LGX2H151MELA45

The LGX2H151MELA45 is an aluminum electrolytic, snap‑in terminal capacitor designed for high‑voltage power applications. It delivers 150 µF at 500 V in a compact radial can with a snap‑in mounting suitable for through‑hole assemblies.

Engineered as a long‑life assurance device, this part withstands rated ripple current for 5000 hours at 105°C and is specifically suited for rectifier circuits in general inverters and switching power supplies. It is RoHS compliant (2011/65/EU, (EU)2015/863).

Key Features

• Snap‑In Terminal Type: Radial, can‑style snap‑in mounting for secure, low‑profile through‑hole installation.
• High Voltage Capability: Rated voltage 500 V, supporting high‑voltage rectifier and power filter applications.
• 150 µF Capacitance, ±20% Tolerance: Nominal capacitance 150 µF with tolerance of −20% to +20% (±20% at 120 Hz, 20°C).
• 105°C Long‑Life Assurance: Endurance: rated ripple current applied for 5000 hours at 105°C with specified recovery criteria.
• Ripple Current Performance: Specified ripple handling of 1.08 A at 120 Hz and 1.544 A at 50 kHz for effective smoothing under AC bias.
• Operating Temperature Range: −25°C to +105°C for broad ambient tolerance in power systems.
• Leakage Current Specification: Leakage current meets I ≤ 3√(C·V) µA after 5 minutes' application of rated voltage at 20°C.
• Electrical Stability: For 450–500 V rating, tangent of loss angle (tan δ) is specified with a maximum of 0.20 (measured at 120 Hz, 20°C); low‑temperature impedance ratio Z(−25°C)/Z(+20°C) is 8 for 400–500 V range.

Typical Applications

• General Inverter Rectifiers: Use as rectifier smoothing capacitors in inverter front‑end circuits where high voltage and reliable long‑term ripple endurance are required.
• Switching Power Supplies: Filtering and energy storage in high‑voltage switching regulators and power conversion stages subject to elevated operating temperatures.
• Industrial Power Electronics: Bulk filtering and decoupling in industrial power modules and control systems that require robust high‑voltage capacitors.

Unique Advantages

• Long Operating Life: Rated to withstand rated ripple current for 5000 hours at 105°C, supporting extended maintenance intervals and predictable end‑of‑life behavior.
• High Ripple Handling: Explicit ripple current specifications at both low and high frequencies (120 Hz and 50 kHz) help designers size capacitors for real‑world switching and rectifier conditions.
• High Voltage in a Compact Can: 500 V rating combined with a smaller-sized radial can provides space savings while maintaining high‑voltage capability.
• Clear Electrical Limits: Leakage current and tan δ limits (including I ≤ 3√(C·V) µA and tan δ ≤ 0.20 at 500 V) give predictable performance benchmarks for design validation.
• Wide Temperature Range: −25°C to +105°C operating range supports a variety of ambient conditions encountered in power equipment.
• RoHS Compliant: Conforms to RoHS directive (2011/65/EU, (EU)2015/863) for chemical substance compliance in assembly environments.
