LLS1E153MELZ

The LLS1E153MELZ is a snap‑in terminal aluminum electrolytic capacitor from Nichicon's LLS series designed for general purpose power applications. It provides high bulk capacitance (15 000 µF) at a 25 V rating in a compact φ22 × 50 mm can with snap‑in mounting.

Engineered for sustained ripple handling and long endurance, this capacitor is specified for operation from −40 °C to +85 °C with a guaranteed 3 000‑hour life at 85 °C, making it suited to designs that require high energy storage and continuous ripple current capability.

Key Features

• Capacitance and Voltage: 15 000 µF nominal capacitance at a 25 V rated voltage with ±20% tolerance, providing significant bulk energy storage for power rails and smoothing.
• High Ripple Handling: Rated for 4.21 A ripple current at 120 Hz (low frequency) and 4.841 A at 50 kHz (high frequency), enabling continuous operation under substantial AC stress.
• Endurance and Reliability: Withstands 3 000 hours of rated ripple current at 85 °C as specified in the LLS series endurance data, with leakage current and dissipation factor maintained within specified limits after the endurance test.
• Loss Characteristics: Tangent of loss angle (tan δ) specified at 0.4 (max.) for the 25 V rating measured at 20 °C, 120 Hz, providing defined dissipation characteristics for thermal and AC loss calculations.
• Leakage Current: Specified leakage current value of 1 830 µA (product data), useful for standby and off‑load current budgeting.
• Package and Mounting: Radial can with snap‑in terminals (snap‑in mounting) in a φ22 × 50 mm package; supplied in tray packing for production assembly.
• Environmental & Compliance: RoHS compliant and produced for mass production availability.

Typical Applications

• General Purpose Power Filtering: Bulk capacitance and rated ripple current make this capacitor suitable where large energy buffering and smoothing are required in general purpose circuits.
• DC Link and Energy Storage: High capacitance at 25 V supports DC bus stabilization and short‑term energy support within the stated temperature and endurance limits.
• Continuous Ripple Environments: Designed for applications that require sustained ripple handling over long operating periods at elevated temperatures (3 000 hours at 85 °C).

Unique Advantages

• High Bulk Capacitance: 15 000 µF provides substantial stored energy in a compact φ22 × 50 mm package, reducing the need for multiple smaller capacitors.
• Defined Ripple Performance: Explicit low‑ and high‑frequency ripple current ratings (4.21 A at 120 Hz; 4.841 A at 50 kHz) let engineers size components against real operating conditions.
• Long Endurance at Elevated Temperature: Specified 3 000‑hour life at 85 °C under rated ripple conditions supports continuous operation in demanding thermal environments.
• Snap‑in Mounting for Secure Installation: Snap‑in terminal configuration provides a robust mechanical and electrical connection for high‑current power assemblies.
• Traceable Performance Specs: Clear tan δ and leakage current values support thermal and leakage budgeting in power designs.
• Production‑Ready Packaging: Tray packing and mass production status facilitate volume procurement and assembly planning.
