LASW6331MELC35

The LASW6331MELC35 is a snap-in terminal aluminum electrolytic capacitor rated 330 µF at 420 V with a φ35×35L package. Designed for general-purpose use, it targets equipment operating in voltage-fluctuating environments where high ripple handling and thermal endurance are required.

Key value comes from its 105°C permissible operating range with a 2000-hour endurance at 105°C, robust ripple-current capability, and safety features intended to mitigate abnormal overvoltage conditions while remaining RoHS compliant.

Key Features

• Electrical Performance — 330 µF nominal capacitance at 420 V with ±20% tolerance (measured at 120 Hz, 20°C). Tangent of loss angle (tan δ) is 0.20 max at 120 Hz, 20°C.
• Leakage and Loss — Specified leakage current of 1.11 mA and controlled dissipation (tan δ) for predictable loss behavior in high-voltage circuits.
• High Ripple Capability — Rated ripple current 1.2 A at 120 Hz, 105°C and 1.38 A at 10 kHz, supporting applications with significant AC components on DC rails.
• Wide Thermal Endurance — Operating temperature range −25°C to +105°C with a rated endurance of 2000 hours at 105°C; post-endurance limits are specified for capacitance, tan δ and leakage current.
• Snap-In Mechanical Packaging — Radial, can-type snap-in terminal construction for secure PCB or chassis mounting; compact footprint with dimensions of 3.5 × 3.5 cm (φ35×35L).
• Safety and Compliance — Improved safety features for abnormally excessive voltage and a pressure-relief vent designed to operate without flames or dispersion; RoHS compliant.
• Frequency Characterization — Frequency coefficient data provided for ripple-current scaling across 50 Hz to ≥10 kHz operation.

Typical Applications

• Voltage‑fluctuating equipment — Specified by the series as well suited for equipment operating where supply voltage varies, leveraging its safety features and 105°C endurance.
• High‑ripple environments — Used where substantial ripple current is present thanks to rated ripple currents of 1.2 A (120 Hz) and 1.38 A (10 kHz).
• General‑purpose industrial and commercial equipment — Applies to designs that require a polarized, high-voltage electrolytic capacitor with compact snap-in packaging and RoHS compliance.

Unique Advantages

• Validated high-temperature endurance: 2000 hours at 105°C provides documented longevity under elevated operating temperatures.
• High-voltage, high-capacitance option: 420 V rating combined with 330 µF nominal capacitance supports energy storage and DC-side requirements in higher-voltage designs.
• Robust ripple handling: Rated ripple currents at both low (120 Hz) and high (10 kHz) frequencies let designers size capacitors confidently for real-world AC components on DC rails.
• Snap-in mounting for secure installation: Radial snap-in terminals simplify mechanical retention for PCB or chassis assemblies where vibration or mechanical stress is a consideration.
• Built-in safety considerations: Enhanced safety features and a pressure-relief vent reduce the risk of hazardous failures under abnormal voltage conditions.
• Regulatory compliance: RoHS compliance supports use in applications requiring restricted-substance conformance.
