LGU1H182MELZ

The LGU1H182MELZ is a snap‑in terminal aluminum electrolytic capacitor designed for general‑purpose power applications. It delivers 1.8 mF capacitance at a 50 V rating with ±20% tolerance and is specified for operation from −40°C to +105°C.

Engineered for sustained ripple handling and long endurance, this part offers defined low‑ and high‑frequency ripple current capabilities, low leakage, and a 3000‑hour life at 105°C—features that support robust power filtering and energy storage in production systems.

Key Features

• Capacitance & Voltage: 1.8 mF (1800 µF) nominal capacitance at a 50 V rated voltage with ±20% tolerance for predictable bulk energy storage.
• Snap‑in Can Package: Radial, snap‑in terminal construction in a φ22 × 25 mm can for secure board mounting and high mechanical stability.
• Temperature & Endurance: Rated for −40°C to +105°C operation and specified for 3000 hours endurance at 105°C under rated ripple conditions.
• Ripple Current Performance: Low‑frequency ripple current of 1.34 A (120 Hz) and high‑frequency ripple current of 1.541 A (50 kHz) to support filtering across a range of switching frequencies.
• Loss & Leakage: Specified tangent of loss angle (tan δ) of 0.30 at 20°C/120 Hz and leakage current of 900 µA, supporting stable performance in DC biased applications.
• Compliance & Packaging: RoHS compliant and supplied in tray packing for volume production readiness.

Typical Applications

• Power supply filtering: Bulk smoothing and ripple reduction where 50 V working voltage and rated ripple currents are required.
• Industrial control equipment: Energy reservoir and decoupling in general‑purpose industrial electronics operating within −40°C to +105°C.
• Consumer and commercial electronics: Bulk capacitance for DC bus stabilization and transient load support in mass‑produced systems.

Unique Advantages

• Defined endurance at high temperature: 3000 hours at 105°C ensures predictable aging behavior and lifecycle planning for high‑temperature deployments.
• Dual‑range ripple capability: Separate low‑frequency (1.34 A at 120 Hz) and high‑frequency (1.541 A at 50 kHz) ripple ratings enable designers to quantify performance across switching regimes.
• Compact snap‑in form factor: φ22 × 25 mm radial can with snap‑in terminals simplifies PCB mounting for production assemblies.
• Controlled dielectric loss and leakage: tan δ = 0.30 (20°C, 120 Hz) and 900 µA leakage current provide measurable electrical characteristics for circuit design.
• Production‑ready packaging: Tray packing and mass production status support high‑volume manufacturing workflows and handling.
• RoHS compliant: Meets RoHS requirements for environmental and regulatory conformity in many markets.
