LLS1J103MELB

The LLS1J103MELB is an aluminum electrolytic capacitor in Nichicon's LLS series, featuring a snap-in terminal radial can design and a standard 85°C temperature rating. It provides 10,000 µF of polarized capacitance at a 63 V rating, intended for general-purpose applications that require bulk capacitance and secure board-level mounting.

Designed and manufactured by Nichicon, this part delivers long-term endurance and measurable ripple-current capability for assemblies that operate within a −40°C to +85°C temperature range.

Key Features

• Capacitance & Voltage: 10,000 µF nominal capacitance with a 63 V rated voltage and ±20% tolerance, providing substantial bulk energy storage in a single component.
• Snap-In Radial Can Package: Snap-in terminal type with a radial, can-style package (φ30 × 50L; size listed as L: 5 × D: 3 cm), optimized for secure, mechanical board mounting.
• Operating Temperature: Rated for −40°C to +85°C operation, suitable for assemblies that operate across standard commercial temperature ranges.
• Endurance: Specified to withstand 3,000 hours at 85°C when subjected to D.C. bias plus rated ripple current; capacitance change remains within ±20% after endurance testing per the series specification.
• Ripple Current Capability: Rated ripple current of 5.78 A at 120 Hz and 6.647 A at 50 kHz, enabling the capacitor to handle significant AC ripple within its rated conditions.
• Leakage and Loss Characteristics: Leakage current conforms to the datasheet formula (I ≤ 3√CV μA after 5 minutes at 20°C) and tan δ for the 63 V rating is specified (maximum 0.25 at 120 Hz, 20°C).
• Compliance: RoHS compliant in accordance with the directive noted for the LLS series.
• Packaging: Tray packing suitable for mass production and assembly environments.

Typical Applications

• General-purpose assemblies: Provides bulk capacitance where polarized aluminum electrolytic capacitors are required in board-level designs.
• Power-related modules: Used in circuits that need large capacitance and rated 63 V voltage handling for energy reserve and smoothing duties.
• Panel and rack-mounted equipment: Snap-in terminals support secure mounting in assemblies that require mechanical robustness and straightforward insertion.

Unique Advantages

• High bulk capacitance in a single package: 10,000 µF nominal value reduces the number of components needed for energy storage or decoupling.
• Snap-in mounting for secure assembly: Snap-in radial can construction simplifies insertion and provides robust mechanical retention on the board.
• Documented endurance at operating limit: Rated for 3,000 hours at 85°C under rated ripple and DC bias, providing predictable long-term behaviour.
• Measurable ripple acceptance: Published ripple-current ratings at both low and higher frequencies (120 Hz and 50 kHz) let designers size thermal and cooling requirements more accurately.
• Clear electrical limits and test criteria: Leakage current, tan δ, and post-endurance capacitance limits are specified in the series datasheet for verification and qualification.
• RoHS compliance: Meets the RoHS directive requirements noted for the LLS series, supporting regulatory needs for many markets.
