LLS2A472MELB

The LLS2A472MELB is a snap-in terminal aluminum electrolytic capacitor from Nichicon’s LLS series, offering 4.7 mF (4700 µF) capacitance at a 100 V rated voltage. Designed for general-purpose power applications, it delivers high bulk capacitance in a radial, snap-in can package for board-mounted power filtering and energy storage.

Key value comes from its 85 °C standard rating with a 3000-hour endurance at 85 °C, substantial ripple-current capability at both low and high frequencies, and RoHS compliance—making it suitable for industrial and power-electronics designs that require stable bulk capacitance and long-term operation.

Key Features

• High Capacitance: 4.7 mF (4700 µF) nominal capacitance with ±20% tolerance, providing substantial bulk energy storage for smoothing and decoupling.
• 100 V Rated Voltage: Rated for 100 V DC operation, enabling use in higher-voltage power rails and applications requiring elevated DC withstand.
• Snap-in, Radial Can Package: Snap-in terminal mounting in a radial can (φ30×50L size) for secure board installation and simplified assembly in power assemblies.
• Ripple Current Performance: 5.26 A ripple current at 120 Hz and 6.049 A at 50 kHz, supporting high AC stress conditions and effective ripple suppression across frequency ranges.
• Endurance and Reliability: Endurance rated to 3000 hours at 85 °C withstanding rated ripple current, delivering predictable life under sustained thermal and electrical load.
• Electrical Characteristics: Tan δ (DF) of 0.20 at 20 °C/120 Hz and a specified leakage current of 2050 µA, allowing engineers to assess dissipation and leakage budgets precisely.
• Operating Temperature Range: −40 °C to +85 °C operating range to accommodate a broad set of industrial environments.
• Regulatory Compliance: RoHS compliant, meeting environmental directive requirements for restricted substances.

Typical Applications

• Power Supply Filtering: Bulk decoupling and smoothing in high-voltage DC power supplies where 4700 µF at 100 V provides stable hold-up and ripple reduction.
• Industrial Drives and Motor Control: Energy buffering and ripple suppression in motor-drive power stages and industrial inverter front-ends that require high-capacitance, board-mounted solutions.
• Energy Storage for Power Electronics: Local energy reservoir for converters and inrush mitigation in power-management circuits that need sustained capacitance under ripple load.
• General-Purpose Electronics: Applications requiring durable, high-capacitance polarized capacitors with long endurance at elevated temperatures.

Unique Advantages

• Long Endurance at Elevated Temperature: 3000-hour rating at 85 °C with rated ripple current ensures predictable performance over extended operation.
• High Ripple Current Capability: Specified ripple currents at both 120 Hz and 50 kHz give designers quantifiable margins for low- and high-frequency filtering tasks.
• Large Bulk Capacitance in Snap-in Form: 4700 µF in a φ30×50L snap-in can provides a compact, mountable solution for high-capacitance needs without custom packaging.
• Clear Electrical Parameters: Published tan δ and leakage current values (0.20 at 20 °C/120 Hz; 2050 µA) simplify thermal and leakage budgeting during design.
• Wide Operating Range: −40 °C to +85 °C supports a variety of environmental and industrial deployments.
• RoHS Compliant: Environmentally compliant construction reduces regulatory risk in product rollouts.
