LGN2E821MELC30

The LGN2E821MELC30 is a snap-in terminal aluminum electrolytic capacitor designed for general-purpose electronic power applications. It delivers 820 µF nominal capacitance at a rated voltage of 250 V in a compact, radial can snap-in package sized L: 3 × D: 3.5 cm.

Engineered for elevated-temperature operation, the LGN series provides extended endurance at 105°C and is RoHS compliant, making it suitable for designs that require stable capacitance, reliable ripple handling, and long-term thermal performance.

Key Features

• Capacitance & Voltage — 820 µF nominal capacitance with a rated voltage of 250 V for bulk energy storage in general-purpose circuits.
• High-Temperature Endurance — Specified to withstand 3000 hours of rated ripple current at 105°C, supporting sustained operation in hot environments.
• Snap-In Radial Can Package — Snap-in terminal type (radial, can - snap-in) for secure chassis/board mounting and simplified assembly.
• Ripple Current Performance — Rated ripple current capability of 2 A at 120 Hz and 3 A at 100 kHz to support AC ripple filtering and decoupling duties under load.
• Wide Operating Temperature Range — Operates from −40°C to +105°C, enabling use across a broad range of environmental conditions.
• Polarized Electrolytic Construction — Polarized device with capacitance tolerance of −20% to +20% at 120 Hz, 20°C.
• Compact Footprint — One rank smaller case size than LGU series and compact dimensions (L: 3 × D: 3.5 cm) for space-constrained designs.
• Regulatory Compliance — Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• General Purpose Electronics — For general-purpose circuits that require a polarized snap-in aluminum electrolytic capacitor with 820 µF at 250 V and elevated-temperature endurance.
• Industrial Power Modules — Suitable for general-purpose industrial modules operating within −40°C to +105°C and requiring long ripple-endurance at high temperature.
• Chassis-Mounted Power Assemblies — Snap-in terminal and radial can package simplify mounting in power supply and assembly designs where secure mechanical retention is needed.

Unique Advantages

• Proven High-Temperature Life: 3000 hours rated ripple endurance at 105°C provides predictable performance and longevity under thermal stress.
