LGUW6101MELZ

The LGUW6101MELZ is a snap‑in terminal aluminum electrolytic capacitor from Nichicon’s LGU series. It delivers 100 µF capacitance at a 420 V rating in a compact φ22 × 30 mm can, designed for general‑purpose high‑voltage power assemblies where elevated temperature endurance and ripple handling are required.

Key value comes from its 105°C, 3000‑hour endurance, high frequency and low frequency ripple capability, low leakage current, and snap‑in package suitable for robust mounting and tray packing in volume production.

Key Features

• Capacitance & Voltage — 100 µF nominal capacitance with a 420 V rated voltage and ±20% tolerance (measured at 120 Hz, 20°C), providing stable bulk capacitance for high‑voltage circuits.
• High Temperature Endurance — Rated for operation to 105°C with an endurance specification of 3000 hours at 105°C under DC bias plus rated ripple current.
• Ripple Current Performance — Handles 700 mA at 120 Hz (low frequency) and 1.001 A at 50 kHz (high frequency), supporting designs with significant AC ripple on DC rails.
• Low Leakage — Specified leakage current of 610 µA supports low standby losses and predictable behavior after voltage application.
• Package & Mounting — Radial can with snap‑in terminals (φ22 × 30 mm) for secure board mounting; supplied in tray packing and available in mass production quantities.
• Temperature Range — Operating range from −25°C to +105°C suitable for elevated ambient conditions encountered in power electronics.
• Environmental Compliance — Compliant with RoHS requirements.

Typical Applications

• High‑voltage power supplies — Bulk energy storage and decoupling on 420 V rails where high ripple handling and 105°C endurance are needed.
• Industrial power electronics — Suitable for power assemblies and modules that require durable, snap‑in mounted capacitors for reliable board installation.
• Inverter and converter circuits — Used where a combination of high voltage rating, substantial ripple current capability, and long endurance are required.

Unique Advantages

• Long high‑temperature life — 3000 hours at 105°C provides predictable long‑term performance in hot operating environments.
• High ripple capability across frequencies — Rated ripple currents at both 120 Hz and 50 kHz address low‑ and high‑frequency ripple stress in power systems.
• Compact high‑voltage form factor — 100 µF at 420 V in a φ22 × 30 mm can saves space on power boards while meeting high voltage requirements.
• Secure snap‑in mounting — Snap‑in terminals facilitate robust mechanical retention for assemblies subject to vibration or handling.
• Low leakage current — 610 µA leakage supports designs where minimized DC leakage is beneficial for performance and thermal management.
• Production readiness — Tray packing and mass production status simplify procurement and assembly planning for volume builds.
