LGU2Z471MELB

The LGU2Z471MELB is an aluminum electrolytic capacitor from Nichicon's LGU series featuring a snap‑in terminal, radial can package and a nominal capacitance of 470 µF at a rated voltage of 180 V. It is intended for general‑purpose electronic applications that require high‑voltage bulk capacitance with reliable long‑term endurance.

Designed for elevated operating temperatures, this part delivers a 3000‑hour life at 105 °C and supports significant ripple currents, offering stable performance across a –40 °C to +105 °C operating range.

Key Features

• Capacitance and Tolerance: 470 µF with ±20% tolerance at 120 Hz, 20 °C.
• Rated Voltage: 180 V DC nominal rating.
• Ripple Current Capability: 1.5 A at 120 Hz (low frequency) and 2.25 A at 50 kHz (high frequency), supporting higher AC stress conditions.
• Leakage Current: 870 µA specified leakage current after standard voltage application.
• Endurance: 3000 hours at 105 °C with DC bias plus rated ripple current applied, meeting capacitance, tan δ and leakage current criteria after recovery to 20 °C.
• Operating Temperature Range: –40 °C to +105 °C for reliable operation across a wide thermal envelope.
• Package and Mounting: Snap‑in radial can (φ30 × 25L) for secure board mounting; supplied in tray packing for mass production handling.
• Compliance: RoHS compliant to the stated directive.
• Polarized Design: Polar electrolytic capacitor suitable for DC circuits.

Typical Applications

• General Purpose Electronics — Suited for designs that require 470 µF bulk capacitance at 180 V in a snap‑in radial can form factor.
• High‑Temperature Systems — Applicable where components must withstand continuous operation at elevated temperatures up to 105 °C with specified endurance.
• High‑Ripple Current Circuits — Appropriate for circuits that impose significant ripple stress, leveraging the specified 1.5 A (120 Hz) and 2.25 A (50 kHz) ratings.

Unique Advantages

• Durable high‑temperature endurance: 3000 hours at 105 °C under rated ripple current helps ensure long service life in thermally demanding applications.
• Robust ripple handling: Distinct low‑ and high‑frequency ripple current ratings provide predictable behavior across typical power frequencies and higher switching frequencies.
• Compact snap‑in form factor: φ30 × 25L radial can with snap‑in terminals enables secure mechanical retention and simplified board installation.
• Low leakage for DC stability: Specified leakage current (870 µA) supports applications where minimising DC loss is important.
• Production‑friendly packaging: Tray packing supports automated handling and mass production workflows.
• Regulatory compliance: RoHS compliance supports use in regulated assemblies.
