LASW6151MELA35

The LASW6151MELA35 is a snap-in terminal aluminum electrolytic capacitor from Nichicon’s LAS series. It provides 150 µF capacitance at a 420 V rating in a compact can-style snap-in package suited for general-purpose power applications.

Designed for sustained operation up to 105°C, this part targets power-supply filtering and equipment exposed to voltage fluctuations, delivering defined ripple-current capability and extended endurance for reliable operation in demanding thermal and electrical environments.

Key Features

• Electrical Performance — 150 µF capacitance with tolerance of −20% to +20% and tanδ (DF) of 0.20 maximum, measured at 20°C, 120 Hz.
• High Voltage Rating — Rated voltage 420 V suitable for high-voltage DC applications where elevated working voltage is required.
• Ripple Current Capability — Low-frequency ripple current 820 mA (120 Hz) and high-frequency ripple current 943 mA (10 kHz), enabling effective smoothing across a range of switching frequencies.
• Thermal Endurance — Rated for operation from −25°C to +105°C with an endurance life of 2000 hours at 105°C under rated ripple and DC bias conditions.
• Leakage and Reliability — Leakage current specified at 750 µA; designed with safety features including a pressure relief vent and improved resistance to abnormal voltage conditions.
• Package & Mounting — Snap-in radial can package, size φ25 × 35L (D: 2.5 cm × L: 3.5 cm), supplied in tray packing for straightforward assembly.
• Environmental Compliance — RoHS compliant.

Typical Applications

• General-Purpose Power Supplies — Bulk smoothing and filtering in high-voltage power supplies where 420 V rating and defined ripple capability are required.
• Equipment in Voltage-Fluctuating Environments — Suited for systems subject to varying supply conditions thanks to enhanced safety features and 105°C endurance.
• High-Voltage Industrial Electronics — Used in assemblies that require polarized high-voltage capacitance with robust ripple handling over a range of frequencies.

Unique Advantages

• High ripple current for size — Provides 820 mA (120 Hz) and 943 mA (10 kHz) ripple capability in a compact φ25 × 35L can, enabling smaller designs without sacrificing performance.
• 105°C, 2000-hour endurance — Long-duration endurance rating at elevated temperature supports sustained operation under heavy electrical stress.
• Improved safety under abnormal voltage — Series-level safety enhancements and a pressure relief vent reduce risk in applications exposed to excessive voltage events.
• Snap-in radial package — Snap-in terminals simplify placement and mechanical retention in power assemblies, supplied in tray packing for production use.
• RoHS compliant — Meets environmental regulation for lead-free manufacturing processes.
