LAQ2G151MELZ40

The LAQ2G151MELZ40 is a snap‑in terminal aluminum electrolytic capacitor from Nichicon’s LAQ series, offering 150 µF capacitance at a 400 V rated voltage. It is designed for general‑purpose applications that require high‑voltage bulk capacitance in a compact snap‑in can.

Key value comes from its combination of 400 V rating, high ripple handling, specified endurance at elevated temperature, and a compact φ22 × 40 mm package suitable for volume production and tray packing.

Key Features

• Capacitance & Tolerance: 150 µF nominal with ±20% tolerance (measured at 120 Hz, 20°C).
• High Rated Voltage: 400 V DC rating for high‑voltage smoothing and bulk energy storage in general‑purpose designs.
• Snap‑in Radial Can Package: Snap‑in terminal mounting in a φ22 × 40 mm radial can for secure mechanical and electrical connection.
• Operating Temperature and Endurance: Rated for −25°C to +105°C operating range with 2000 hours endurance at 105°C under specified test conditions.
• Ripple Current Capability: 850 mA at 120 Hz (low frequency) and 977.5 mA at 10 kHz (high frequency) to support demanding AC ripple environments.
• Low Leakage Current: Specified leakage current of 730 µA after rated voltage application.
• Loss Angle: tan δ ≤ 0.20 at 120 Hz, 20°C (series characteristic).
• Safety Vent: Pressure relief vent designed to operate to help prevent dangerous conditions such as flames, ignition or dispersion of parts under abnormal conditions.
• Production Packaging: Supplied in tray packing for volume manufacturing and assembly.

Typical Applications

• High‑voltage power filtering: Bulk smoothing and decoupling in circuits that require 400 V DC rated capacitors and robust ripple handling.
• General‑purpose power electronics: Use where a compact snap‑in electrolytic with 150 µF capacitance and specified endurance at 105°C is needed.
• Ripple‑intensive circuits: Circuits with significant AC ripple benefit from the specified ripple current ratings at both low and high frequencies.

Unique Advantages

• High‑voltage readiness: 400 V rating provides design headroom for high‑voltage DC applications.
• Compact snap‑in form factor: φ22 × 40 mm radial can with snap‑in terminals enables secure mounting while conserving PCB area.
• Thermal endurance: 2000 hours rated life at 105°C supports reliable operation in elevated temperature environments.
• Robust ripple performance: Dual ripple ratings (850 mA @120 Hz and 977.5 mA @10 kHz) address both mains‑frequency and higher‑frequency ripple components.
• Controlled leakage: Low specified leakage current (730 µA) helps preserve system efficiency and minimize standby losses.
• Designed safety feature: Integrated pressure relief vent reduces the risk of hazardous failure modes under abnormal conditions.
