LGX2H101MELZ40

The LGX2H101MELZ40 is a snap-in terminal aluminum electrolytic capacitor from Nichicon’s LGX series. It is a 100 µF, 500 V polarized capacitor designed for general-purpose power applications where long-term high-temperature endurance and compact sizing are required.

Engineered for use in rectifier circuits, inverters and switching power supplies, the part delivers a combination of high-voltage capability, specified ripple performance and a long life assurance rating to support reliable power-filtering and energy-storage roles in industrial and power-electronics systems.

Key Features

• Capacitance & Voltage — 100 µF capacitance rated at 500 V, providing high-voltage energy storage in a single component.
• High-temperature Long Life — Rated for 5,000 hours at 105°C under rated ripple conditions, with endurance criteria (capacitance within ±20%, tan δ ≤ 200% of initial, leakage ≤ initial).
• Operating Temperature Range — Specified for operation from -25°C to +105°C to support a broad range of thermal environments.
• Ripple Current Performance — Specified ripple current of 770 mA at 120 Hz and 1.101 A at 50 kHz to handle AC ripple in rectifier and switching applications.
• Snap-in Mounting — Snap-in terminal, radial can package for through-hole PCB installation (package case: Radial, Can - Snap-In).
• Size and Form Factor — Smaller-sized can with dimensions approximately L: 4 cm × D: 2.2 cm for space-constrained designs.
• Polarized Design — Polarized aluminum electrolytic configuration suitable for DC filtering and energy storage.
• RoHS Compliant — Complies with the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Inverter Rectifier Circuits — Used for smoothing and energy buffering in the rectifier stages of general inverters.
• Switching Power Supplies — Provides bulk filtering and ripple handling in high-voltage supply rails for industrial and power-conversion systems.
• General Purpose Power Filtering — Suitable for DC link and smoothing functions where a 500 V, 100 µF polarized capacitor is required.

Unique Advantages

• Long-duration high-temperature rating: 5,000 hours endurance at 105°C ensures predictable performance over extended operating periods under rated ripple.
• High-voltage capability: 500 V rating allows use in higher-voltage power stages without series stacking.
• Matched ripple specifications: Listed ripple current values at 120 Hz (770 mA) and 50 kHz (1.101 A) let designers size input/output filters with quantifiable thermal stress limits.
• Compact snap-in package: Radial, snap-in can with approximately 4.0 × 2.2 cm dimensions delivers a smaller footprint for PCB-mounted power modules.
• Wide operating temperature: -25°C to +105°C rating supports deployments across varied industrial thermal environments.
• Regulatory compliance: RoHS compliance supports use in regions requiring restricted-substance conformance.
