LAK2G181MELZ50ZB

The LAK2G181MELZ50ZB is a snap‑in, radial can aluminum electrolytic capacitor from Nichicon’s LAK series designed for general‑purpose power applications. It provides 180 µF capacitance at a 400 V rating with a working temperature range of −25 °C to +105 °C.

Engineered for robust ripple handling and safety under abnormal voltage conditions, this part targets mass‑production assemblies where secure snap‑in mounting, extended endurance and regulatory compliance are required.

Key Features

• Core electrical specs: 180 µF capacitance with ±20% tolerance (120 Hz, 20 °C) and a 400 V rated voltage for higher‑voltage DC applications.
• High temperature endurance: Qualified for 2000 hours at 105 °C under rated conditions; meets endurance criteria for capacitance change, tan δ and leakage current after the specified test.
• Ripple current capability: 800 mA at 120 Hz and 920 mA at 10 kHz, suited for applications with continuous AC ripple stress.
• Snap‑in radial can package: φ22 × 50 mm body (approx. 5 × 2.2 cm) with snap‑in terminals for secure board or chassis mounting and efficient mass production handling (tray packing).
• Safety features: Designed with improved safety against abnormally excessive voltage and a pressure relief vent that operates without generating flames or hazardous dispersal under specified test conditions.
• Polarized, general‑purpose use: Polar capacitor intended for standard DC filtering and energy‑storage roles in general equipment applications.
• Regulatory compliance: RoHS compliant per the provided product information.

Typical Applications

• Industrial power equipment: Filtering and smoothing in equipment exposed to fluctuating supply voltages where endurance at elevated temperature is required.
• Power supplies and converters: Bulk capacitance and ripple handling in higher‑voltage DC power stages using snap‑in mounting for secure assembly.
• Mass‑production assemblies: Tray packing and snap‑in terminals facilitate automated handling and reliable installation in production builds.

Unique Advantages

• Proven high‑temperature life: 2000‑hour endurance at 105 °C helps maintain capacitance and leakage specifications over prolonged thermal stress.
• Higher voltage rating: 400 V capability supports designs operating at elevated DC voltages without up‑rating multiple lower‑voltage parts.
• Robust ripple performance: Defined ripple current ratings at both low and high frequencies allow confident selection for systems with significant AC ripple content.
• Snap‑in stability: Radial snap‑in package provides mechanical retention and simplifies placement in power enclosures or PCB assemblies.
• Built‑in safety behavior: Pressure relief and abnormal voltage protections reduce risk during overvoltage events as described in the product specifications.
• RoHS compliant: Meets RoHS requirements for environmentally conscious product designs.
