LGX2H820MELZ35

The LGX2H820MELZ35 is a snap‑in terminal aluminum electrolytic capacitor from Nichicon’s LGX series designed for long‑life power applications. It delivers 82 µF capacitance at a 500 V rating in a radial, can‑style snap‑in package suited for rugged mounting and power circuitry.

Engineered for power conversion environments, this capacitor is targeted at rectifier stages in inverters and switching power supplies where high voltage, steady ripple handling and extended high‑temperature endurance are required.

Key Features

• Electrical Performance — 82 µF nominal capacitance with ±20% tolerance and a 500 V rated voltage provide stable filtering in high‑voltage DC circuits.
• Ripple Handling — Rated ripple current of 720 mA at 120 Hz and 1.03 A at 50 kHz enables effective smoothing of AC‑to‑DC and high‑frequency switching currents.
• Reliability & Endurance — Long life assurance capable of withstanding 5000 hours of rated ripple current at 105°C; endurance limits specify capacitance change within ±20%, tan δ ≤ 200% of initial, and leakage current ≤ initial value after test.
• Thermal Range & Stability — Operating temperature from −25°C to +105°C with impedance stability defined (Z(−25°C)/Z(+20°C) up to 8 for the 450–500 V range) and a maximum tan δ specified for 450–500 V.
• Low Leakage — Leakage current specified as I ≤ 3√(C·V) µA after 5 minutes at 20°C, supporting low‑loss power designs.
• Package & Mounting — Radial, can‑style snap‑in terminal package with compact dimensions (L: 3.5 × D: 2.2 cm) for secure PCB attachment in power assemblies.
• Environmental Compliance — RoHS compliant (2011/65/EU, (EU)2015/863).

Typical Applications

• Inverter Rectifier Circuits — Designed for rectifier stages in general inverters where high voltage and sustained ripple current are encountered.
• Switching Power Supplies — Used for bulk filtering and smoothing on high‑voltage rails in switched‑mode power supplies.
• General Purpose Power Electronics — Suitable for a range of high‑voltage power conversion and regulation functions that require long life at elevated temperature.

Unique Advantages

• High Voltage Capability: 500 V rating enables use on higher DC bus voltages without series stacking.
• Extended Thermal Endurance: 5000 hours at 105°C specification ensures predictable aging and lifecycle behavior in hot operating environments.
• Strong Ripple Performance: Dual ripple‑current ratings for low and high frequency (720 mA at 120 Hz, 1.03 A at 50 kHz) address both rectified mains and switching noise.
• Secure Snap‑in Mounting: Radial snap‑in can package offers robust mechanical retention for power board assemblies.
• Measured Leakage & Dissipation Limits: Clear leakage current formula and tan δ limits aid thermal and loss budgeting in design validation.
• RoHS Compliance: Conforms to current RoHS directives for regulatory acceptance in commercial and industrial products.
