LASW6101MELZ30

The LASW6101MELZ30 is a 100 µF, 420 V polarized aluminum electrolytic capacitor in a snap‑in terminal (radial can) package from Nichicon’s LAS series. It is designed for general purpose power applications and equipment operating in environments with fluctuating voltages, offering a combination of high voltage rating, elevated temperature endurance and compact snap‑in mounting.

With a 105°C maximum operating temperature, a 2000‑hour endurance at 105°C under rated ripple conditions, and built‑in safety features for abnormal voltages, this capacitor provides reliable smoothing and energy buffering in demanding power circuits.

Key Features

• Capacitance & Voltage: 100 µF rated capacitance at 420 V DC with ±20% tolerance, suitable for high‑voltage smoothing and buffering tasks.
• High Temperature Endurance: Rated for operation from −25°C to +105°C and specified for 2000 hours at 105°C with DC bias plus rated ripple current applied.
• Snap‑in Radial Package: φ22 × 30L compact can with snap‑in terminals for secure chassis or board mounting and efficient mechanical retention.
• Ripple Current Performance: 690 mA at 120 Hz (low frequency) and 793.5 mA at 10 kHz (high frequency); frequency coefficient data supports increased rated ripple current at higher frequencies.
• Low Loss and Leakage: Maximum tan δ of 0.20 at 20°C and 120 Hz, and specified leakage current consistent with the series (example part leakage: 610 µA), supporting low dissipation and predictable performance.
• Safety Design: Improved safety features for abnormally excessive voltage and a pressure relief vent designed to operate without dangerous ignition or dispersal of parts under abnormal conditions.
• Environmental Compliance: RoHS compliant as specified for the LAS series.

Typical Applications

• Power Supply Filtering: Smoothing and bulk capacitance in AC‑DC and DC‑DC power supplies where high voltage and elevated temperature endurance are required.
• Industrial Power Equipment: Energy buffering and ripple handling in equipment exposed to voltage fluctuations and thermal stress.
• High‑Voltage DC Link Circuits: Support for DC link or intermediate bus applications that require 420 V capability and long‑term ripple endurance.

Unique Advantages

• Long Rated Life at Elevated Temperature: 2000 hours endurance at 105°C under rated ripple conditions, providing predictable aging and replacement planning.
• Robust Ripple Handling: Specified ripple current values at 120 Hz and 10 kHz with frequency coefficients that increase allowable ripple at higher frequencies, enabling reliable operation in varied converter topologies.
• Compact Snap‑in Form Factor: φ22 × 30L can with snap‑in terminals delivers space‑efficient installation and secure mechanical mounting.
• Designed for Voltage Fluctuations: Improved safety features and tested withstanding characteristics for applications in environments with unstable supply conditions.
• Low Dissipation and Controlled Leakage: tan δ ≤ 0.20 at 20°C/120 Hz and controlled leakage current, supporting efficient power circuits with manageable losses.
• RoHS Compliant: Suitable for designs requiring restriction of hazardous substances compliance.
