LGN2E821MELA45

The LGN2E821MELA45 is a snap‑in terminal aluminum electrolytic capacitor designed for general‑purpose industrial and commercial equipment. It provides 820 µF capacitance at a 250 V rating in a compact radial can snap‑in package, offering a combination of high ripple handling and extended high‑temperature endurance.

This part is built for sustained operation up to 105°C and is rated to withstand 3000 hours of applied rated ripple current at 105°C, making it suitable for designs that require reliable bulk capacitance and ripple performance in elevated temperatures. The LGN series also offers a one‑rank smaller case size than the LGU series for space‑sensitive designs.

Key Features

• Capacitance & Voltage — 820 µF capacitance at a 250 V rated voltage provides substantial bulk energy storage for 250 V systems.
• High‑Temperature Endurance — Guaranteed performance across an operating temperature range of −40 °C to +105 °C and endurance of 3000 hours at 105 °C under rated ripple conditions.
• Ripple Current Capability — Rated ripple current of 2 A at 120 Hz and 3 A at 100 kHz, supporting both low‑ and high‑frequency ripple environments.
• Package & Mounting — Radial, snap‑in can package (snap‑in terminal type) for secure chassis or PCB mounting; nominal size L: 4.5 × D: 2.5 cm with a maximum seated height of 1.772 inch.
• Tolerance & Polarity — Capacitance tolerance of −20% to +20% and polarized construction; suitable for polarized bulk and smoothing applications.
• Stability & Loss — Meets tan δ specification (max. 0.15 at 120 Hz for rated voltages in the 160–420 V range) and low‑temperature impedance stability defined in the LGN series specifications.
• Environmental Compliance — Compliant with RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• General‑purpose power filtering — Bulk smoothing and ripple attenuation in 250 V power systems where sustained ripple handling and capacitance are required.
• High‑temperature equipment — Designs that operate at elevated ambient temperatures up to 105 °C and require long‑term endurance under applied ripple current.
• Chassis or PCB snap‑in mounting — Systems that benefit from a snap‑in radial can for secure mechanical mounting and compact board/standoff arrangements.

Unique Advantages

• Extended high‑temperature life: Rated for 3000 hours at 105 °C under rated ripple, enabling reliable performance in prolonged elevated‑temperature duty cycles.
• Dual‑frequency ripple capability: Specified ripple currents at both 120 Hz and 100 kHz support designs with mixed frequency ripple sources.
• Space‑efficient form factor: One rank smaller case size than the LGU series helps reduce enclosure and board footprint while retaining bulk capacitance.
• Clear performance specifications: Defined tan δ and impedance stability values at 120 Hz and low temperatures provide predictable electrical behavior for design validation.
• RoHS compliant: Meets current RoHS requirements for materials compliance in commercial and industrial products.
