LLS2W221MELC

The LLS2W221MELC is a snap-in terminal aluminum electrolytic capacitor rated at 450 V with a nominal capacitance of 220 µF. Designed for general-purpose power applications, it delivers high-voltage energy storage in a radial, snap-in can package (φ35 × 25 mm).

Key value comes from its combination of high voltage rating, defined ripple-handling capability at low and high frequencies, and a 3000-hour endurance at 85°C—making it suitable for demanding power-filtering and bulk-energy tasks in industrial electronics and power systems.

Key Features

• Capacitance & Voltage — 220 µF nominal capacitance at a rated voltage of 450 V for high-voltage bulk storage and filtering.
• Tolerance — ±20% capacitance tolerance at 120 Hz, 20°C for predictable sizing in design calculations.
• Snap-in Radial Can Package — φ35 × 25 mm radial, snap-in construction for secure board mounting and high-current power assemblies.
• Ripple Current Capability — Low-frequency ripple current of 1.590 A at 120 Hz and high-frequency ripple current of 2.2737 A at 50 kHz to support both mains-frequency and higher-frequency switching environments.
• Leakage Current — Specified leakage current of 940 µA to aid in static-loss and bias planning.
• Loss Tangent (tan δ) — tan δ = 0.20 at 20°C and 120 Hz, providing a defined dissipation characteristic for thermal budgeting.
• Endurance — Rated for 3000 hours at 85°C under DC bias plus rated ripple current for long-term reliability in thermal-stressed installations.
• Operating Temperature Range — Specified for −25°C to +85°C to match a broad set of industrial operating conditions.
• RoHS Compliant — Conforms to RoHS requirements for restricted substances.

Typical Applications

• Industrial Power Supplies — Bulk smoothing and energy storage where 450 V rating and high ripple capability are required.
• Power Conversion & Inverters — DC-link and filtering roles in converters and inverter systems operating at elevated voltages.
• Uninterruptible Power Supplies (UPS) — Energy buffering and ripple attenuation in high-voltage UPS stages.
• Large-Capacity Filter Banks — Parallel capacitor assemblies for high-voltage filtering and decoupling in power electronics racks.

Unique Advantages

• High-voltage capability: 450 V rating enables use in elevated-voltage power stages without series stacking.
• Defined ripple performance: Specified ripple currents at 120 Hz and 50 kHz allow accurate thermal and lifetime budgeting for both mains-frequency and switching-power environments.
• Long endurance at temperature: 3000 hours at 85°C under rated ripple current supports predictable lifecycle planning for industrial applications.
• Compact snap-in form factor: φ35 × 25 mm radial can with snap-in terminals simplifies installation in high-current assemblies while conserving board area.
• Measured dissipation and leakage specs: tan δ = 0.20 and 940 µA leakage provide quantifiable values for loss and standby calculations.
• RoHS compliance: Meets RoHS directive requirements for restricted substances.
