LAQ2G151MELB25ZB

The LAQ2G151MELB25ZB from Nichicon is an aluminum electrolytic, snap‑in terminal capacitor in the LAQ series, designed for general‑purpose power applications. It delivers 150 µF at 400 V with ±20% tolerance and is supplied in tray packing for mass production.

Engineered for elevated operating stress, the device is specified for -25°C to 105°C operation and a 2000‑hour endurance at 105°C under rated DC bias plus ripple current, providing predictable performance in high‑temperature environments.

Key Features

• Capacitance & Voltage — 150 µF rated capacitance at 400 V with ±20% tolerance, offering substantial bulk capacitance for high‑voltage circuits.
• Snap‑in Mounting — Snap‑in terminal, radial can package (φ30 × 25 mm), designed for secure board mounting and mechanical stability in panel or PCB assemblies.
• High‑Temperature Endurance — Rated for operation from -25°C to 105°C with a 2000‑hour lifetime at 105°C when subjected to DC bias plus rated ripple current.
• Low Loss (tan δ) — Specified tan δ of 0.20 max at 20°C and 120 Hz, supporting efficient energy handling with controlled dielectric losses.
• Ripple Current Capability — 850 mA at 120 Hz (low frequency) and 977.5 mA at 10 kHz (high frequency), enabling use where continuous ripple handling is required.
• Low Leakage Current — Rated leakage current of 730 µA, helping minimize standby current and reduce power loss.
• Safety Vent — Pressure relief vent included to operate under abnormal conditions without dangerous outcomes, per series safety performance details.

Typical Applications

• General‑purpose power filtering — Provides bulk capacitance and smoothing at 400 V for general‑purpose power supplies and conversion stages.
• High‑temperature environments — Suited to applications that require sustained performance at elevated temperatures up to 105°C with defined endurance.
• Ripple‑intensive circuits — Used where significant ripple current must be absorbed, leveraging the specified 120 Hz and 10 kHz ripple ratings.

Unique Advantages

• Robust high‑voltage capability: 400 V rating enables deployment in higher DC bus and power supply designs without voltage derating within specification.
• Compact snap‑in form factor: φ30 × 25 mm can and snap‑in terminals deliver a space‑efficient solution for applications requiring secure mechanical mounting.
• Predictable high‑temperature life: 2000 hours at 105°C under rated conditions gives designers quantifiable endurance for thermal budgeting and reliability planning.
• Measured ripple handling: Specified ripple currents at 120 Hz and 10 kHz allow designers to size capacitors based on both line‑frequency and switching‑frequency stress.
• Controlled leakage and loss: 730 µA leakage and tan δ ≤ 0.20 at 20°C/120 Hz support efficient system standby behavior and low dissipation.
• Series safety provisions: Pressure relief vent behavior is defined to avoid dangerous outcomes under abnormal conditions, supporting safer system design.
