LGU1K122MELA

The LGU1K122MELA from Nichicon is a snap‑in, radial can aluminum electrolytic capacitor in the LGU series designed for general‑purpose power applications. It delivers 1.2 mF capacitance at an 80 V rating in a compact φ25 × 25 mm package and is supplied in tray packing for production use.

Engineered for elevated operating conditions, this capacitor is specified for operation from −40°C to +105°C and is rated for 3000 hours of endurance at 105°C, supporting stable performance under sustained ripple and DC bias.

Key Features

• Capacitance & Voltage — 1.2 mF (1200 µF) nominal capacitance with an 80 V rated voltage and a tolerance of −20% to +20%, suitable for medium‑voltage smoothing and energy storage.
• Snap‑In Radial Can Package — Snap‑in terminal, radial can (φ25 × 25 mm) for secure board mounting and high current handling in compact layouts.
• High Temperature Endurance — Rated life of 3000 hours at 105°C, validated by endurance testing with DC bias plus rated ripple current.
• Ripple Current Capability — Low‑frequency ripple current 1.39 A at 120 Hz and high‑frequency ripple current 1.599 A at 50 kHz, enabling effective smoothing under AC ripple across frequency ranges.
• Low Loss and Leakage — Tangent of loss angle (tan δ) of 0.20 measured at 20°C, 120 Hz; specified leakage current 920 µA, supporting stable long‑term performance.
• Operating Range & Environmental — Operating temperature −40°C to +105°C and RoHS compliant; available in mass production with tray packing.

Typical Applications

• General‑purpose power filtering — Bulk smoothing and decoupling in power supply stages where 80 V rating and 1.2 mF capacitance are required.
• DC link and energy storage — Local energy reservoir for converters and power modules that operate within the −40°C to +105°C temperature range.
• High‑temperature environments — Applications requiring sustained ripple endurance, leveraging the 3000‑hour rating at 105°C for reliable operation.

Unique Advantages

• Robust thermal endurance — 3000 hours at 105°C assures designers of long‑term stability under elevated temperature and ripple stress.
• Frequency‑spanning ripple performance — Specified ripple currents at both 120 Hz and 50 kHz enable predictable behavior across common power frequencies.
• Compact, serviceable form factor — φ25 × 25 mm snap‑in can offers a small footprint while providing secure board retention for high‑current paths.
• Controlled electrical loss — tan δ = 0.20 (20°C, 120 Hz) gives a measurable indicator of ESR‑related losses for thermal and efficiency planning.
• RoHS compliant and production ready — Mass production status and RoHS compliance facilitate integration into commercial and industrial BOMs.
