LAQ2G181MELC25ZB

The LAQ2G181MELC25ZB is an aluminum electrolytic capacitor from Nichicon’s LAQ series. It is a snap‑in terminal, radial can type with 180 µF capacitance and a 400 V rated voltage, provided in tray packing for mass production.

Engineered for general‑purpose applications, this component combines a 105°C category temperature range with documented endurance and ripple current capability to support high‑voltage power circuitry where a polarized, high‑capacitance snap‑in solution is required.

Key Features

• Electrical Performance — 180 µF nominal capacitance with ±20% tolerance and a 400 V rated voltage for high‑voltage circuit applications.
• Thermal Range & Endurance — Rated for operation from -25°C to +105°C with an endurance specification of 2000 hours at 105°C under D.C. bias plus rated ripple current.
• Ripple Current Capability — Specified ripple current of 950 mA at 120 Hz and 1.093 A at 10 kHz for AC filtering and smoothing under realistic operating frequencies.
• Leakage & Loss Characteristics — Leakage current conforms to I ≤ 3√C µA (after 5 minutes at rated voltage, 20°C) and tan δ is specified at 0.20 max (120 Hz, 20°C).
• Safety Features — Pressure relief vent design to operate without dangerous conditions under abnormal voltage events, per series safety performance data.
• Mechanical & Packaging — Snap‑in radial can package, dimensions L: 2.5 cm × D: 3.5 cm (φ35 × 25L), polarized construction, supplied in tray packing for production assembly.
• Shelf Life — Shelf life specification: after 1000 hours storage at 105°C (no load) and subsequent voltage treatment, capacitance and loss stay within series shelf‑life limits.

Typical Applications

• General‑Purpose Power Electronics — Suitable for circuits requiring a polarized 180 µF, 400 V capacitor in a snap‑in format for smoothing and energy storage.
• High‑Temperature Environments — Applicable where operation up to 105°C and documented 2000‑hour endurance at that temperature are required.
• Production Assembly — Tray packing and snap‑in terminals support high‑volume PCB assembly and secure board retention.

Unique Advantages

• High Voltage Handling — 400 V rating enables use in higher‑voltage power circuits without up‑rating multiple lower‑voltage components.
• Thermal Endurance — 2000 hours at 105°C under rated conditions provides predictable life performance in elevated‑temperature applications.
• Measured Ripple Performance — Specified ripple currents at both 120 Hz and 10 kHz allow designers to assess performance across common operating frequencies.
• Robust Safety Provision — Pressure relief vent design reduces risk during abnormal voltage conditions, aligning with series safety performance requirements.
• Production‑Friendly Packaging — Tray packing and snap‑in design simplify handling and installation for mass production runs.
