LGU1K222MELB

The LGU1K222MELB is a Nichicon LGU‑series aluminum electrolytic capacitor in a snap‑in radial can designed for general‑purpose applications. It delivers 2.2 mF (2200 µF) capacitance at an 80 V rating with electrolytic construction and snap‑in terminals for secure board mounting.

Engineered for elevated‑temperature operation and sustained ripple loading, this part targets designs that require high capacitance, reliable low‑frequency and high‑frequency ripple handling, and extended endurance at up to 105°C.

Key Features

• Electrical Capacity — 2.2 mF (2200 µF) capacitance with ±20% tolerance at 120 Hz, 20°C for stable bulk energy storage.
• Voltage Rating — Rated for 80 V applications, suitable where higher DC voltage capability is required.
• Ripple Current Performance — Handles 2.1 A ripple current at 120 Hz (low frequency) and 2.415 A at 50 kHz (high frequency), supporting designs with significant AC ripple exposure.
• Loss and Leakage — Low dissipation factor with tanδ = 0.20 at 20°C, 120 Hz and specified leakage current of 1250 µA for this part.
• High‑Temperature Endurance — Rated for operation from −40°C to 105°C with 3000 hours endurance at 105°C under rated ripple and DC bias.
• Package and Mounting — φ30 × 25 mm radial can with snap‑in terminals; supplied in tray packing for production assembly.
• Regulatory Status — RoHS compliant as declared in product data.

Typical Applications

• General‑Purpose Power Filtering — Bulk smoothing and filtering where 80 V rating and 2200 µF capacitance are required.
• High Ripple Environments — Circuits that demand sustained low‑ and high‑frequency ripple handling up to the specified ripple currents.
• High‑Temperature Systems — Designs that operate at elevated temperatures and require 3000 hours of endurance at 105°C.
• Snap‑In Assembly Designs — Boards and assemblies that use snap‑in radial can capacitors for secure mechanical mounting and tray‑based production handling.

Unique Advantages

• High Capacitance at Elevated Voltage: 2200 µF at 80 V provides substantial bulk energy storage for higher‑voltage rails.
• Dual‑Frequency Ripple Capability: Rated ripple currents at both 120 Hz (2.1 A) and 50 kHz (2.415 A) support a range of switching and line‑frequency conditions.
• Designed for 105°C Endurance: 3000‑hour life rating at 105°C ensures predictable performance in thermally demanding environments.
• Controlled Dielectric Loss: tanδ of 0.20 at 20°C and 120 Hz aids predictable ESR‑related behavior in filtering and decoupling roles.
• Production‑Friendly Packaging: Tray packing and snap‑in terminals simplify handling and through‑hole assembly for medium‑to‑high volume production.
• RoHS Compliant: Meets environmental directive requirements for restricted substances as reported in product data.
