Engineered for sustained operation at elevated temperatures, this Nichicon LAR series part offers long endurance at 105°C and ripple handling suited to both low and high frequency power circuits, making it appropriate for industrial and commercial electronic equipment.

Key Features

• Capacitance & Voltage — 820 µF nominal capacitance with a 200 V rated voltage and ±20% tolerance, providing substantial bulk energy storage for power filtering and smoothing.
• High‑Temperature Endurance — Rated for 2000 hours at 105°C, enabling reliable performance in high‑temperature operating environments.
• Ripple Current Capability — Low‑frequency ripple current of 2.04 A at 120 Hz and high‑frequency ripple current of 3.06 A at 50 kHz to support AC ripple in power conversion and regulation circuits.
• Low Loss — Specified tan δ of 0.15 (max) at 120 Hz, 20°C, for predictable dissipation characteristics in AC conditions.
• Leakage Current — Typical leakage current specified at 1.21 mA, consistent with application requirements after voltage application.
• Robust Package & Mounting — Snap‑in radial can (φ22 × 45 mm) for secure mechanical retention in power modules and assemblies.
• Wide Operating Temperature — Rated from −40°C to +105°C to cover a broad range of industrial environments.
• Safety Performance Under Overvoltage (Series Characteristic) — LAR series design reduces incidence of shorts when subjected to 1.5× rated voltage and includes pressure relief behavior as part of its safety performance metrics.
• RoHS Compliant — Conforms to RoHS directive requirements for environmental compliance.

Typical Applications

• Power Supply Filtering — Bulk capacitance for smoothing and decoupling in 200 V power rails and high‑voltage switch‑mode supplies.
• Industrial Power Modules — Energy storage and ripple suppression in industrial converters and control equipment operating at elevated temperatures.
• Commercial Electronics — General‑purpose filtering and energy buffering in commercial power systems and electronic assemblies.

Unique Advantages

• Long High‑Temperature Life: 2000 hours at 105°C provides predictable aging characteristics for designs exposed to sustained heat.
• High Voltage Handling: 200 V rating supports higher‑voltage power architectures while delivering large capacitance.
