LAQ2P681MELC35ZB

The LAQ2P681MELC35ZB from Nichicon is a snap‑in terminal aluminum electrolytic capacitor in the LAQ series, rated 680 µF with ±20% tolerance at 220 V. It is a radial, can‑style snap‑in device sized φ35 × 35L and designed for general‑purpose electronic and power applications.

Key performance attributes include high ripple handling at both low and high frequencies, a defined leakage current, and a 2000‑hour endurance rating at 105°C—making it suitable for applications that require stable bulk capacitance under elevated temperature and continuous ripple stress.

Key Features

• Capacitance & Voltage: 680 µF nominal capacitance with a 220 V rated voltage and ±20% tolerance for predictable bulk energy storage.
• Snap‑in Radial Package: Radial, can-style snap‑in mounting (φ35 × 35L) for secure mechanical and electrical connection in power assemblies.
• Ripple Current Handling: Rated ripple current of 1.75 A (120 Hz) and 2.10 A (10 kHz) to support both low‑ and high‑frequency ripple conditions.
• Leakage Current: Specified leakage current of 1.16 mA for controlled standby losses and consistent behavior after voltage application.
• High‑Temperature Endurance: 2000 hours life at 105°C under D.C. bias plus rated ripple current, with restoration to 20°C meeting defined capacitance, tan δ and leakage limits.
• Operating Temperature Range: −25°C to +105°C to accommodate elevated ambient and internal operating temperatures.
• Safety Feature: Series safety performance includes a pressure relief vent designed to operate under abnormal conditions without dangerous dispersion of parts.
• Production‑friendly Packaging: Available in tray packing for mass production and automated handling.

Typical Applications

• General‑purpose power electronics: Bulk capacitance and ripple handling for smoothing and energy storage in general‑purpose designs.
• Power supplies and converters: 220 V rating combined with defined ripple current and 105°C endurance supports use in converter and supply circuits operating at elevated temperatures.
• Industrial equipment: Robust operating range and long life at 105°C make this capacitor suitable for continuous operation in industrial power modules and control systems.

Unique Advantages

• High ripple capability across frequencies: Separate low‑ and high‑frequency ripple ratings (1.75 A at 120 Hz, 2.10 A at 10 kHz) enable reliable performance under mixed ripple spectra.
• Defined high‑temperature endurance: 2000 hours at 105°C with post‑test limits on capacitance, tan δ and leakage for predictable long‑term behavior.
• Compact, serviceable package: φ35 × 35L snap‑in can provides a robust mechanical mount and convenient board attachment for power assemblies.
• Controlled leakage: Specified leakage current of 1.16 mA supports designs that require known standby loss characteristics.
• Series safety considerations: Pressure relief vent functionality reduces risk under abnormal conditions without dispersion of parts.
• Manufacturing ready: Tray packing and mass‑production availability simplify procurement and high‑volume assembly flows.
