LGN2X151MELB50

The LGN2X151MELB50 is an aluminum electrolytic capacitor in a snap-in terminal radial can designed for general-purpose power applications. It combines a 150 µF capacitance with a 600 V rated voltage in a smaller-sized case within the LGN series form factor.

Engineered for elevated-temperature operation, this snap-in capacitor is rated to operate up to 105°C and is RoHS compliant, providing robust ripple-current capability and long endurance under rated conditions.

Key Features

• Capacitance & Voltage — 150 µF nominal capacitance with a 600 V rated voltage and ±20% tolerance, suitable for high-voltage energy storage and filtering tasks.
• High-temperature Endurance — Designed for operation up to 105°C with an endurance rating of 2000 hours at 105°C when subjected to DC bias plus rated ripple current (applies to 600 V parts).
• Ripple Current Performance — Specified ripple current of 830 mA at 120 Hz and 1.187 A at 100 kHz, supporting sustained AC ripple conditions under rated bias.
• Compact Snap-In Package — Snap-in terminal, radial can package that occupies one rank smaller case size than LGU series parts while providing through‑board mechanical stability.
• Operating Temperature Range — Specified for −25°C to +105°C for the 600 V rating, enabling use in elevated-temperature environments.
• RoHS Compliant — Conforms to RoHS directive requirements (2011/65/EU, (EU)2015/863).
• Physical Dimensions — Compact footprint with size L: 5 × D: 3 cm and a seated maximum height of 1.969 inches, suitable for assemblies that require a smaller radial snap-in capacitor.
• Polarized Design — Polarized aluminum electrolytic construction for DC applications where polarity is maintained.

Typical Applications

• General Purpose Power — Useful in power supply filtering and energy storage where a high-voltage, high-temperature rated electrolytic capacitor is required.
• Industrial Electronics — Suitable for industrial control and power conversion modules that require robust ripple-current handling at elevated temperatures.
• Board-mounted Power Assemblies — Snap-in radial can package provides secure PCB mounting for cabinet and chassis-mounted power systems.

Unique Advantages

• 600 V Rating: Enables use in higher-voltage circuits without series stacking of lower-voltage capacitors.
• 105°C Capability: Supports extended operation at elevated temperatures for improved reliability in demanding environments.
• High Ripple Endurance: Specified ripple current ratings at both 120 Hz and 100 kHz allow designers to quantify thermal and ripple performance across frequency ranges.
• Smaller Case Size: One-rank smaller case than LGU-series parts reduces system footprint while preserving performance.
• Robust Endurance Specification: 2000 hours at 105°C under DC bias plus rated ripple current (for 600 V parts) provides a verifiable life metric for long-term designs.
• RoHS Compliance: Meets current RoHS requirements for restricted substances, simplifying regulatory compliance.
