LAQ2D122MELB50ZB

The LAQ2D122MELB50ZB from Nichicon is an aluminum electrolytic, snap‑in terminal capacitor in the LAQ series. It delivers 1.2 mF capacitance at a 200 V rating in a compact φ30 × 50 mm radial can designed for board‑level snap‑in mounting.

Engineered for general‑purpose electronic assemblies, this part offers high ripple handling at both low and high frequencies, a wide operating temperature range and a 2000‑hour endurance rating at 105°C for reliable performance in production environments.

Key Features

• Capacitance & Voltage — 1.2 mF (1200 µF) nominal capacitance with ±20% tolerance and a 200 V rated voltage for energy storage and DC bus use at elevated voltages.
• Snap‑In, Radial Can Package — Snap‑in terminal type in a radial can (φ30 × 50 mm) for secure board mounting and straightforward assembly in tray packing for mass production.
• High Ripple Current — 2.65 A at 120 Hz (low frequency) and 3.18 A at 10 kHz (high frequency), supporting circuits with significant AC ripple content.
• Leakage Current — Specified leakage current of 1460 µA, measured per product test conditions.
• Extended Endurance — 2000 hours at 105°C under rated conditions; capacitance, tan δ and leakage remain within the series’ endurance limits after testing.
• Operating Temperature Range — Rated for −25°C to +105°C to cover a broad range of general‑purpose environmental conditions.

Typical Applications

• General‑purpose electronic assemblies — Intended for use where a 200 V, 1.2 mF snap‑in capacitor is required for board‑level energy storage and decoupling in general applications.
• High‑ripple circuits — Suited for assemblies that require significant ripple handling at both low (120 Hz) and high (10 kHz) frequencies thanks to its specified ripple current ratings.
• Production and assembly‑friendly designs — Offered in tray packing and targeted for mass production workflows where snap‑in mounting and consistent physical dimensions simplify installation.

Unique Advantages

• High voltage capability: 200 V rating enables use in higher‑voltage DC applications while maintaining a compact form factor.
• Dual‑frequency ripple performance: Distinct ripple current specs at 120 Hz and 10 kHz provide quantifiable performance for both low‑ and high‑frequency ripple environments.
• Robust endurance specification: 2000 hours at 105°C gives a defined life expectation under rated stress, helping designers plan for long‑term performance.
• Board retention and assembly efficiency: Snap‑in terminal and radial can packaging support secure mounting and efficient placement in production lines with tray packing.
• Clear electrical characteristics: Tolerance (±20%) and specified leakage current (1460 µA) provide measurable parameters for circuit design and verification.
