LAQ2P471MELA40ZB

The LAQ2P471MELA40ZB from Nichicon is a snap-in terminal aluminum electrolytic capacitor in the LAQ series. It provides 470 µF capacitance at a 220 V rated voltage in a smaller-sized, radial can snap-in package designed for general-purpose applications.

Engineered for robust thermal and electrical performance, this part supports operation from −25 °C to +105 °C and is specified for endurance under rated D.C. bias plus ripple for 2000 hours at 105 °C, making it suitable where elevated temperature tolerance and reliable bulk capacitance are required.

Key Features

• Capacitance & Voltage — 470 µF nominal capacitance with a 220 V rated voltage and a tolerance of −20% to +20%.
• High-temperature rating — Rated for operation from −25 °C to +105 °C with specified permissible abnormal voltage at 105 °C.
• Endurance — Endurance specified as 2000 hours at 105 °C under D.C. bias plus rated ripple current; capacitance change within ±20% and leakage current ≤ initial specified value after test.
• Ripple current capability — Ripple current specified at 1.45 A (120 Hz) and 1.74 A (10 kHz), enabling smoothing and decoupling under realistic AC stress.
• Leakage current specification — Leakage current meets I ≤ 3√C μA after five minutes’ application of rated voltage at 20 °C (C = rated capacitance in µF).
• Polarized, snap-in mounting — Polarized aluminum electrolytic with snap-in terminals and radial can package for secure PCB assembly.
• Compact dimensions — Physical size L: 4 × D: 2.5 cm (smaller-sized variant in the LAQ series) with white-on-black sleeve marking for clear identification.
• Safety features — Pressure relief vent designed to operate under abnormal conditions without flame or dispersion of parts.

Typical Applications

• General Purpose — Intended for general-purpose electrical and electronic circuits that require bulk capacitance at 220 V and elevated operating temperatures.
• Power Supply Filtering — Suitable where a snap-in aluminum electrolytic capacitor is needed for filtering and smoothing at 220 V systems within the specified temperature range.
• Energy Storage — Applicable for general-purpose energy storage and decoupling roles in equipment operating up to 105 °C.

Unique Advantages

• 220 V, 470 µF capacity in a compact snap-in can — Delivers substantial bulk capacitance in a smaller-sized radial package for space-constrained designs.
• High-temperature endurance — Rated for 2000 hours at 105 °C under D.C. bias plus ripple, providing predictable performance in elevated-temperature environments.
• Measured ripple current ratings — Specified ripple current at both 120 Hz and 10 kHz supports designers assessing heating and lifetime under real operating conditions.
• Quantified leakage and tan δ limits — Leakage current and tan δ specifications (I ≤ 3√C μA; tan δ ≤ 0.20 at 120 Hz, 20 °C) allow precise loss and leakage budgeting in designs.
• Safety venting — Pressure relief venting reduces risk of dangerous failure modes by preventing flame or part dispersion during abnormal conditions.
• Clear identification — Printed white lettering on a black sleeve simplifies part recognition on populated assemblies.
