LGN2E821MELB35

The LGN2E821MELB35 is an aluminum electrolytic, snap‑in terminal capacitor designed for general-purpose power applications. It combines a 820 µF capacitance with a 250 V rating and a compact, snap‑in radial can package to deliver high ripple endurance and reliable performance in elevated-temperature environments.

Engineered for sustained operation up to 105°C with 3000 hours of rated ripple-current endurance, this part is suited to designs that require robust bulk energy storage and stable filtering in a smaller case size relative to the LGU series. The component is RoHS compliant.

Key Features

• Capacitance & tolerance — 820 µF nominal with ±20% tolerance at 120 Hz, 20°C, providing predictable bulk capacitance for power filtering and energy buffering.
• Voltage rating — 250 V rated voltage for medium-voltage power applications that require higher DC withstand capability.
• High-temperature endurance — Rated for operation to 105°C with a specified endurance test of 3000 hours at 105°C under DC bias plus rated ripple current; after the test, capacitance change remains within ±20% and leakage/tan δ remain within specified limits.
• Ripple current capability — Designed to withstand rated ripple currents of 2 A at 120 Hz and 3 A at 100 kHz, supporting sustained AC ripple handling in switching and power-conversion environments.
• Package and mounting — Snap‑in, radial can package for secure board mounting and straightforward assembly in power assemblies.
• Operating temperature range — –40°C to +105°C (applicable for the 250 V rating), allowing use across a broad industrial temperature span.
• Polarized design — Polar construction for use where marked polarity is required.
• Compact size — One rank smaller case than the LGU series; physical size approximately L: 3.5 × D: 3 cm, enabling space savings on populated power boards.
• RoHS compliant — Conforms to RoHS directive (2011/65/EU, (EU)2015/863) for lead-free designs.

Typical Applications

• Power supply filtering — Bulk smoothing and output filtering in medium-voltage power supplies where 250 V rating and high ripple endurance are required.
• Power conversion — Energy buffering in DC‑DC converters and switching circuits that demand sustained ripple current capability at elevated temperatures.
• Industrial equipment — General-purpose bulk capacitance for industrial control and power electronics operating up to 105°C.

Unique Advantages

• Space-efficient form factor: One rank smaller case than LGU and compact dimensions (L: 3.5 × D: 3 cm) reduce board footprint without sacrificing capacitance.
• High-temperature reliability: Endurance proven for 3000 hours at 105°C under rated ripple and DC bias, delivering predictable performance in hot operating environments.
• Measured ripple capability: Specified ripple current ratings of 2 A (120 Hz) and 3 A (100 kHz) support demanding switching and high-frequency loads.
• Robust lifecycle characteristics: After endurance and shelf-life tests, capacitance remains within ±20% and leakage/tan δ remain within specified limits, supporting long-term stability.
• Snap‑in mounting: Secure, board‑friendly installation that simplifies assembly for power module and chassis-mounted designs.
• Regulatory readiness: RoHS compliance facilitates integration into lead‑free product portfolios.
