LAQ2D681MELZ50ZB

The LAQ2D681MELZ50ZB is a snap-in terminal aluminum electrolytic capacitor from Nichicon’s LAQ series, offering 680 µF capacitance at a 200 V rating. It is designed for general-purpose applications requiring high-voltage bulk capacitance in a radial, snap-in can package.

Built for extended operation across a wide temperature range, this part provides measured ripple handling and long-term endurance suitable for production designs that require stable high-voltage capacitance performance.

Key Features

• Capacitance & Tolerance — 680 µF nominal capacitance with ±20% tolerance (120 Hz, 20°C), providing predictable bulk energy storage.
• Voltage Rating — Rated at 200 V DC to support higher-voltage circuitry; the LAQ series also offers 220 V and 400 V options.
• Ripple Current Capability — 1.75 A at 120 Hz (low frequency) and 2.10 A at 100 kHz (high frequency), supporting both low- and high-frequency ripple environments.
• Leakage Current — Measured leakage current of 1.1 mA, consistent with electrolytic performance expectations after voltage application.
• Endurance — Rated lifetime of 2000 hours at 105°C; after DC bias plus rated ripple current for 2000 hours at 105°C, capacitance remains within ±20% and leakage remains within initial specified values.
• Operating Temperature — -25°C to +105°C operating range for broad environmental applicability.
• Mounting & Package — Snap-in terminal (radial, can - snap-in) for secure board mounting and mechanical retention; physical size φ22 × 50 mm.
• Safety Feature — Pressure relief vent designed to operate under abnormal conditions to avoid dangerous outcomes.
• Packaging & Production — Tray packing; indicated for mass production quantities.

Typical Applications

• General-Purpose Electronics — Suitable where a high-voltage, high-capacitance snap-in electrolytic is required for bulk energy storage and smoothing in general-purpose equipment.
• Industrial Power Modules — Applicable in assemblies that require robust capacitance and specified ripple handling at elevated temperatures.
• High-Voltage Filter Arrays — Used in filter banks and DC link circuits that operate within the part’s 200 V rating and temperature envelope.

Unique Advantages

• High-voltage bulk capacitance: 680 µF at 200 V provides substantial energy storage in a compact radial snap-in can.
• Dual-frequency ripple performance: Rated ripple currents of 1.75 A (120 Hz) and 2.10 A (100 kHz) support designs facing both low- and high-frequency ripple sources.
• Thermal endurance: 2000 hours rated life at 105°C with defined post-test limits on capacitance and leakage ensures predictable aging under high-temperature stress.
• Secure board mounting: Snap-in terminals enable reliable mechanical retention for production assemblies.
• Measured leakage and loss characteristics: Specified leakage current and tan δ limits allow engineers to account for electrical loss and standby current in system budgets.
• Series versatility: Part of the LAQ series, which includes 200 V, 220 V and 400 V options for design scalability within the same family.
