LAKW6680MELZ30

The LAKW6680MELZ30 is an aluminum electrolytic snap-in terminal capacitor rated 420 V with a nominal capacitance of 68 µF and ±20% tolerance. It is a general-purpose, radial can (snap-in) capacitor designed for equipment that operates in environments with fluctuating voltages.

Designed to withstand high-temperature stress, this capacitor is specified for operation from −25 °C to +105 °C and supports 2000 hours of applied rated ripple current at 105 °C, providing a stable solution for high‑voltage smoothing and energy storage applications.

Key Features

• Electrical Rating — 68 µF nominal capacitance at 420 V DC with ±20% tolerance for bulk energy storage and filtering in high‑voltage circuits.
• High‑temperature Endurance — Specified for 2000 hours with rated ripple current at 105 °C, enabling reliable performance under sustained thermal stress.
• Ripple Current Performance — Rated ripple current of 450 mA at 120 Hz and 517.5 mA at 10 kHz for effective ripple handling across common power frequencies.
• Operating Temperature Range — −25 °C to +105 °C to accommodate a wide operating environment.
• Snap‑in Radial Can Package — Snap‑in terminal type in a radial can (φ22 × 30 mm) for secure board mounting and mechanical stability.
• Safety and Abnormal Voltage Handling — Series-level improvements for abnormal excessive voltage and a pressure‑relief vent design intended to avoid dangerous failure modes under fault conditions.
• Environmental Compliance — RoHS compliant (2011/65/EU, (EU)2015/863).

Typical Applications

• High‑voltage power equipment — Bulk smoothing and energy storage in equipment operating in fluctuating voltage environments where a 420 V rating is required.
• Industrial power supplies — Filtering and ripple reduction in high‑voltage supply rails that must tolerate elevated temperatures and sustained ripple current.
• General‑purpose high‑voltage circuits — Use in assemblies requiring a polarized, high‑voltage electrolytic capacitor in a snap‑in radial can package.

Unique Advantages

• Extended voltage capability: 420 V rating provides headroom for higher‑voltage designs within the LAK series range.
• Proven high‑temperature life: 2000 hours at 105 °C under rated ripple current reduces the need for frequent replacements in thermally demanding applications.
• Measurable ripple handling: Defined ripple current values at 120 Hz and 10 kHz allow designers to match the capacitor to expected operating conditions.
• Secure board mounting: Snap‑in terminal radial can (φ22 × 30 mm) offers mechanical stability for vertical mounting and through‑hole assemblies.
• Built‑in safety features: Pressure‑relief venting and series improvements for abnormal voltages help mitigate hazardous failure modes.
• RoHS compliant: Meets regulatory requirements for restricted substances in many regions.
