LGU2C821MELA

The LGU2C821MELA from Nichicon is a snap-in terminal aluminum electrolytic capacitor in the LGU series, specified for general-purpose power applications. It delivers 820 µF capacitance at a 160 V rating and is designed to operate across a wide temperature range of –40°C to 105°C.

Built for sustained ripple duty, this radial can (snap-in) capacitor provides specified ripple-current endurance and long-term reliability, with RoHS compliance and tray packing for production use.

Key Features

• Capacitance & Voltage — 820 µF nominal capacitance with a 160 V rated voltage and ±20% tolerance, suitable for bulk energy storage in general-purpose power designs.
• High-Temperature Endurance — Rated life of 3000 hours at 105°C with applied rated ripple current, supporting long-term operation under elevated temperature stress.
• Ripple Current Capability — Low-frequency ripple current of 2.04 A (120 Hz) and high-frequency ripple current of 3.06 A (50 kHz), enabling robust AC current handling across common frequency ranges.
• Leakage and Dissipation — Leakage current specified at 1080 µA and loss tangent (tanδ) of 0.15 (measured at 20°C, 120 Hz), providing predictable power loss and self-heating characteristics.
• Mechanical & Mounting — Snap-in terminal, radial can package (φ25 × 35L) in tray packing for assembly-friendly handling and secure PCB mounting.
• Environmental Compliance — RoHS compliant and available as a mass-production part from Nichicon.

Typical Applications

• Industrial Power Systems — Suited for general-purpose power applications that require a 160 V rating and sustained ripple handling at elevated temperatures.
• Commercial Power Electronics — Applicable where long endurance at 105°C and reliable leakage/DF characteristics are needed over extended operating periods.
• Bulk Energy Storage — Useful in designs requiring substantial capacitance (820 µF) for energy buffering and charge storage in general-purpose circuits.

Unique Advantages

• Designed for sustained ripple duty: Endurance tested for 3000 hours at 105°C with rated ripple current, supporting continuous operation under load.
• Broad ripple-frequency performance: Specified ripple current at both 120 Hz and 50 kHz (2.04 A and 3.06 A respectively) to accommodate a range of power-frequency and switching environments.
• Predictable electrical behavior: Defined tanδ (0.15 at 20°C, 120 Hz) and leakage current (1080 µA) enable designers to estimate loss and standby current reliably.
• Assembly-friendly format: Snap-in radial can with tray packing for straightforward PCB mounting and production handling.
• Regulatory-compliant production: RoHS compliant and available in mass-production status from Nichicon for volume sourcing.
