LAQ2G390MELZ25

The LAQ2G390MELZ25 is a snap‑in terminal aluminum electrolytic capacitor from Nichicon's LAQ series, specified at 39 µF and 400 V. Designed for general‑purpose applications, it combines a compact φ22 × 25 mm radial can with rated ripple handling and extended endurance for demanding power environments.

Key value comes from its 400 V rating, measurable low leakage, and a 2000‑hour endurance at 105°C, making it suitable for assemblies that require dependable high‑voltage capacitance in a snap‑in package.

Key Features

• High Voltage Rating — Rated for 400 V operation, suitable where elevated DC voltages are required.
• Rated Capacitance and Tolerance — 39 µF with ±20% tolerance (120 Hz, 20°C) for predictable charge storage behavior.
• Snap‑in Radial Can Package — φ22 × 25 mm radial, snap‑in terminal construction for secure board mounting and mechanical stability.
• Ripple Current Capability — 300 mA at 120 Hz (low frequency) and 345 mA at 10 kHz (high frequency) to support AC ripple and switching environments.
• Low Leakage Current — Specified leakage current of 370 µA for controlled stand‑by and bias conditions.
• High‑Temperature Endurance — Rated life of 2000 hours at 105°C under D.C. bias plus rated ripple current, with defined limits for capacitance, tan δ and leakage after test.
• Safety Vent — Pressure relief vent design to mitigate abnormal pressure build‑up without creating dangerous conditions.
• Tray Packing, Mass Production — Supplied in tray format and intended for mass production use.

Typical Applications

• General‑Purpose Electronics — Use where a compact 39 µF, 400 V electrolytic capacitor is required for general energy storage and decoupling in assemblies.
• Power Supply Filtering — Suitable for filtering and smoothing in circuits that require 400 V voltage capability and up to 300 mA–345 mA ripple handling.
• Industrial Control Modules — Applicable in control assemblies operating within −25°C to 105°C and requiring long endurance at elevated temperature.
• High‑Voltage DC Circuits — Appropriate for DC environments that benefit from low leakage (370 µA) and snap‑in mechanical mounting.

Unique Advantages

• 400 V capability: Enables use in higher‑voltage designs without changing capacitor family.
• Compact footprint: φ22 × 25 mm snap‑in can balances space savings with robust mounting.
• Defined ripple performance: Dual ripple specifications (120 Hz and 10 kHz) let designers size capacitors for both low‑ and high‑frequency ripple conditions.
• Long thermal endurance: 2000 hours at 105°C provides predictable aging and reliability metrics for thermal stress planning.
• Controlled leakage: 370 µA leakage current supports stable bias behavior in circuits sensitive to standby current.
• Safety‑oriented design: Pressure relief venting reduces the risk of hazardous failure modes under abnormal conditions.
