LAK2G181MELC25

The LAK2G181MELC25 is a snap‑in terminal aluminum electrolytic capacitor from Nichicon’s LAK series designed for general‑purpose power applications. It provides 180 µF capacitance at a 400 V rating and is built for sustained operation in elevated temperature environments up to 105°C.

Engineered for systems exposed to voltage fluctuations, the LAK2G181MELC25 combines high ripple handling, a proven 2000‑hour endurance at 105°C, and safety features appropriate for equipment operating under demanding electrical conditions.

Key Features

• Capacitance & Voltage — 180 µF rated capacitance with a 400 V rated voltage for high‑voltage power filtering and energy storage.
• Temperature & Endurance — Specified operating temperature range −25°C to +105°C and endurance of 2000 hours at 105°C under rated ripple current.
• Ripple Performance — Low‑frequency ripple current 800 mA (120 Hz) and high‑frequency ripple current 920 mA (10 kHz) to support demanding AC ripple conditions.
• Leakage & Dissipation — Leakage current specified at 800 µA and tangent of loss angle (tan δ) 0.20 (measured at 20°C, 120 Hz) for predictable loss and leakage behavior.
• Safety Design — LAK series includes improved safety features for abnormally excessive voltage and a pressure relief vent design to mitigate hazardous failure modes.
• Package & Mounting — Radial can with snap‑in terminals (snap‑in mounting) and tray packing for efficient handling and assembly.
• RoHS Compliance — Compliant with RoHS directives.

Typical Applications

• Equipment subject to voltage fluctuations — Suitable for filtering and smoothing in systems where supply voltage varies, leveraging the LAK series’ enhanced abnormal‑voltage tolerance.
• High‑temperature power electronics — Designed for use where ambient temperatures approach 105°C and continuous ripple endurance is required.
• General‑purpose power systems — Appropriate for general power supply decoupling, bulk charge storage, and smoothing in a wide range of industrial and electronic equipment.

Unique Advantages

• High voltage capability: 400 V rating supports higher‑voltage power rails without series stacking.
• Long high‑temperature life: Rated 2000 hours at 105°C under rated ripple, reducing replacement frequency in thermal stress environments.
• Strong ripple handling: 800 mA (120 Hz) and 920 mA (10 kHz) ripple ratings enable reliable AC ripple absorption across common power conversion frequencies.
• Predictable electrical behavior: Specified leakage current (800 µA) and tan δ (0.20 at 20°C/120 Hz) help designers budget loss and leakage in power budgets.
• Enhanced safety features: Series‑level pressure relief and abnormal‑voltage tolerance reduce risk in voltage‑fluctuating applications.
• Serviceable form factor: Snap‑in radial can in tray packing for straightforward board assembly and replacement handling.
