LGX2H680MELA25

The LGX2H680MELA25 is a snap‑in terminal type aluminum electrolytic capacitor from Nichicon's LGX series. It provides 68 µF capacitance at a 500 V rating in a compact radial can snap‑in package, designed for general-purpose power applications.

Engineered for long life at elevated temperature, this part withstands 5000 hours of rated ripple current at 105°C and is suited for rectifier circuits in general inverters and switching power supplies. The product is RoHS compliant.

Key Features

• Electrical Characteristics — Rated capacitance 68 µF with ±20% tolerance and rated voltage 500 V; polarized aluminum electrolytic construction suitable for DC filter and energy storage roles.
• High‑Voltage, High‑Ripple Capability — Designed to handle rated ripple current with specified values of 650 mA at 120 Hz (low frequency) and 929.5 mA at 50 kHz (high frequency).
• Long Life Assurance — Endurance specified as 5000 hours at 105°C with DC bias plus rated ripple current; after test, capacitance change within ±20% and leakage current remains at or below initial specified value.
• Temperature Range & Stability — Operating temperature range from −25°C to +105°C; low‑temperature impedance stability specified (Z(−25°C)/Z(+20°C) up to 8 for 400–500 V range).
• Mechanical & Mounting — Snap‑in radial can package with compact dimensions (L: 2.5 × D: 2.5 cm) and snap‑in mounting for secure PCB installation.
• Loss and Leakage Control — Tangent of loss angle (tan δ) specified (max. 0.20 for 450–500 V) and leakage current defined by series formula I ≤ 3√CV (μA) after 5 minutes at 20°C.
• Shelf Life & Reliability — Shelf life test: stored at 105°C for 1000 hours then voltage treatment; capacitance change within ±15%, tan δ within 150% of initial, leakage current within initial specified value.
• Regulatory — Compliant to the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Rectifier circuits for inverters — Supports DC filtering and smoothing in rectifier stages of general inverter designs where high voltage and long life are required.
• Switching power supplies — Provides bulk capacitance and ripple handling for high‑voltage sections of switching PSUs.
• General purpose power electronics — Useful where compact, snap‑in high‑voltage electrolytic capacitors are needed for energy storage, filtering, or decoupling in industrial power modules.

Unique Advantages

• Long elevated‑temperature endurance: Rated to withstand 5000 hours at 105°C with rated ripple current, enabling longer service life in hot operating environments.
• High voltage capability: 500 V rating supports higher‑voltage rectifier and power conversion stages without series stacking.
• Compact snap‑in form factor: Radial can snap‑in package with small footprint simplifies PCB layout while providing reliable mechanical retention.
• Defined ripple performance: Specified ripple current values at both 120 Hz and 50 kHz help designers size capacitors for expected operating frequencies.
• Measurable stability and loss parameters: Clear tan δ and low‑temperature impedance limits allow predictable behavior across temperature and voltage conditions.
• RoHS compliant: Meets 2011/65/EU and (EU)2015/863 requirements for restricted substances.
