LGN2H151MELZ50

The LGN2H151MELZ50 is a Nichicon LGN series aluminum electrolytic capacitor in a snap-in terminal (radial can) package. It delivers 150 µF capacitance at a 500 V rating and is intended for general-purpose applications requiring high-voltage capacitance in a compact snap-in form factor.

Designed for extended high-temperature operation, this part is specified for operation from −25 °C to +105 °C with endurance testing at 105 °C for 3000 hours, making it suitable where sustained ripple handling and long-term stability are required.

Key Features

• High Rated Voltage — 500 V rated voltage suitable for high-voltage designs that require robust DC energy storage.
• Nominal Capacitance & Tolerance — 150 µF with ±20% tolerance (–20% to +20%), specified at 120 Hz, 20 °C.
• Thermal Endurance — Rated for 3000 hours at 105 °C under DC bias plus rated ripple current, supporting sustained high-temperature operation.
• Ripple Current Performance — Low-frequency ripple: 750 mA (120 Hz); high-frequency ripple: 1.073 A (100 kHz), enabling effective ripple handling across frequency ranges.
• Low Dissipation Factor — tan δ = 0.20 measured at 20 °C, 120 Hz, supporting predictable AC losses in power circuits.
• Leakage Current — Specified leakage current of 820 µA after standard voltage application, supporting stable leakage characteristics.
• Compact Snap-in Package — Radial, snap-in can with dimensions φ22 × 50 mm (D × L) and tray packing for convenient handling and assembly.
• RoHS Compliant — Conforms to RoHS directive requirements.

Typical Applications

• General-purpose power systems — Energy storage and smoothing where a 500 V-rated electrolytic is required and a snap-in footprint is preferred.
• High-temperature environments — Circuits that require sustained operation at elevated temperatures up to 105 °C with long endurance.
• AC/DC and DC/DC converter support — Applications needing bulk capacitance and reliable ripple current handling across low and high frequencies.

Unique Advantages

• 500 V capability: Allows use in high-voltage circuits without stacking or series combinations.
• Long high-temperature endurance: 3000-hour rating at 105 °C for sustained performance under continuous load and ripple conditions.
• Dual-frequency ripple handling: Specified ripple currents at both 120 Hz and 100 kHz provide clear guidance for design across frequency ranges.
• Predictable loss and leakage: tan δ = 0.20 and leakage current 820 µA give measurable electrical stability for power designs.
• Compact snap-in form factor: φ22 × 50 mm radial can offers a smaller case size within the LGN family, simplifying layout in space-constrained designs.
• Production-ready packaging: Tray packing and mass-production status support procurement and assembly requirements.
