LLS2G181MELA

The LLS2G181MELA is a snap‑in terminal aluminum electrolytic capacitor rated for 400 V with 180 µF capacitance. It is a polarized, radial can (snap‑in) device designed for general‑purpose power applications that require high‑voltage handling, substantial ripple current capability, and long endurance.

With a rated operating temperature range of −25°C to 85°C and a 3000‑hour endurance at 85°C under rated ripple conditions, this part is intended for applications where sustained high ripple duty and reliable performance over time are important.

Key Features

• Rated Voltage & Capacitance — 400 V nominal rating with 180 µF capacitance and ±20% tolerance, suitable for high‑voltage smoothing and energy storage in power circuits.
• Low Loss Tangent — Specified tanδ of 0.15 at 20°C and 120 Hz for this part, supporting lower dissipation under AC conditions (series data shows LLS series endurance characteristics).
• High Ripple Current Capability — 1.44 A at 120 Hz (low frequency) and 2.059 A at 50 kHz (high frequency) to handle substantial AC ripple in power supplies and filter networks.
• Leakage Current — Rated leakage current of 800 µA, specified after voltage application as part of the component’s electrical characteristics.
• Long Endurance — Endurance rating of 3000 hours at 85°C when subjected to DC bias plus rated ripple current, per LLS series specifications.
• Robust Mechanical Package — Snap‑in, radial can package (φ25 × 30 mm; L: 3 × D: 2.5 cm) for secure mechanical mounting and straightforward assembly.
• Polarized — Designed as a polarized electrolytic capacitor for DC filtering and energy storage applications.
• Regulatory Status — RoHS‑compliant.

Typical Applications

• General‑Purpose Power Electronics — Bulk smoothing and decoupling in 400 V circuits where high ripple current handling (1.44 A @120 Hz; 2.059 A @50 kHz) is required.
• Industrial Power Supplies — Long endurance (3000 h at 85°C) and RoHS compliance make this capacitor suitable for sustained operation in industrial power modules.
• Power Filtering and Energy Storage — Polarized 180 µF capacitance with ±20% tolerance provides reliable energy buffering in high‑voltage DC systems.

Unique Advantages

• High‑Voltage Capability: 400 V rating enables use in high‑voltage circuits without series stacking or complex topologies.
• Strong Ripple Performance: Clear low‑ and high‑frequency ripple current ratings support designs exposed to both mains‑frequency and switching ripple.
• Durability Under Load: 3000‑hour endurance at 85°C with rated ripple demonstrates sustained performance under continuous stress.
• Serviceable Snap‑In Mounting: Snap‑in radial can package provides robust board retention and ease of installation in power assemblies.
• Measured Electrical Characteristics: Leakage current and tanδ are specified for predictable design margining and thermal management.
• Production Availability: Listed as mass production status for consistent supply and deployment in production assemblies.
