LASW6221MELB35ZB

The LASW6221MELB35ZB is a Nichicon LAS series snap‑in aluminum electrolytic capacitor designed for high‑voltage, general‑purpose power applications. It provides 220 µF capacitance at a 420 V rating in a compact snap‑in can (φ30 × 35 mm) with tray packing for production handling.

Engineered for robust operation at elevated temperature, this part offers 105 °C endurance (2000 hours), enhanced safety features for abnormal overvoltage conditions, and RoHS compliance—making it suitable where sustained ripple tolerance and reliability under voltage fluctuation are required.

Key Features

• Electrical Performance: 220 µF capacitance with tolerance ±20% measured at 20 °C, 120 Hz; rated voltage 420 V; polar configuration for DC power circuits.
• Loss & Leakage Characteristics: Tangent of loss angle (tan δ) ≤ 0.20 (20 °C, 120 Hz); leakage current specified at 910 µA.
• Ripple Current & Frequency Response: Low‑frequency ripple current 1.00 A (120 Hz) and high‑frequency ripple current 1.15 A (100 kHz). Frequency coefficient of rated ripple current increases up to 1.15 at 10 kHz or higher per LAS series data.
• High‑Temperature Endurance: Rated for continuous operation up to 105 °C with a life/endurance specification of 2000 hours under rated ripple and D.C. bias conditions.
• Safety Features: Snap‑in large‑can construction with a pressure relief vent designed to operate under abnormal voltage without hazardous conditions; improved safety provisions noted for excessive voltage events.
• Mechanical & Packaging: Radial, snap‑in can sized φ30 × 35 mm (L: 3.5 × D: 3.0 cm); supplied in tray packing for automated handling and assembly. Status: Mass Production.
• Environmental Compliance: RoHS compliant (per LAS series declarations).

Typical Applications

• General‑Purpose Power Supplies: Bulk filtering and smoothing in high‑voltage DC power rails where 420 V ratings and reliable ripple handling are required.
• Equipment Exposed to Voltage Fluctuations: Designed for systems operating in environments with variable or fluctuating supply voltages, leveraging the LAS series’ improved safety against abnormal voltage.
• High‑Ripple Circuits: Suitable for circuits with significant ripple currents thanks to specified ripple ratings at both low and high frequencies and the series’ frequency coefficient characteristics.
• Industrial and Commercial Power Modules: Uses include energy storage and smoothing in industrial control systems and commercial power conversion equipment requiring 105 °C endurance.

Unique Advantages

• High‑Voltage Capability: 420 V rating supports higher DC bus voltages without series stacking, simplifying design.
• Proven 105 °C Endurance: 2000 hours endurance at 105 °C under rated ripple and bias, providing predictable lifetime behavior in elevated‑temperature applications.
• Dual‑Frequency Ripple Performance: Specified ripple current at 120 Hz and 100 kHz with a supporting frequency coefficient allows designers to size capacitors for both low‑ and high‑frequency stress.
• Compact Snap‑In Form Factor: φ30 × 35 mm radial snap‑in can balances compact footprint with robust terminal retention for secure PCB mounting in power assemblies.
• Enhanced Safety Design: Pressure relief vent and LAS series safety improvements mitigate hazardous outcomes during abnormal overvoltage events.
• Production‑Ready Packaging: Tray packing and mass‑production availability support volume assembly and procurement planning.
