LGG2E821MELC30

The LGG2E821MELC30 is a snap‑in terminal aluminum electrolytic capacitor rated at 820 µF and 250 V, designed for general‑purpose power applications. It belongs to Nichicon's LGG series, offering an ultra‑smaller case size (one rank smaller than LGN) to support equipment downsizing without sacrificing essential performance.

Key attributes include a wide operating temperature range, high ripple handling, and a 2000‑hour endurance at 105°C, making it suitable for compact power supplies and commercial/industrial electronics that require reliable bulk capacitance.

Key Features

• Capacitance & Voltage — 820 µF nominal capacitance with a 250 V rated voltage to provide bulk energy storage and smoothing capability in high‑voltage circuits.
• Snap‑in Terminal Package — Radial, can snap‑in mounting for secure PCB installation and simplified assembly in vertical board layouts.
• Compact, Space‑Saving Size — φ35 × 30 mm overall dimensions and specified as one rank smaller than LGN, enabling smaller power module footprints and equipment downsizing.
• High Temperature Endurance — Rated for operation from −40°C to +105°C with a specified lifetime of 2000 hours at 105°C under rated conditions.
• Ripple Current Capability — Rated ripple current up to 2 A at 120 Hz and 3 A at 100 kHz to support filtering and smoothing under AC ripple conditions.
• Electrical Tolerance & Leakage — Capacitance tolerance −20% to +20% and leakage current specified per datasheet formula (I ≤ 3√CV μA after 5 minutes at 20°C).
• RoHS Compliant — Conforms to RoHS directive (2011/65/EU, (EU)2015/863) for restricted substances compliance.

Typical Applications

• General‑Purpose Power Supplies — Bulk smoothing and filtering in compact AC/DC and DC/DC converters where a 250 V rated capacitor is required.
• Equipment Downsizing — Ideal for designers moving to smaller power module footprints thanks to its reduced case size compared to LGN.
• Commercial and Industrial Electronics — Reliable bulk capacitance for control panels, instrumentation, and other general‑purpose systems operating up to 105°C.

Unique Advantages

• Smaller Form Factor: One rank smaller case than LGN enables reduced enclosure and PCB area without changing capacitor family or performance class.
• High‑Temperature Reliability: 2000 hours endurance at 105°C provides predictable performance for designs that must tolerate elevated operating temperatures.
• Robust Ripple Handling: Defined ripple current ratings (2 A at 120 Hz, 3 A at 100 kHz) support effective ripple suppression in power circuits.
• Secure Snap‑in Mounting: Radial snap‑in can construction simplifies mechanical retention and assembly for vertical board designs.
• Regulatory Compliance: RoHS conformity supports designs targeting global markets with restricted substance requirements.
