LASW6101MELA25ZB

The LASW6101MELA25ZB is a snap-in terminal aluminum electrolytic capacitor designed for high-voltage, general-purpose DC filtering in equipment exposed to voltage fluctuations. It is a smaller-sized, high-temperature (‑25°C to +105°C) capacitor optimized for applications that require durable ripple-current performance and enhanced safety under abnormal voltages.

Built to withstand extended operation at elevated temperature, this capacitor delivers 2000 hours of endurance under rated ripple current at 105°C and includes safety features to mitigate the effects of abnormally excessive voltage. The series is RoHS compliant.

Key Features

• Capacitance & Voltage: 100 µF nominal capacitance with a rated voltage of 420 V for high-voltage DC filtering and energy storage tasks.
• High-temperature Endurance: Qualified for operation from ‑25°C to +105°C and specified to withstand 2000 hours with rated ripple current at 105°C; after endurance, capacitance remains within ±20% of initial value.
• Ripple Current Capability: Rated ripple current of 690 mA at 120 Hz and 793.5 mA at 10 kHz, supporting sustained AC ripple handling in high-voltage supplies.
• Safety under Abnormal Voltage: Improved safety features including a pressure-relief vent and series test conditions for abnormal-voltage performance; for the 420 V series and capacitance range 100–220 µF the limited DC current test rating is 4 A (test voltages 520 VDC and 630 VDC).
• Package & Mounting: Radial can with snap-in terminals for secure PCB mounting in compact power assemblies and industrial equipment.
• Electrical Stability: Capacitance tolerance ±20% (at 120 Hz, 20°C), tan δ max 0.20 (120 Hz, 20°C), and leakage current specified per series (1 ≤ 3√(µA) after 5 minutes at rated voltage, 20°C).
• Environmental Compliance: Compliant with the RoHS directive (2011/65/EU,(EU)2015/863).

Typical Applications

• High‑voltage power supplies: Bulk DC filtering and energy smoothing where 420 V rating and elevated ripple capability are required.
• Industrial equipment exposed to voltage fluctuation: Reliable ripple handling and safety features make it suitable for machinery operating on unstable mains or variable DC sources.
• General-purpose DC filtering: Use in control panels and power conversion modules that need compact, high-voltage capacitors with robust temperature endurance.

Unique Advantages

• Extended high-temperature life: 2000-hour endurance at 105°C under rated ripple current supports longer field life in thermally demanding installations.
• High ripple tolerance at multiple frequencies: Specified ripple currents at 120 Hz and 10 kHz provide predictable performance across common switching and line frequencies.
• Enhanced abnormal-voltage protection: Pressure-relief vent design and series abnormal-voltage test ratings reduce risk in applications subject to overvoltage events.
• Space-efficient snap-in package: Smaller case sizes relative to the LAQ series allow denser board layouts without sacrificing ripple performance.
• Verified electrical stability: Tightly defined limits for capacitance change, tan δ, and leakage after endurance and shelf-life tests support reliable, repeatable designs.
• RoHS compliance: Meets applicable RoHS requirements for lead-free system integration and regulatory alignment.
