suitable for production environments that require reliable long-term performance.

Key Features

• Capacitance & Voltage: 680 µF nominal capacitance with a 200 V rated voltage and ±20% tolerance, providing significant bulk energy storage for high-voltage circuits.
• Snap‑in Radial Package: Radial, can-type snap-in mounting for secure mechanical retention in panel or chassis-mounted power assemblies; dimensions approximately 22 mm diameter × 40 mm length.
• High-Temperature Endurance: Rated for operation from −40°C to +105°C with an endurance of 2000 hours at 105°C when subjected to rated ripple current.
• Ripple Current Performance: 1.75 A at 120 Hz (low frequency) and 2.625 A at 50 kHz (high frequency), supporting sustained AC ripple handling across a range of frequencies.
• Low Losses: Maximum tan δ of 0.15 at measurement conditions, indicating controlled dissipation for stable operation.
• Leakage Current: Specified leakage current of 1100 µA after application of rated voltage, consistent with the product’s general-purpose class.
• Safety and Overvoltage Behavior: Designed to reduce short incidence under overvoltage conditions (rated voltage × 1.5) and withstand rated ripple current for extended endurance testing.
• Compliance & Production: RoHS compliant, supplied in tray packing, and available in mass production quantities for manufacturing continuity.

Typical Applications

• General Purpose — High‑voltage bulk capacitance: Provides 680 µF at 200 V for general-purpose circuits requiring energy storage and voltage support in a snap-in format.
• General Purpose — High-temperature environments: Suitable for designs that require continuous operation up to 105°C with 2000 hours of rated ripple-current endurance.
• General Purpose — Production assemblies: Tray-packed snap-in package simplifies handling and installation for mass-production assemblies requiring RoHS-compliant components.

Unique Advantages

• Extended high-temperature endurance: 2000 hours at 105°C supports long-term reliability in elevated-temperature installations.
• Robust ripple handling across frequencies: Rated ripple currents of 1.75 A (120 Hz) and 2.625 A (50 kHz) deliver dependable AC performance for diverse operating conditions.
• Snap-in mounting for secure installation: Radial snap-in can provides mechanical stability for chassis or panel-mounted power modules.
• Controlled dissipation: tan δ max 0.15 helps limit internal heating and supports predictable performance under load.
• Overvoltage mitigation: Designed to reduce short incidence when exposed to 1.5× rated voltage, improving fault tolerance during abnormal voltage events.
• Production-ready supply: RoHS compliance and tray packing support regulatory and manufacturing requirements for volume production.
