LAS2G121MELA25ZB

The LAS2G121MELA25ZB is a snap-in terminal aluminum electrolytic capacitor offering 120 µF capacitance at a 400 V rated voltage. Designed as a radial can (snap-in) with a bottom plate (ZB code) in a compact φ25 × 25L package, it targets general-purpose power applications that require high-voltage bulk capacitance and robust thermal endurance.

Key value propositions include operation to 105 °C with a rated lifetime of 2000 hours at that temperature, substantial rated ripple current, and built-in safety features for abnormal overvoltage conditions. The part is RoHS compliant.

Key Features

• Electrical Performance — 120 µF nominal capacitance with ±20% tolerance and a 400 V rated voltage for high-voltage bulk energy storage.
• High-Temperature Endurance — Rated for operation from −25 °C to +105 °C with a specified lifetime of 2000 hours at 105 °C under D.C. bias plus rated ripple current.
• Ripple Current Capability — Rated ripple current of 760 mA at 120 Hz and 874 mA at 10 kHz; frequency coefficient of rated ripple current increases at higher frequencies (up to 1.15 at 10 kHz or more as defined in the series data).
• Snap-In Mounting — Radial, can-type snap-in terminals with bottom plate (ZB code) for secure chassis or PCB mounting and simplified assembly.
• Compact Package — φ25 × 25L size (25 mm diameter × 25 mm length) for space-conscious power designs.
• Safety Features — Pressure relief vent designed to operate under abnormal conditions to prevent dangerous outcomes during excessive voltage events.
• Regulatory Compliance — Compliant with RoHS directive (2011/65/EU,(EU)2015/863).

Typical Applications

• General‑purpose circuits — Provides bulk capacitance and smoothing in circuits requiring a 400 V rated capacitor with snap-in mounting.
• Power modules and power supplies — Used where 120 µF at high voltage and elevated operating temperatures (up to 105 °C) are required.
• Chassis- or PCB-mounted assemblies — Snap-in radial can with bottom plate for reliable mechanical installation and electrical decoupling.

Unique Advantages

• High thermal endurance: 2000 hours rated life at 105 °C supports designs that operate at elevated temperatures without rapid degradation.
• Robust ripple handling: Specified ripple current at 120 Hz and 10 kHz plus a positive frequency coefficient allow predictable performance across common ripple frequencies.
• Compact, secure mounting: φ25 × 25L snap-in package with bottom plate enables compact layout and reliable mechanical attachment.
• Built-in safety venting: Pressure relief vent operates under abnormal overvoltage to reduce risk of hazardous failure modes.
• RoHS compliant: Meets regulatory requirements for restricted substances for broader market acceptance.
• Series‑level improvements: Designed for smaller case sizes and higher ripple current compared with earlier series, per series documentation.
