LAQ2G271MELB40ZB

The LAQ2G271MELB40ZB is an aluminum electrolytic capacitor in a snap-in radial can package, polarized and designed for general-purpose use. It delivers 270 µF of capacitance at a 400 V rated voltage in a smaller-sized form factor.

Engineered for applications that require elevated temperature tolerance and controlled endurance, this part supports operation from -25°C to +105°C and includes design elements for permissible abnormal voltage conditions and pressure-relief safety performance.

Key Features

• Capacitance & Voltage — 270 µF nominal capacitance with a 400 V rated voltage, suited for higher-voltage circuits requiring bulk capacitance.
• High Temperature Rating — Rated for operation from -25°C to +105°C with endurance specified for 2000 hours at 105°C under rated DC bias plus rated ripple current.
• Permissible Abnormal Voltage — Designed to accommodate abnormal voltage conditions as specified in the LAQ series description.
• Snap-in Radial Can Package — Snap In mounting style with a radial can package for secure chassis or PCB installation and mechanical stability.
• Ripple Current Performance — Ripple current ratings of 1.3 A at 120 Hz and 1.495 A at 10 kHz, supporting AC ripple handling at both low and higher frequencies.
• Leakage Current Specification — Leakage current defined as I ≤ 3√C µA after 5 minutes’ application of rated voltage at 20°C (C = rated capacitance in µF).
• Tolerance and Polarization — Capacitance tolerance of ±20% at 120 Hz, 20°C; polarized construction.
• Compact Size — Smaller-sized footprint with dimensions listed as L: 4 × D: 3 cm for space-conscious designs.
• Safety Performance — Pressure relief vent designed to operate without producing flames, ignition, or dispersion of parts under the specified test conditions.

Typical Applications

• General Purpose — A polarized aluminum electrolytic capacitor intended for a wide range of general-purpose circuits requiring 270 µF at 400 V and operation up to 105°C.
• High-Voltage Bulk Capacitance — Used where higher DC voltages and substantial capacitance are required within a smaller package footprint.
• Temperature-Challenged Environments — Suitable for designs that must maintain performance across -25°C to +105°C ambient ranges with specified endurance at high temperature.

Unique Advantages

• High Voltage Capability: 400 V rated voltage enables use in higher-voltage circuits without additional series stacking.
• Elevated Temperature Endurance: Specified 2000 hours at 105°C under rated conditions provides a defined lifetime metric for thermal reliability planning.
• Defined Leakage Limits: Leakage current is specified by a clear formula (I ≤ 3√C µA after 5 minutes at 20°C), allowing predictable standby losses in designs.
• Frequency-Dependent Ripple Ratings: Ripple current specs at both 120 Hz and 10 kHz support designers addressing ripple at different operating frequencies.
• Safety-Designed Venting: Pressure relief vent operation is specified to avoid flames, ignition, or dispersion, supporting safer failure modes.
• Snap-in Mechanical Convenience: Snap In mounting in a radial can simplifies installation for applications requiring secure mechanical retention.
