LGU1K821MELZ

The LGU1K821MELZ from Nichicon is a snap‑in terminal aluminum electrolytic capacitor in the LGU series, offering 820 µF capacitance at an 80 V rating with ±20% tolerance. Designed for general‑purpose power applications, it delivers specified ripple handling and long endurance for sustained operation in commercial and industrial equipment.

Key performance attributes include rated ripple current at both low and high frequencies, a 3000‑hour endurance at 105°C, low leakage, and a compact radial can snap‑in package (φ22×25L) suitable for board‑level power smoothing and energy storage tasks.

Key Features

• Capacitance & Tolerance — 820 µF nominal capacitance with ±20% tolerance (measured at 120 Hz, 20°C).
• Rated Voltage — 80 V DC rating for higher‑voltage power rails and bulk energy applications.
• Ripple Current Capability — 1.11 A at 120 Hz (low frequency) and 1.276 A at 50 kHz (high frequency) to support AC ripple and switching workloads.
• Endurance — Specified to withstand 3000 hours of D.C. bias plus rated ripple current at 105°C with defined limits on capacitance change, tan δ, and leakage current.
• Leakage Current — 760 µA specified leakage current after rated voltage application (measured conditions per product data).
• Operating Temperature — Rated for −40°C to +105°C operation to cover a wide ambient range.
• Package & Mounting — Snap‑in terminal, radial can (φ22×25L / 22 mm × 25 mm) for secure board mounting and mechanical stability.
• Regulatory — RoHS compliant.
• Production & Packing — Mass production status with tray packing for volume assembly processes.

Typical Applications

• Power supply smoothing — Bulk capacitance for filtering and smoothing on medium‑voltage DC rails where 80 V rating and high ripple capability are required.
• Switching power supplies — Supports DC bias plus rated ripple current in applications with both low‑ and high‑frequency ripple components.
• Industrial and commercial equipment — General‑purpose energy storage and decoupling where extended endurance at elevated temperature (3000 h at 105°C) is necessary.

Unique Advantages

• High voltage margin: 80 V rating provides headroom for higher‑voltage rails compared to lower‑voltage electrolytics.
• Dual‑frequency ripple performance: Specified ripple current at both 120 Hz and 50 kHz enables reliable use with linear and switching power sources.
• Long endurance at elevated temperature: 3000 hours at 105°C supports sustained operation under thermal stress and continuous ripple loading.
• Compact, robust snap‑in package: φ22×25L radial can with snap‑in terminals for secure mechanical retention and straightforward PCB integration.
• Low leakage: 760 µA leakage current for stable long‑term performance after voltage application.
• Production ready: Tray packing and mass production status simplify procurement and assembly for volume designs.
