LAKW6680MELA25ZB

The LAKW6680MELA25ZB is a Nichicon LAK series aluminum electrolytic capacitor in a snap‑in radial can package. It delivers 68 µF at a 420 V rating with a snap‑in terminal format designed for robust mounting in high‑voltage power circuits.

Engineered for general‑purpose power electronics and equipment operating in voltage‑fluctuating environments, this part offers extended voltage coverage, elevated temperature endurance and built‑in safety features to support reliable filtering and energy buffering in industrial and power conversion systems.

Key Features

• High Voltage Rating — Rated voltage of 420 V suitable for high‑voltage power circuits and DC link applications within its specified limits.
• Capacitance & Tolerance — 68 µF nominal capacitance with ±20% tolerance at 120 Hz, 20°C for predictable filtering performance.
• Temperature and Lifetime — Operating range from −25°C to +105°C with an endurance specification of 2000 hours at 105°C when subjected to rated ripple and DC bias.
• Ripple Current Handling — Rated for 450 mA at 120 Hz (low frequency) and 517.5 mA at 10 kHz (high frequency) to support AC ripple absorption in power stages.
• Leakage Current — Specified leakage current of 500 µA, supporting stable performance after voltage application.
• Safety and Abnormal Voltage Resistance — LAK series improvements include safety features and a pressure relief vent designed to operate without flames or dangerous dispersion under abnormal over‑voltage conditions.
• Package and Mounting — Snap‑in terminal, radial can construction (≈25 mm diameter, 25 mm height) for secure PCB mounting; supplied in tray packing suitable for mass production.
• Regulatory Compliance — RoHS directive compliant.

Typical Applications

• Power supplies and converters — Bulk filtering and smoothing where a high‑voltage capacitor with defined ripple capability is required.
• Industrial power equipment — Energy buffering and voltage‑fluctuation tolerance in machinery and control systems operating at elevated temperatures.
• Inverters and UPS systems — DC link and smoothing roles in systems that demand steady capacitance and high voltage endurance.
• General‑purpose power electronics — Use in designs that require a polar aluminum electrolytic with snap‑in mounting and long life at 105°C.

Unique Advantages

• High‑voltage capability: 420 V rating enables use in higher‑voltage power stages without series stacking.
• Designed for elevated temperature endurance: 2000 hours at 105°C provides predictable aging and endurance data for thermal designs.
• Concrete ripple ratings: Specified ripple currents at both low and high frequencies allow designers to size capacitors against actual ripple loads.
• Safety‑focused construction: Pressure relief vent and series improvements for abnormal voltage handling reduce risk in voltage‑fluctuating environments.
• Production‑ready packaging: Tray packing and snap‑in terminals support reliable assembly and high‑volume manufacturing processes.
• Regulatory compliance: RoHS conformance supports deployment in global markets with restriction of hazardous substances requirements.
