LLS2E221MELY

The LLS2E221MELY is an aluminum electrolytic snap‑in terminal capacitor rated at 250 V and 220 µF, designed for general‑purpose power applications. It combines a compact radial can snap‑in package with performance characteristics targeted at bulk filtering and energy storage in power electronics.

Key value propositions include high ripple current capability at both low and high frequencies, extended endurance tested to 3000 hours at 85°C, and RoHS compliance—making it suitable for production environments requiring reliable, long‑life capacitors.

Key Features

• Rated Capacitance & Voltage — 220 µF nominal capacitance with a 250 V rated voltage and ±20% tolerance, providing bulk energy storage for high‑voltage circuits.
• High Ripple Current — Supports 1.26 A ripple at 120 Hz (low frequency) and 1.89 A at 50 kHz (high frequency), enabling effective smoothing in supplies operating across a range of switching frequencies.
• Endurance & Reliability — Specified for 3000 hours of endurance at 85°C under rated ripple conditions; capacitance, tan δ, and leakage are defined for recovery to 20°C after endurance testing.
• Loss Angle (tan δ) — tan δ of 0.15 (max) measured at 20°C and 120 Hz for the 250 V rating, indicating controlled dissipation for stable performance.
• Leakage Current — 700 µA specified leakage current, suitable for general‑purpose power designs requiring defined leakage behavior.
• Package & Mounting — Radial, can snap‑in construction (φ20 × 25 mm L) for secure snap‑in board mounting and straightforward installation in power assemblies.
• Operating Range & Compliance — Operating temperature range −40°C to +85°C and RoHS compliant; the part is available in mass production and tray packed for manufacturing workflows.
• Polarized Design — Polarized capacitor intended for DC applications where polarity is observed.

Typical Applications

• General‑purpose power filtering — Bulk smoothing and decoupling in high‑voltage DC circuits where 250 V rating and 220 µF capacitance are required.
• Power conversion and supply rails — Energy storage and ripple suppression in power supplies and converters operating within the specified temperature and ripple limits.
• Industrial electronics — Use in general industrial power assemblies that require robust endurance (3000 h at 85°C) and snap‑in mounting for secure PCB installation.

Unique Advantages

• High voltage capability: 250 V rating enables use in higher‑voltage DC circuits while maintaining a compact form factor.
• Dual‑frequency ripple performance: Rated ripple currents specified at 120 Hz and 50 kHz support both legacy transformer‑rectified supplies and modern switching converters.
• Proven endurance: 3000 hours at 85°C under rated ripple conditions provides a defined reliability baseline for long‑life designs.
• Compact snap‑in package: φ20 × 25 mm radial can with snap‑in terminals simplifies PCB retention and mechanical stability in assemblies.
• Production ready: Mass production status and tray packing support volume procurement and automated handling.
• RoHS compliant: Meets RoHS requirements for lead‑free manufacturing processes.
