LLS2V221MELA

The LLS2V221MELA is an aluminum electrolytic, snap-in terminal capacitor designed for general-purpose power electronics applications. It combines a 350 V rated voltage with 220 µF capacitance in a compact snap-in can, intended for bulk energy storage and DC bus filtering where high voltage and robust ripple handling are required.

Key value propositions include rated operation to 350 V, endurance of 3000 hours at 85°C under rated ripple conditions, measurable low-loss performance (tan δ 0.15 at 20°C and 120 Hz), and RoHS compliance — all supplied in tray packing and available in mass production.

Key Features

• High Voltage Rating — 350 V rated voltage suitable for high-voltage DC bus and power-supply applications.
• Capacitance & Tolerance — 220 µF nominal capacitance with ±20% tolerance at 20°C and 120 Hz for predictable bulk energy storage and decoupling.
• Snap-In Radial Package — Snap-in terminal construction in a radial can (φ25 × 30 mm) for secure board mounting and high-current connections.
• Ripple Current Capability — Rated ripple current of 1.53 A at 120 Hz (low frequency) and 2.188 A at 50 kHz (high frequency) to support filtered and switching environments.
• Low Loss (tan δ) — tan δ = 0.15 (max) at 20°C and 120 Hz, indicating controlled dissipation under AC excitation.
• Endurance — Designed to withstand 3000 hours of rated ripple current at 85°C, with specified limits on capacitance change, tan δ, and leakage current after the test.
• Leakage Current — Typical leakage current specified at 830 µA, with datasheet criteria for maximum allowable leakage.
• Operating Temperature Range — Specified for −25°C to +85°C for stable performance across typical industrial ambient conditions.
• RoHS Compliant — Conforms to RoHS directive requirements.

Typical Applications

• Power Supply Filtering — Bulk capacitance and 350 V rating make this capacitor suitable for DC bus filtering and bulk energy storage in high-voltage power supplies.
• Inverter and Converter Circuits — High ripple current capability and endurance support smoothing and decoupling in inverter, converter, and motor-drive front ends.
• Industrial Power Electronics — Robust 3000-hour endurance at 85°C and low-loss characteristics serve industrial control and power-conditioning applications requiring long-term reliability.

Unique Advantages

• 350 V Rated Voltage: Enables direct use on high-voltage DC rails without additional voltage derating components.
• High Ripple Handling: 1.53 A (120 Hz) and 2.188 A (50 kHz) ripple ratings support both low- and high-frequency switching environments.
• Proven Endurance: 3000 hours at 85°C under rated ripple current provides predictable life characteristics for long-term designs.
• Low Dissipation (tan δ 0.15): Controlled loss at 120 Hz helps minimize heating under AC conditions and supports thermal planning.
• Compact Snap-In Form Factor: φ25 × 30 mm radial can with snap-in terminals simplifies PCB insertion and mechanical retention for high-current mounting.
• RoHS Compliance and Mass Production Availability: Environmentally compliant and available in tray packing for volume manufacturing.
