LAQ2P681MELC35

The LAQ2P681MELC35 is a snap‑in terminal aluminum electrolytic capacitor in Nichicon’s LAQ series, specified for general‑purpose electrical applications. It delivers 680 µF capacitance at a 220 V rated voltage in a smaller-sized radial can with snap‑in mounting.

Designed for elevated operating temperatures up to 105°C and long endurance, this part targets assemblies that require high-voltage bulk capacitance with robust thermal and ripple handling characteristics.

Key Features

• Capacitance & Voltage — 680 µF nominal capacitance at 220 V rated voltage, with ±20% tolerance.
• High‑temperature operation — Rated for operation from −25°C to +105°C, with endurance specified for 2000 hours at 105°C under DC bias plus rated ripple current.
• Snap‑in, radial can package — Snap‑in terminal type and radial can construction for secure board mounting; dimension listed as 3.5 × 3.5 cm (L × D).
• Ripple current capability — 1.75 A at 120 Hz and 2.1 A at 10 kHz, supporting both low‑ and high‑frequency ripple conditions.
• Leakage current specification — Leakage current after 5 minutes at 20°C is specified as I ≤ 3√C (µA), providing a verifiable acceptance criterion.
• Dissipation factor (tan δ) — tan δ specified at 0.20 max (120 Hz, 20°C); endurance limits allow tan δ up to 200% of initial under the 2000 h test.
• Safety features — LAQ series safety performance includes a pressure relief vent designed to operate without dangerous conditions under abnormal voltage events.
• Polarized device — Polarized electrolytic construction for correct polarity installation in DC circuits.

Typical Applications

• General‑purpose electronic equipment — Suited to applications that require a 220 V, 680 µF snap‑in aluminum electrolytic capacitor for bulk capacitance in general‑purpose circuits.
• PCB assemblies using snap‑in mounting — Snap‑in terminals and included PC board hole dimensions support secure board installation in assemblies designed for radial, can‑style electrolytics.
• High‑temperature environments — Appropriate where operation up to 105°C and an endurance rating of 2000 hours at 105°C are required.

Unique Advantages

• High nominal voltage in a compact can — 220 V rating combined with a smaller-sized radial package provides high-voltage bulk capacitance where board space is constrained.
• Rated endurance at elevated temperature — 2000 hours at 105°C (with DC bias plus rated ripple) gives a defined lifetime metric for thermal reliability planning.
• Verified ripple performance — Separate ripple current specifications at 120 Hz and 10 kHz enable designers to assess performance across frequency ranges.
• Measured leakage and loss parameters — Clear leakage current formula (I ≤ 3√C µA after 5 minutes at 20°C) and tan δ limits support predictable performance validation.
• Built‑in safety behavior — Pressure relief venting designed to operate under abnormal voltage conditions reduces the risk of hazardous failure modes.
• Simplified board integration — Snap‑in terminals and standard radial can form factor streamline mechanical and PCB mounting in assemblies accepting snap‑in capacitors.
