LGU2E821MELC

The LGU2E821MELC is a snap‑in terminal aluminum electrolytic capacitor designed for general‑purpose electronic applications requiring high voltage and elevated temperature endurance. With a rated voltage of 250 V and 820 µF capacitance, this radial can-type capacitor delivers robust smoothing and bulk energy support in systems that demand long life and stable performance.

Engineered for continuous operation up to 105°C and produced for mass volumes with tray packing, the LGU2E821MELC combines high ripple tolerance and controlled dissipation factor for reliable performance in demanding power environments.

Key Features

• Capacitance & Voltage — 820 µF nominal capacitance at a rated voltage of 250 V with ±20% tolerance for predictable bulk energy storage.
• Snap‑In Radial Package — Can‑type, snap‑in terminal construction (φ35 × 35L) for secure board mounting and simplified assembly; packed in trays for production handling.
• High Temperature Endurance — Rated for operation from −40°C to 105°C with a specified endurance of 3000 hours at 105°C under rated ripple current.
• Low Dissipation Factor — Tangent of loss angle (tan δ) of 0.15 (max.) measured at 20°C, 120 Hz for controlled losses and thermal behavior.
• Ripple Current Capability — Supports 2.3 A at 120 Hz (low frequency) and 3.45 A at 50 kHz (high frequency), enabling effective filtering across a wide frequency range.
• Leakage Performance — Specified leakage current of 1,350 µA (after rated voltage applied for the defined test interval), supporting predictable bias behavior.
• RoHS Compliant — Meets RoHS directive requirements for restricted substances.

Typical Applications

• General Purpose Electronics — Bulk capacitance and smoothing in general‑purpose circuits where 250 V operation and 820 µF capacity are required.
• Industrial Power Supplies — Bulk energy storage and ripple suppression in power conversion systems operating up to 105°C.
• Power Conversion & Filtering — Suitable for designs that require high ripple current handling at both low and high frequencies (2.3 A at 120 Hz; 3.45 A at 50 kHz).
• High‑Temperature Environments — Applications that require sustained operation and 3000‑hour endurance at elevated temperature (105°C).

Unique Advantages

• High Voltage Capability: 250 V rating supports higher‑voltage power systems without additional series components.
• Long Endurance at Elevated Temperature: 3000 hours at 105°C provides predictable life for designs exposed to sustained thermal stress.
• Wide Frequency Ripple Handling: Separate ripple current specifications for low and high frequency (2.3 A @120 Hz, 3.45 A @50 kHz) enable effective suppression across switching and line frequencies.
• Controlled Losses: tan δ = 0.15 (max.) at 20°C, 120 Hz supports thermal stability and efficient operation in continuous duty.
• Production‑Ready Packaging: Tray packing and mass production availability simplify procurement and assembly for volume builds.
• Regulatory Compliance: RoHS compliance reduces materials risk and eases integration into regulated product lines.
