LGU2P821MELB

The LGU2P821MELB is a snap‑in terminal aluminum electrolytic capacitor from Nichicon's LGU series, rated at 820 µF and 220 V. It is a radial, can‑style snap‑in component designed for general‑purpose applications that require high ripple endurance and long operational life at elevated temperature.

Engineered for sustained operation up to 105 °C with a 3000‑hour endurance rating, this unit delivers stable capacitance, controlled loss angle, and substantial ripple current capability for demanding power environments.

Key Features

• Capacitance & Voltage — 820 µF nominal capacitance with a rated voltage of 220 V and a capacitance tolerance of ±20% (measured at 120 Hz, 20 °C).
• High‑temperature Endurance — Rated for operation from −40 °C to 105 °C with a specified life of 3000 hours at 105 °C under D.C. bias plus rated ripple current.
• Ripple Current Performance — Low‑frequency ripple current of 2.1 A at 120 Hz and high‑frequency ripple current of 3.15 A at 50 kHz, providing robust capability for applications with significant AC components.
• Low Loss Characteristics — Tangent of loss angle (tan δ) specified per series: for the 160–420 V range tan δ (max.) is 0.15 at 120 Hz, 20 °C, supporting efficient energy handling.
• Leakage Current — Specified leakage current of 1270 µA (after 5 minutes’ application of rated voltage at 20 °C as per series definition).
• Mechanical & Packaging — φ30 × 40 mm can (L: 4 × D: 3 cm) in a radial, snap‑in package; supplied in tray packing and available in mass production quantities.
• RoHS Compliant — Conforms to RoHS directive requirements.

Typical Applications

• General‑purpose power systems — Provides bulk capacitance and ripple handling in power assemblies where 220 V rated voltage and 820 µF capacitance are required.
• High‑temperature electronic equipment — Suited for systems operating up to 105 °C thanks to its 3000‑hour endurance rating at that temperature.
• AC ripple‑bearing circuits — Designed to withstand sustained rated ripple current at both low and high frequencies as specified (2.1 A at 120 Hz; 3.15 A at 50 kHz).

Unique Advantages

• Long operational life: 3000 hours at 105 °C with rated ripple current, enabling predictable aging and maintenance planning in high‑temperature deployments.
• High ripple capacity across frequencies: Specified ripple current values at 120 Hz and 50 kHz support use in both low‑frequency and higher‑frequency power stages.
• Compact snap‑in form factor: φ30 × 40 mm radial snap‑in can simplifies board mounting and secures robust mechanical retention for vertical assemblies.
• Measured electrical stability: Capacitance tolerance ±20% and a defined tan δ (max. 0.15 for the applicable voltage range) provide predictable behavior for filter and energy storage designs.
• Production readiness: Tray packing and mass production status support volume procurement and streamlined assembly operations.
• Regulatory compliance: RoHS compliance supports designs targeting restricted‑substance requirements.
