LAQ2G470MELZ25

The LAQ2G470MELZ25 is a snap-in terminal aluminum electrolytic capacitor from Nichicon’s LAQ series. It delivers 47 µF capacitance at a 400 V rated voltage in a smaller-sized snap-in, radial can package designed for general-purpose use.

Designed for operation from -25 °C to 105 °C with a specified 2000‑hour endurance at 105 °C and permissible abnormal voltage handling, this part targets applications that require a compact, high-voltage electrolytic solution with verified ripple performance and polarized installation.

Key Features

• Capacitance & Voltage — 47 µF rated capacitance at 400 V, with tolerance −20% to +20%.
• High-temperature endurance — Rated for operation from −25 °C to +105 °C and specified 2000 hours endurance at 105 °C under DC bias plus rated ripple current.
• Snap-in radial can package — Snap-in mounting type in a radial, can-style package for secure PCB installation and mechanical stability.
• Smaller-sized footprint — Compact physical dimensions (L: 2.5 cm × D: 2.2 cm) suitable where board space is constrained.
• Ripple current performance — Rated ripple current of 350 mA at 120 Hz and 402.5 mA at 100 kHz, specified for the part under its rated conditions.
• Polarized design — Polar capacitor construction for correct orientation in DC circuits.
• Safety feature — Pressure relief vent performance specified in the series datasheet to operate without dangerous outcomes under abnormal conditions.

Typical Applications

• General-purpose industrial and commercial equipment — For circuits requiring a 47 µF, 400 V snap-in electrolytic with extended temperature and endurance characteristics.
• High-voltage DC assemblies — Fits designs that specify a 400 V polarized aluminum electrolytic in a compact snap-in can.
• Board-level power modules — Where a smaller-sized radial snap-in capacitor is needed to meet size and ripple requirements.

Unique Advantages

• Compact 400 V solution: 47 µF capacitance in a smaller-sized snap-in can (L: 2.5 cm × D: 2.2 cm) minimizes PCB footprint for high-voltage designs.
• High-temperature reliability: Rated for operation to 105 °C with a 2000‑hour endurance specification at that temperature, supporting long-term performance under thermal stress.
• Verified ripple capability: Specified ripple currents at both low (120 Hz) and high (100 kHz) frequencies help designers match the capacitor to expected operating conditions.
• Robust safety behavior: Pressure relief venting behavior is defined to avoid flames or dispersion under abnormal conditions, as detailed in the series documentation.
• Polarized snap-in convenience: Snap-in terminals provide a secure mechanical connection for PCB-mounted high-voltage capacitors and simplify assembly.
