The LGU2Z821MELA is a snap‑in terminal aluminum electrolytic capacitor from Nichicon's LGU series, offering 820 µF capacitance at a 180 V rating. Designed for general‑purpose power applications, it provides bulk energy storage and ripple handling in a compact φ25 × 40 mm can with snap‑in mounting and tray packing.

Key value propositions include high temperature endurance (rated for −40°C to 105°C with 3000 hours life at 105°C), measurable ripple current capability at both low and high frequencies, and RoHS compliance for environmental compatibility.

Key Features

• Capacitance & Voltage — 820 µF nominal capacitance with a 180 V rated voltage and ±20% tolerance, providing substantial bulk capacitance for DC link and filtering duties.
• Snap‑In Terminal Package — Radial, can‑type snap‑in mounting for secure board retention and straightforward PCB assembly using snap‑in terminals.
• High Temperature Endurance — Rated for operation from −40°C to 105°C with a specified endurance of 3000 hours at 105°C under rated ripple and DC bias conditions.
• Frequency‑rated Ripple Capability — Specified low‑frequency ripple current of 2.04 A at 120 Hz and high‑frequency ripple current of 3.06 A at 50 kHz, enabling dependable performance across a range of switching and line frequencies.
• Electrical Loss and Leakage — Tangent of loss angle (tan δ) of 0.15 measured at 20°C, 120 Hz, and a specified leakage current of 1150 µA after voltage application per the product data.
• Form Factor — Compact φ25 × 40 mm can (dimension L: 4 cm × D: 2.5 cm) that balances capacitance density and board space; provided in tray packing for production handling.
• Regulatory Compliance — RoHS compliant, aligning with restricted substances requirements referenced in the product data.

Typical Applications

• General‑purpose power filtering — Bulk capacitance and specified ripple current support smoothing of DC supplies and reduction of low‑ and high‑frequency ripple components.
• DC bus decoupling — 820 µF at 180 V provides energy buffering for DC link circuits in power conversion subsystems where snap‑in mounting is preferred.
• Power supply bulk storage — Designed for systems requiring robust capacitance over a wide temperature range with long endurance at elevated temperature.

Unique Advantages

• High temperature endurance: 3000 hours rated life at 105°C ensures stability of capacitance and leakage under sustained elevated temperatures.
• Dual‑frequency ripple spec: Defined ripple current values at 120 Hz and 50 kHz let designers evaluate performance for both line‑frequency and switching converters.
• Compact snap‑in form: φ25 × 40 mm can with snap‑in terminals simplifies mechanical retention and PCB assembly for production builds.
• Measurable loss characteristics: tan δ = 0.15 (20°C, 120 Hz) provides a quantifiable dissipation factor for thermal and stability calculations.
• RoHS compliance and production readiness: Environmentally compliant and listed as mass production with tray packing for manufacturing integration.
