LASW6331MELB45ZB

The LASW6331MELB45ZB is a Nichicon LAS series aluminum electrolytic capacitor in a snap‑in terminal (radial can) package, rated at 330 µF and 420 V. It is a general-purpose, high-voltage solution designed for applications that require stable capacitance and sustained ripple endurance in environments with voltage fluctuation.

Key value comes from its 105°C permissible operating temperature, 2000‑hour endurance at 105°C under rated ripple conditions, compact φ30 × 45 mm case, and enhanced safety features for abnormal voltage events.

Key Features

• Capacitance & Voltage — 330 µF nominal capacitance with a 420 V rated voltage for high‑voltage DC applications.
• Temperature Range & Endurance — Rated for −25°C to +105°C with an endurance test of 2000 hours at 105°C under D.C. bias plus rated ripple current.
• Mounting & Package — Snap‑in terminal, radial can (φ30 × 45 mm) for secure board/chassis mounting and mass production tray packing.
• Tolerance & Polarization — Capacitance tolerance of ±20% (measured at 120 Hz, 20°C); polarized device.
• Ripple Current Performance — Rated ripple current: 1.2 A at 120 Hz (low frequency) and 1.38 A at 100 kHz (high frequency); frequency coefficient available for adjusting ripple rating across frequency.
• Safety Design — Improved safety features for abnormally excessive voltage and a pressure relief vent that operates without dangerous conditions (no flames, ignition, or dispersion of pieces).
• Regulatory — RoHS compliant as specified in the product information.

Typical Applications

• General-purpose industrial equipment — Provides bulk energy storage and filtering where designers require a 420 V electrolytic capacitor with extended high‑temperature endurance.
• Equipment operating in voltage‑fluctuating environments — Series features and safety performance are suited for systems exposed to varying line conditions.
• High-temperature assemblies — Rated operation to 105°C and a 2000 h endurance rating make it appropriate for assemblies that run hot or are subjected to sustained thermal stress.

Unique Advantages

• Long ripple endurance: Endurance of 2000 hours at 105°C with rated ripple current applied reduces replacement frequency in demanding installations.
• Compact snap‑in form factor: φ30 × 45 mm radial can with snap‑in terminals supports reliable mounting and efficient mass production handling.
• Designed for abnormal voltage conditions: Enhanced safety features and a pressure relief vent improve operational safety under excessive voltage events.
• Frequency‑aware ripple rating: Frequency coefficient data (e.g., 0.88 at 50 Hz up to 1.15 at ≥10 kHz) lets engineers scale ripple expectations by operating frequency.
• Wide operating temperature: −25°C to +105°C rating supports use in elevated temperature environments.
• RoHS compliant: Meets RoHS directive requirements noted in the product documentation.
