LLS2G471MELB

The LLS2G471MELB is a snap-in terminal aluminum electrolytic capacitor in Nichicon’s LLS series, rated for 400 V and 470 µF with ±20% tolerance. Designed for general-purpose power applications, it combines high-voltage capacitance with snap-in mounting for secure mechanical and electrical connections in production assemblies.

Key performance attributes include a low loss tangent at 20°C/120 Hz, robust ripple-current capability at both low and high frequencies, and a documented 3000-hour endurance at 85°C, making it suitable for designs that require stable DC-side energy storage under continuous load.

Key Features

• Capacitance and Voltage — 470 µF capacitance at a 400 V rated voltage with ±20% tolerance for predictable energy storage and decoupling.
• Snap-In Radial Can Package — Snap-in terminal mounting in a radial, can-style package for secure board installation and suitability for production assembly; tray packing supports mass production.
• Low Loss Tangent — tanδ specified at 0.15 (measured at 20°C and 120 Hz) to minimize dissipation in AC/ ripple environments.
• High Ripple Current Capability — 2510 mA at 120 Hz (low frequency) and 3589.3 mA at 50 kHz (high frequency) for effective ripple handling across common power-system frequencies.
• Leakage Current — Specified leakage current of 1300 µA after rated voltage application, supporting predictable leakage behavior in system bias conditions.
• Endurance and Temperature Range — Rated for 3000 hours at 85°C with an operating temperature range of −25°C to +85°C; endurance validated under DC bias plus rated ripple current.
• Physical Size — Compact footprint with a diameter of 30 mm and length of 45 mm (φ30 × 45L; L: 4.5 × D: 3 cm) for high-voltage capacitor applications where board space and mounting reliability matter.
• RoHS Compliant — Manufactured in compliance with RoHS requirements.

Typical Applications

• General Purpose — High-Voltage DC Systems — Use where a 400 V, 470 µF snap-in capacitor is required for energy storage or voltage smoothing.
• General Purpose — Ripple-Handling Circuits — Suited to circuits that require specified ripple-current performance at 120 Hz and at higher switching frequencies (50 kHz).
• General Purpose — Production Assemblies — Tray packing and snap-in termination support high-volume assembly and robust board retention.

Unique Advantages

• High-Voltage Capacitance in a Snap-In Form — Delivers 470 µF at 400 V in a snap-in radial can for applications needing secure mounting and high-voltage energy storage.
• Measured Low Dissipation — tanδ of 0.15 at 20°C/120 Hz reduces AC losses and helps maintain performance under ripple conditions.
• Dual-Frequency Ripple Handling — Rated ripple current specified at both 120 Hz and 50 kHz provides verified performance for line-frequency and high-frequency switching environments.
• Documented Endurance — 3000 hours at 85°C under rated conditions provides a clear endurance baseline for thermal and electrical stress planning.
• Production-Ready Packaging — Tray packing and mass production status simplify procurement and integration into volume manufacturing workflows.
• RoHS Compliance — Conforms to RoHS directives for use in compliant assemblies.
