LGN2P821MELC25

The LGN2P821MELC25 is an 820 µF, 220 V polarized aluminum electrolytic capacitor in a snap-in terminal, smaller-sized can designed for general-purpose electronic equipment. It is built to operate across a wide temperature range and to withstand sustained ripple current at elevated temperature.

Key value propositions include endurance under high-temperature ripple conditions (3000 hours at 105°C), a compact case size (one rank smaller than LGU in the LGN series), and RoHS compliance for regulatory alignment.

Key Features

• Capacitance & Tolerance — 820 µF nominal capacitance with ±20% tolerance at 120 Hz, 20°C, suitable for bulk energy storage and smoothing in general-purpose designs.
• Rated Voltage — 220 V rated voltage to support higher-voltage power applications within the series’ rated voltage range.
• High-Temperature Endurance — Designed to withstand 3000 hours of rated ripple current at 105°C (endurance condition specified for the LGN series).
• Ripple Current Handling — Specified ripple current performance includes 1.93 A at 120 Hz and 2.895 A at 100 kHz, supporting continuous filtering under AC ripple stress.
• Operating Temperature Range — −40°C to +105°C operating range for use across a broad set of environmental conditions.
• Compact Snap-In Package — Snap-in terminal, radial can package with compact dimensions (L: 2.5 × D: 3.5 cm and maximum seated height 2.5 cm) for secure PCB mounting and reduced board footprint relative to larger LGU cases.
• Polarized Construction — Polarized aluminum electrolytic design appropriate for DC applications requiring polarized capacitance.
• RoHS Compliant — Conforms to RoHS directive (2011/65/EU, (EU)2015/863), supporting environmental regulatory requirements.

Typical Applications

• General-purpose electronic equipment — Bulk filtering and energy storage where a 820 µF, 220 V polarized capacitor with high-temperature ripple endurance is required.
• Power supply modules — DC bus smoothing and ripple suppression in power conversion modules that operate up to 105°C.
• Industrial electronics — Use in industrial control and power electronics assemblies that demand reliable high-temperature performance and compact snap-in mounting.

Unique Advantages

• Durable high-temperature performance: Rated for 3000 hours at 105°C under rated ripple current, enabling long-term stability in elevated-temperature environments.
• Compact footprint: One rank smaller case size than LGU in the LGN series, allowing designers to save board space without sacrificing capacitance.
• Clear ripple specifications: Published ripple current figures (1.93 A at 120 Hz and 2.895 A at 100 kHz) make thermal and reliability planning more predictable.
• Snap-in mounting: Robust radial, snap-in can package for secure mechanical retention and straightforward PCB integration.
• Wide operating temperature: −40°C to +105°C rating accommodates a broad range of environmental conditions common to general-purpose and industrial applications.
• Regulatory readiness: RoHS compliance aligns the component with common environmental regulations.
