LAR2D681MELA30

The LAR2D681MELA30 is a Nichicon LAR series aluminum electrolytic capacitor in a snap‑in terminal can designed for general‑purpose power applications. It delivers 680 µF at 200 V with snap‑in mounting, engineered for extended operation up to 105°C.

Its key value lies in durable high‑temperature endurance and robust ripple handling, making it suited for production environments that require reliable bulk capacitance in radial, snap‑in packaging with tray packing for mass production.

Key Features

• Electrical Performance — 680 µF nominal capacitance at 200 V rated voltage with ±20% tolerance and a maximum tanδ of 0.15 (measured at 120 Hz, 20°C).
• High Ripple Capability — Rated ripple current of 1.75 A at 120 Hz (low frequency) and 2.625 A at 50 kHz (high frequency), supporting significant AC stress handling in power circuits.
• High‑Temperature Endurance — Specified for 2000 hours at 105°C with DC bias plus rated ripple current, meeting defined endurance criteria for capacitance change, tanδ increase, and leakage current.
• Leakage Current — Low leakage current rated at 1100 µA, measured after specified voltage application conditions.
• Mechanical & Mounting — Snap‑in terminal, radial can package (φ25 × 30 mm length) designed for secure chassis or PCB mounting and simplified assembly; supplied in tray packing for production handling.
• Safety & Overvoltage Behavior — Series design includes measures to reduce short incidence under overvoltage conditions (rated voltage × 1.5) and meets defined safety performance criteria under limited overvoltage testing.
• Compliance — RoHS compliant.

Typical Applications

• General‑purpose power systems — Bulk capacitance and ripple support where 680 µF at 200 V is required for general‑purpose power circuits.
• Industrial equipment — Deployment in production and industrial environments that require elevated temperature endurance up to 105°C and tray packing for assembly lines.
• Power filtering and smoothing — Handles DC bias with rated ripple current over long durations to stabilize DC rails in general applications.

Unique Advantages

• Proven high‑temperature endurance: 2000 hours at 105°C under DC bias plus rated ripple current provides predictable lifespan metrics for thermal stress conditions.
• Clear ripple specifications: Published ripple current ratings at both low‑ and high‑frequency (1.75 A at 120 Hz; 2.625 A at 50 kHz) let engineers size capacitors against real circuit ripple loads.
• Snap‑in packaging for robust mounting: Radial can with snap‑in terminals simplifies mechanical retention and assembly in production environments.
• Manufacturing ready: Tray packing and mass production availability support high‑volume assembly workflows.
• Measured loss and leakage limits: Specified tanδ (0.15 max) and leakage current ratings enable predictable AC and DC behavior for circuit design margins.
• RoHS compliant: Meets RoHS requirements for regulatory and environmental compliance in applicable markets.
