LAQ2G121MELA30

The LAQ2G121MELA30 is an aluminum electrolytic capacitor from Nichicon's LAQ series engineered as a snap-in terminal, radial can package. It is a polarized, smaller-sized capacitor rated at 120 µF and 400 V, designed for general-purpose electronic applications that require high-voltage capability and elevated temperature tolerance.

With an operating range from -25°C to 105°C and a specified 2000-hour lifetime at 105°C, this part targets designs where compact footprint, robust thermal performance, and snap-in board mounting are important.

Key Features

• Capacitance & Tolerance: 120 µF nominal capacitance with ±20% tolerance at 120 Hz, 20°C.
• High Voltage Rating: 400 V rated voltage suitable for higher-voltage DC circuits within the LAQ series range.
• Temperature & Abnormal Voltage Handling: Operating temperature range of -25°C to 105°C and described as having "105°C permissible abnormal voltage" for enhanced thermal robustness.
• Snap-in Radial Package: Snap In mounting, radial can (snap-in) package for secure PCB retention and serviceable installation in power assemblies.
• Ripple Current Performance: Specified ripple current of 760 mA at 120 Hz and 874 mA at 10 kHz, supporting AC ripple handling across common power frequencies.
• Endurance & Lifetime: Rated for 2000 hours at 105°C under DC bias plus rated ripple current with post-test limits of ±20% capacitance change, tan δ within 200% of initial, and leakage current not exceeding initial specified values.
• Leakage & Loss Characteristics: Leakage current defined by I ≤ 3√C (µA) after 5 minutes at 20°C; tan δ ≤ 0.20 at 120 Hz, 20°C.
• Safety Feature: Pressure relief vent designed to operate under abnormal conditions without flames or dispersion of parts.
• Compact Dimensions: Smaller-sized footprint with dimensions approximately L: 3 × D: 2.5 cm for space-conscious designs.

Typical Applications

• General Purpose Electronics — Suited for a wide range of general-purpose circuits requiring a polarized aluminum electrolytic capacitor with a 400 V rating and 105°C temperature tolerance.
• Power Supply Assemblies — Applicable where high-voltage smoothing and ripple handling are needed in compact, snap-in mounted modules.
• Industrial Equipment — Appropriate for industrial systems that demand elevated temperature capability and durable snap-in mounting for secure PCB installation.

Unique Advantages

• High-voltage capability: 400 V rating enables use in higher-voltage DC circuits without requiring multiple lower-voltage parts in series.
• Elevated temperature endurance: Rated operation to 105°C and a 2000-hour lifetime at that temperature provide predictable in-field durability under thermal stress.
• Snap-in mounting reliability: Radial snap-in package simplifies PCB assembly and secures the capacitor for vibration-prone environments.
• Measured ripple specifications: Provided ripple current values at 120 Hz and 10 kHz allow designers to size this component with confidence for expected AC stress levels.
• Safety-conscious design: Pressure relief vent specification reduces the risk of hazardous failure modes under abnormal conditions.
• Compact form factor: Smaller-sized dimensions help reduce board area while preserving required capacitance and voltage performance.
