LGU1H392MELZ

The LGU1H392MELZ from Nichicon is a snap‑in terminal aluminum electrolytic capacitor delivering 3.9 mF (3900 µF) at 50 V with ±20% tolerance. Built for general‑purpose power applications, it combines high ripple‑current capability and 105°C endurance to support demanding power‑handling roles in industrial and power‑electronics designs.

Key Features

• Capacitance & Voltage — 3.9 mF (3900 µF) rated at 50 V to provide bulk energy storage and smoothing in DC power rails.
• Tolerance & Polarization — ±20% capacitance tolerance; polarized capacitor suitable for standard DC circuits.
• High Temperature Endurance — Rated for 3000 hours at 105°C, ensuring stable performance under elevated operating temperatures.
• Ripple Current Performance — 2.25 A at 120 Hz (low frequency) and 2.5875 A at 50 kHz (high frequency), enabling robust AC ripple handling across a range of switching and line frequencies.
• Low Leakage — Leakage current specified at 1320 µA, supporting efficient long‑term operation after voltage application.
• Loss Angle (tan δ) — tan δ = 0.30 measured at 20°C, 120 Hz for predictable dissipation characteristics.
• Mechanical & Mounting — Snap‑in radial can package (φ22 × 40 mm body / L: 4 × D: 2.2 cm, Height seated max 1.575 in) for secure panel or chassis mounting and straightforward assembly.
• Production & Packaging — Tray packing and mass production status for consistent supply and board‑level handling.
• RoHS Compliant — Meets RoHS directive requirements for regulated substances.

Typical Applications

• Power supply filtering — Bulk smoothing and decoupling on 50 V DC rails where high capacitance and ripple handling are required.
• Industrial power electronics — Energy storage and ripple absorption in converters and motor drive systems operating up to 105°C ambient.
• General‑purpose power systems — Use in rack‑mounted or chassis‑mounted equipment that requires reliable, high‑temperature endurance capacitors with snap‑in mounting.

Unique Advantages

• High ripple tolerance: Dual ripple‑current ratings (2.25 A @ 120 Hz, 2.5875 A @ 50 kHz) support both line‑frequency and switching environments without compromising lifetime.
• Extended high‑temperature life: 3000 hours endurance at 105°C provides predictable long‑term behavior for thermal‑stress applications.
• Compact snap‑in form factor: φ22 × 40 mm radial can with snap‑in terminals enables secure mechanical retention and simplified assembly in power assemblies.
• Controlled dissipation and leakage: Specified tan δ and leakage current parameters help designers budget power loss and stand‑by current precisely.
• Production readiness: Tray packing and mass production availability support volume builds and consistent supply chain handling.
• Regulatory compliance: RoHS compliance supports deployments where restricted‑substance conformance is required.
