LGN2Z821MELB25

The LGN2Z821MELB25 is an 820 µF, 180 V aluminum electrolytic capacitor in a snap-in radial can designed for general-purpose applications. It combines a compact, smaller-sized case for space-constrained assemblies with a high operating temperature rating and extended ripple-current endurance.

Engineered to withstand demanding thermal and ripple stress, this part delivers 3000 hours of rated ripple-current endurance at 105°C and is RoHS compliant, making it suitable for applications that require sustained performance at elevated temperatures.

Key Features

• Capacitance and Voltage: 820 µF nominal capacitance with a 180 V rated voltage and capacitance tolerance of ±20% (120 Hz, 20°C).
• High-temperature Endurance: Rated for operation from −40°C to 105°C with a specified lifetime of 3000 hours at 105°C under rated ripple current.
• Ripple-current Capability: Rated ripple current of 2 A at 120 Hz and 3 A at 100 kHz, supporting sustained AC stress in power circuits.
• Snap-in Radial Can Package: Snap-in mounting type in a radial, can-style package for secure mechanical retention and simplified assembly.
• Compact Footprint: Smaller-sized case compared with the LGU series, with dimensional footprint approximately L: 2.5 × D: 3.0 cm to help save board and chassis space.
• Environmental Compliance: Compliant with the RoHS directive (2011/65/EU and (EU)2015/863).

Typical Applications

• General-purpose power filtering: Bulk smoothing and decoupling in general-purpose circuits where 820 µF at 180 V and robust ripple handling are required.
• High-temperature equipment: Power assemblies and modules that operate up to 105°C and need capacitors with proven 3000-hour endurance under rated ripple current.
• Snap-in mounted power modules: Chassis or module-mounted power supplies and assemblies that benefit from snap-in radial can mounting for mechanical stability and ease of installation.

Unique Advantages

• Proven thermal endurance: 3000 hours at 105°C under rated ripple current provides measurable reliability for sustained high-temperature operation.
• High ripple capability: Specified ripple currents at both low and high frequencies (2 A @ 120 Hz, 3 A @ 100 kHz) support a range of power-conversion topologies and switching conditions.
• Space-saving form factor: One rank smaller case size versus LGU-series parts enables denser board and module designs without sacrificing capacitance.
• Robust mounting: Snap-in radial can package offers secure retention in power assemblies and simplifies mechanical integration.
• Regulatory compliance: RoHS conformity reduces environmental and supply-chain risk for regulatory-sensitive designs.
