LAKW6151MELB30ZB

The LAKW6151MELB30ZB is a Nichicon LAK series snap‑in terminal aluminum electrolytic capacitor specified at 150 µF and 420 V. It is a radial can, snap‑in type designed for general‑purpose electronic equipment and environments where voltage fluctuation and sustained ripple are present.

Key value comes from its 105°C permissible operating temperature, 2000‑hour endurance under rated ripple at 105°C, and built‑in safety performance for abnormal overvoltage conditions, all while remaining RoHS compliant and supplied in tray packing for production assembly.

Key Features

• Capacitance & Voltage: 150 µF nominal capacitance with a rated voltage of 420 V and capacitance tolerance of ±20% (measured at 120 Hz, 20°C).
• High‑temperature Endurance: Rated to withstand 2000 hours of D.C. bias plus rated ripple current at 105°C, with specified limits on capacitance change, tan δ and leakage after endurance testing.
• Ripple Current Capability: Handles 820 mA at 120 Hz and 943 mA at 10 kHz, enabling stable performance under sustained ripple conditions.
• Low Loss & Leakage: Tangent of loss angle (tan δ) is 0.20 max (120 Hz, 20°C); leakage current specified by I ≤ 3√(C·V) (μA) after 5 minutes at 20°C, with a listed leakage current figure of 750 μA.
• Safety Performance: Designed with a pressure relief vent and improved safety features to mitigate hazardous conditions under abnormally excessive voltage, per series safety ratings.
• Package & Mounting: Radial can, snap‑in terminal type in a φ30 × 30L (30 mm × 30 mm) can size, supplied in tray packing for assembly.
• Environmental Compliance: RoHS compliant.

Typical Applications

• General‑purpose electronic equipment: Bulk capacitance for circuits where a polarized high‑voltage snap‑in electrolytic is required.
• Equipment exposed to voltage fluctuations: Designed specifically for use in systems operating in areas with fluctuating supply voltages, supported by extended voltage range options and safety measures.
• High‑ripple environments: Circuits that subject capacitors to continuous ripple current benefit from the LAK series’ 2000‑hour ripple endurance at 105°C.

Unique Advantages

• High‑voltage capability: 420 V rating supports higher DC applications without changing capacitor family.
• Long service endurance at elevated temperature: 2000 hours at 105°C under rated ripple current provides predictable lifetime behavior in demanding thermal environments.
• Robust ripple handling: Specified ripple currents at both low (120 Hz) and high (10 kHz) frequencies reduce the need for oversized parallel components.
• Built‑in safety features: Pressure relief vent and series safety testing reduce risk during abnormal overvoltage events.
• Production‑friendly packaging: Tray packing supports organized handling and placement for volume assembly.
• Regulatory compliance: RoHS compliance supports use in regions requiring restricted substance adherence.
