LLS1K472MELC

The LLS1K472MELC from Nichicon is a snap-in terminal aluminum electrolytic capacitor in the LLS series, designed for general-purpose power electronics. It provides 4.7 mF (4700 µF) capacitance at an 80 V rated voltage with high ripple-current capability and long endurance for demanding DC-bias and ripple conditions.

Engineered for applications that require robust bulk energy storage and ripple smoothing, this snap-in radial can delivers measurable performance with a compact φ35 × 30 mm package and RoHS compliance for broad deployment.

Key Features

• Capacitance and Voltage — 4.7 mF (4700 µF) nominal capacitance with an 80 V rated voltage and ±20% tolerance (120 Hz, 20°C) for reliable high-voltage bulk storage.
• High Ripple Current Handling — 4.12 A at 120 Hz (low frequency) and 4.738 A at 50 kHz (high frequency), enabling effective smoothing under AC ripple across a range of operating frequencies.
• Endurance — Specified to withstand 3000 hours of rated ripple current at 85°C, meeting the LLS series endurance requirement for sustained high-stress operation.
• Operating Temperature Range — Rated for operation from −40°C to +85°C to cover typical industrial and commercial environments.
• Leakage Current — Measured leakage current of 1830 µA, specified per product data for design and system leakage budgeting.
• Package and Mounting — Snap-in radial can (φ35 × 30 mm) for secure PCB mounting; supplied in tray packing for mass-production handling.
• Compliance and Marking — RoHS compliant; marked with white lettering on a black sleeve as specified in the LLS series datasheet.
• Polarized Device — Designed as a polarized electrolytic capacitor for DC applications.

Typical Applications

• Power supplies and converters — Bulk filtering and smoothing where an 80 V rating and high capacitance reduce voltage ripple and stabilize DC rails.
• Power electronics — Energy storage and ripple absorption in general-purpose industrial power circuits subject to sustained ripple currents.
• Industrial equipment — Use in assemblies that require durable performance at up to +85°C and long endurance under rated ripple conditions.

Unique Advantages

• High-voltage, high-capacitance combination — 4700 µF at 80 V provides substantial energy density for designs that require both voltage margin and bulk storage in a single component.
• Measured ripple capability across frequencies — Specified ripple current values at 120 Hz and 50 kHz support designers addressing both low- and high-frequency ripple environments.
• Long endurance at elevated temperature — 3000 hours at 85°C under rated ripple conditions ensures predictable life and stable performance for long-term installations.
• Secure snap-in mounting — Radial snap-in can reduces the need for additional mechanical fixation, simplifying assembly for high-current PCB layouts.
• Production-ready supply — Tray packing and mass production status ease procurement and volume manufacturing logistics.
• Regulatory compliance — RoHS compliance supports use in regions and projects with restricted-substance requirements.
