LLS2G151MELZ

The LLS2G151MELZ from Nichicon is a snap-in terminal aluminum electrolytic capacitor in the LLS series, designed for general-purpose power applications. It provides 150 µF capacitance at a 400 V rating in a radial, can-style snap-in package, packaged for tray handling and mass production.

Key attributes include a rated operating range to 85°C, a measured loss tangent (tanδ) of 0.15, and specified ripple current capability—features that support power supply smoothing, DC bus filtering and other high-voltage energy storage tasks in industrial and commercial equipment.

Key Features

• Capacitance & Voltage: 150 µF capacitance rated at 400 V for high-voltage filtering and energy storage duties.
• Tolerance & Polarization: ±20% capacitance tolerance and polarized construction for DC applications.
• Loss Characteristics: Specified tanδ of 0.15 (measurement at 120 Hz, 20°C as referenced in product description).
• Ripple Current Capability: Rated ripple currents of 1.24 A at 120 Hz and 1.773 A at 50 kHz to support continuous AC ripple on DC rails.
• Endurance & Reliability: Endurance proven to withstand 3000 hours of rated ripple current at 85°C per the LLS series specification.
• Mechanical & Mounting: Radial, can-style snap-in terminal mounting for secure board retention in through-hole assemblies; physical size approximately φ22 × 35 mm (L: 3.5 × D: 2.2 cm).
• Operating Environment: Rated for operation from −25 °C to +85 °C and supplied in tray packing for production handling.
• Compliance: RoHS compliant as stated in the product data.
• Leakage Current Specification: Leakage current defined by I ≤ 3√CV (µA) after 5 minutes at 20 °C, enabling predictable standby draw in DC systems.

Typical Applications

• Power supply smoothing: Bulk and smoothing capacitance on high-voltage DC rails where 400 V rating and 150 µF value are required.
• DC bus filtering: Energy buffering and ripple attenuation in power converters and industrial power supplies using snap-in mounting for robust through-hole assembly.
• Standby/backup energy storage: Local energy storage for UPS, standby circuits and power-hold functions that benefit from the capacitor’s rated endurance at 85 °C.

Unique Advantages

• High-voltage capability: 400 V rating enables direct use on elevated DC rails without additional series components.
• Designed for continuous ripple: Specified ripple current ratings at both low and higher frequencies (1.24 A at 120 Hz; 1.773 A at 50 kHz) support sustained AC ripple handling.
• Long rated life under load: Endurance specified as 3000 hours at 85 °C under rated ripple conditions, providing predictable service life planning.
• Production-ready packaging: Tray packing and snap-in terminals simplify assembly and handling for volume manufacturing.
• Predictable leakage behavior: Leakage current limit defined by I ≤ 3√CV (µA) for straightforward power-budget calculations.
• Regulatory alignment: RoHS compliance supports deployment in regions requiring restricted-substance conformance.
