LGU2W101MELA

The LGU2W101MELA is a snap‑in terminal aluminum electrolytic capacitor from Nichicon's LGU series. It delivers 100 µF capacitance at a 450 V rating with a ±20% tolerance and is polarized for general‑purpose applications.

Designed for sustained high‑temperature operation, this part is specified for –25 °C to +105 °C operation and is capable of withstanding 3000 hours of rated ripple current at 105 °C. The radial, snap‑in can and tray packing make it suitable for mass production assembly.

Key Features

• Core Type: Aluminum electrolytic, polarized capacitor in a snap‑in terminal configuration for secure PCB mounting.
• Rated Voltage & Capacitance: 450 V rated voltage with 100 µF capacitance and ±20% tolerance (measured at 120 Hz, 20 °C).
• Operating Temperature & Endurance: Specified for –25 °C to +105 °C; endurance rating includes 3000 hours at 105 °C under DC bias plus rated ripple current.
• Ripple Current Specification: Rated ripple current values include 690 mA at 120 Hz and 986.7 mA at 50 kHz, enabling predictable thermal loading under AC ripple conditions.
• Leakage Current: Defined by I ≤ 3CV(µA) after 5 minutes’ application of rated voltage at 20 °C for predictable leakage behavior.
• Package & Mounting: Radial can, snap‑in package with size φ25 × 30 mm (L: 3 × D: 2.5 cm). Supplied in tray packing for production throughput.
• Compliance: RoHS‑compliant per the provided product data.

Typical Applications

• General‑purpose power equipment: Suited for designs that require a 450 V, 100 µF polarized capacitor with robust temperature and ripple endurance.
• High‑voltage filter and smoothing: Use where rated ripple current handling and long‑term thermal endurance at 105 °C are required.
• OEM mass‑production assemblies: Tray packing and snap‑in terminals support efficient insertion and retention in high‑volume manufacturing.

Unique Advantages

• High‑voltage capability: 450 V rating enables deployment in higher DC voltage circuits without up‑rating multiple components.
• Proven high‑temperature endurance: Specified to withstand 3000 hours at 105 °C under rated ripple current for predictable long‑term performance.
• Documented ripple handling: Published ripple current figures at 120 Hz and 50 kHz allow thermal and lifetime calculations based on actual conditions.
• Production‑friendly packaging: Radial, snap‑in can and tray packing streamline assembly for volume manufacturing.
• Predictable leakage behavior: Leakage current bound by I ≤ 3CV(µA) after rated voltage application for reliable leak current budgeting.
• Regulatory compliance: RoHS status provided for environmental conformance in finished products.
