LAQ2D561MELZ45ZB

The LAQ2D561MELZ45ZB from Nichicon is a snap‑in terminal aluminum electrolytic capacitor in the LAQ series, rated at 560 µF and 200 V. It is a polarized, radial can-style capacitor designed for general-purpose power applications that require a compact, high‑voltage electrolytic solution.

Key value comes from its combination of 2000 h endurance at 105°C, snap‑in mounting for secure board installation, and documented ripple performance across low and high frequencies, making it suitable for designs requiring reliable bulk capacitance at elevated temperatures.

Key Features

• Capacitance & Voltage — 560 µF nominal capacitance with a 200 V rated voltage and ±20% tolerance (120 Hz, 20°C).
• Temperature Rating — Operates across −25°C to +105°C with a specified endurance of 2000 hours at 105°C.
• Mounting & Package — Snap‑in terminal, radial can (φ22 × 45 mm) designed for secure mechanical retention and easy through‑hole assembly; supplied in tray packing for production use.
• Ripple Current Performance — 1600 mA at 120 Hz (low frequency) and 1920 mA at 10 kHz (high frequency), supporting AC ripple handling in power circuits.
• Leakage & Dissipation — Listed product leakage current: 1000 µA. Series datasheet provides a leakage current specification formula (I ≤ 3√C µA after 5 minutes at rated voltage, 20°C) and a tangent of loss angle (tan δ) ≤ 0.20 at 120 Hz, 20°C.
• Endurance & Safety — Meets endurance criteria after DC bias plus rated ripple current for 2000 hours at 105°C; includes pressure relief venting as specified in the series datasheet.

Typical Applications

• Power supply smoothing — Bulk capacitance for DC link and filter stages where 560 µF at 200 V is required and snap‑in mounting is preferred.
• Industrial power electronics — Use in high‑voltage general‑purpose circuits that operate up to 105°C and require documented ripple handling at 120 Hz and 10 kHz.
• General‑purpose circuit designs — Suitable where a polarized, radial aluminum electrolytic capacitor with tray packing is needed for mass production assembly.

Unique Advantages

• High voltage capacity: 200 V rating provides headroom for higher‑voltage DC systems while delivering 560 µF of capacitance.
• Thermal endurance: Rated for 2000 hours at 105°C, supporting sustained operation in elevated temperature environments per the LAQ series endurance specification.
• Dual‑frequency ripple data: Specified ripple current at both 120 Hz and 10 kHz (1.6 A and 1.92 A respectively) enables designers to size capacitors based on real ripple conditions.
• Robust mounting: Snap‑in radial can package (φ22 × 45 mm) provides mechanical stability for through‑hole applications and production assembly compatibility.
• Traceable series specifications: Series datasheet supplies formal limits for leakage current, tan δ, endurance and safety testing, enabling predictable design margins.
