LGR2G820MELA25

The LGR2G820MELA25 is a snap-in terminal aluminum electrolytic capacitor rated at 400 V with 82 µF capacitance. It is part of Nichicon’s LGR long-life series, designed for general-purpose power applications where extended lifetime and robust ripple handling are required.

This capacitor combines a compact 25 mm diameter radial can with snap-in mounting and long-life assurance (10000 hours at 105°C), making it suitable for power systems that require reliable bulk capacitance and sustained performance at elevated temperatures.

Key Features

• Rated Capacitance & Voltage — 82 µF nominal capacitance at a 400 V rated voltage with ±20% tolerance.
• Long-Life Endurance — Qualified for 10000 hours at 105°C under rated ripple conditions; after endurance testing capacitance change is within ±25% and leakage current remains at or below initial specified value.
• Operating Temperature Range — Specified for –25°C to 105°C for the 400 V rating.
• Mounting & Package — Snap-in terminal, radial can package with overall dimensions approximately 25 mm × 25 mm (D × L), designed for secure PCB insertion and mechanical stability.
• Ripple Current Capability — Rated ripple current of 640 mA at 120 Hz and 915.2 mA at 50 kHz for this part, with frequency coefficients for 400 V shown in the series data (e.g., 1.00 at 120 Hz, up to ~1.43 at ≥50 kHz).
• Leakage Current Specification — Leakage current meets I ≤ 3√(C·V) µA after 5 minutes’ application of rated voltage at 20°C, per series datasheet.
• Dissipation Factor (tan δ) — tan δ specified in series data (≤0.15 for rated voltages 200–400 V at 120 Hz, 20°C), providing a reference for loss behavior at typical test conditions.
• RoHS Compliant — Manufactured in compliance with RoHS directives as noted for the LGR series.
• Polarized Electrolytic — Polarized design for use in DC-biased circuits; observe polarity in assembly and service.

Typical Applications

• Power supply filtering — Bulk smoothing and energy storage on 400 V DC rails where extended lifetime at elevated temperature is required.
• Industrial power systems — General-purpose decoupling and ripple absorption in industrial control and power conversion equipment designed for long service intervals.
• High-voltage assemblies — Snap-in mounting provides a robust mechanical and electrical solution for equipment using 400 V rated electrolytic capacitance.

Unique Advantages

• Long operational life: 10000 hours at 105°C rating provides predictable endurance for maintenance planning and reliability projections.
• High-voltage capability: 400 V rating enables use on higher DC rails without series stacking, reducing board complexity.
• Compact snap-in form factor: 25 mm diameter radial can with snap-in terminals simplifies PCB mounting while delivering substantial bulk capacitance.
• Measured ripple handling: Specified ripple currents at 120 Hz and 50 kHz and frequency coefficients in the series data allow designers to size devices for expected operating frequencies.
• Verified electrical characteristics: Clear datasheet limits for leakage current and dissipation factor support predictable performance during design and qualification.
• RoHS compliance: Manufactured to meet RoHS requirements for environmentally conscious designs.
