Overview of LLS1E183MELB – Snap-In Aluminum Electrolytic Capacitor, 25 V · 18,000 µF
The LLS1E183MELB is an aluminum electrolytic, snap-in terminal capacitor designed for general-purpose power applications. It delivers high capacitance (18,000 µF) at a 25 V rating with polarized construction and snap-in mounting for robust mechanical retention.
Engineered for sustained ripple loading, the device offers specified low- and high-frequency ripple current capability and a 3,000-hour endurance at 85°C, making it suitable for designs that require bulk energy storage and extended operational reliability within its rated temperature range.
Key Features
- Capacitance and Voltage: 18,000 µF nominal capacitance with a 25 V rated voltage and ±20% tolerance (120 Hz, 20°C), providing substantial bulk storage for DC circuits.
- High Ripple-Current Capability: Rated ripple current of 4.66 A at 120 Hz and 5.359 A at 50 kHz, enabling sustained ripple handling across low and high frequency conditions.
- Endurance and Reliability: Endurance rating of 3,000 hours at 85°C under rated ripple current; designed to meet the listed endurance specifications after restoration to 20°C.
- Loss Angle (tan δ): tan δ (DF) specified at 0.40 (measured at 20°C, 120 Hz) for the 25 V rating, supporting predictable dissipation characteristics.
- Leakage Current: Specified leakage current of 2,010 µA (measured after applied rated voltage), with the datasheet listing the general leakage-current criterion for verification.
- Packaging and Mounting: Snap-in radial can package for secure board mounting; supplied in tray packing for handling and assembly.
- Operating Range and Compliance: Rated for –40°C to +85°C operation and RoHS compliant; manufactured for mass production availability.
Typical Applications
- General-purpose power systems: Bulk capacitance and ripple handling for power rails and DC energy storage where large capacitance and sustained ripple capability are required.
- Industrial electronics: Use in equipment that requires extended endurance at elevated temperatures, supported by the 3,000-hour rating at 85°C.
- Power assemblies with snap-in mounting: Designs that benefit from radial snap-in terminals for secure mechanical attachment and straightforward board layout.
Unique Advantages
- Large-capacitance solution: 18,000 µF nominal value reduces the number of parallel components needed for bulk storage and smoothing.
- Robust ripple performance: Defined ripple-current ratings at both 120 Hz and 50 kHz help ensure predictable thermal and electrical behaviour under AC loading.
- Long endurance at elevated temperature: 3,000-hour life at 85°C supports extended service in higher-temperature operating environments.
- Snap-in radial package: Mechanical stability and efficient board mounting for applications requiring reliable retention and assembly throughput.
- Regulatory compliance: RoHS-compliant construction for regulatory alignment in global product deployments.
- Production-ready supply: Part is in mass production and packaged in trays to support volume assembly and inventory planning.
