LGU2P821MELA

The LGU2P821MELA is a Nichicon aluminum electrolytic capacitor in a snap‑in terminal, radial can package designed for general-purpose electronic applications. It delivers 820 µF at 220 V with a wide operating temperature range and specified endurance for elevated-temperature service.

This part is optimized for designs that require high capacitance, rated ripple-current capability, and long life at up to 105°C while maintaining low leakage and a compact φ25 × 50 mm footprint.

Key Features

• Capacitance & Voltage — 820 µF nominal capacitance with a rated voltage of 220 V and ±20% tolerance, suitable for bulk capacitance requirements in general-purpose designs.
• High-temperature Endurance — Rated lifetime of 3000 hours at 105°C when subjected to D.C. bias plus rated ripple current, with defined post-test limits for capacitance, tan δ and leakage current.
• Rated Ripple Current — Supports 2.1 A at 120 Hz (low frequency) and 3.15 A at 50 kHz (high frequency), enabling reliable ripple handling across common frequencies.
• Low Leakage — Specified leakage current of 1270 µA (measured after 5 minutes at 20°C under rated voltage), helping maintain efficiency in long-duration applications.
• Robust Temperature Range — Operating temperature range from −40°C to 105°C, matching the LGU series category specification for 16–250 V parts.
• Snap‑in Radial Can Package — φ25 × 50 mm radial, snap‑in can offers secure PCB mounting and compact volume for chassis- or board-mounted designs.
• RoHS Compliant — Conforms to RoHS directives included in the LGU series documentation.

Typical Applications

• General-purpose electronic systems — Provides bulk capacitance where 220 V, 820 µF and extended high-temperature endurance are required in general-purpose designs.
• High-temperature environments — Suitable for equipment that must sustain performance at elevated ambient temperatures up to 105°C for extended periods.
• Board or chassis-mounted power modules — Snap‑in radial can package (φ25×50 mm) supports secure mounting in compact power assemblies.

Unique Advantages

• Rated ripple‑current capability: 2.1 A at 120 Hz and 3.15 A at 50 kHz provide quantifiable ripple handling for both low- and high-frequency applications.
• Extended high-temperature life: 3000 hours endurance at 105°C under rated conditions ensures predictable aging and reliability for designs exposed to heat.
• Compact snap‑in form factor: φ25 × 50 mm radial, snap‑in can reduces assembly time and provides solid mechanical retention on the PCB or chassis.
• Controlled leakage: 1270 µA leakage current rating supports designs where leakage must be quantified and limited.
• Wide operating range: −40°C to 105°C operation and ±20% capacitance tolerance give designers clear operating envelopes for thermal and tolerance planning.
• Regulatory compliance: RoHS compliance aligns the part with common environmental requirements.
