LAQ2G271MELC35ZB

The LAQ2G271MELC35ZB is a snap-in terminal aluminum electrolytic capacitor from Nichicon’s LAQ series. It provides 270 µF capacitance with a 400 V rated voltage and is designed for general-purpose electronic applications where high ripple tolerance and elevated operating temperature endurance are required.

This radial can, snap-in package delivers measurable performance: 1300 mA ripple current at 120 Hz and 1495 mA at 100 kHz, a rated operating temperature range of −25°C to +105°C, and a 2000-hour endurance at 105°C.

Key Features

• High Voltage Rating — 400 V rated voltage suitable for high-voltage general-purpose circuits.
• Capacitance and Tolerance — 270 µF with ±20% tolerance at 120 Hz and 20°C for predictable bulk energy and filtering behavior.
• Ripple Current Performance — 1.300 A ripple current at 120 Hz and 1.495 A at 100 kHz to support applications with significant AC ripple across a range of frequencies.
• Temperature and Endurance — Rated for −25°C to +105°C operation with a specified endurance of 2000 hours at 105°C under DC bias plus rated ripple current.
• Loss and Leakage Characteristics — tan δ (DF) of 0.20 maximum at 20°C and 120 Hz, and a measured leakage current of 980 µA.
• Package and Mounting — Radial, can-type with snap-in terminals for secure board mounting; supplied in tray packing for production assembly.
• Safety Performance — Pressure relief vent designed to operate without dangerous conditions such as flames or dispersion of parts in abnormal conditions, per series safety specifications.

Typical Applications

• General Purpose Designs — Suitable for general-purpose electronic applications that require a 400 V rated electrolytic capacitor with 270 µF capacitance.
• High-Ripple Environments — Appropriate where elevated ripple currents are present at low and high frequencies, leveraging the 1.300 A (120 Hz) and 1.495 A (100 kHz) ratings.
• High-Temperature Endurance Needs — Useful in designs requiring sustained performance at elevated temperatures up to +105°C and verified 2000-hour endurance at that temperature.

Unique Advantages

• High-Voltage Capability: 400 V rating enables use in higher-voltage circuits without additional derating complexity.
• Frequency-Range Ripple Handling: Separate ripple current specifications at 120 Hz and 100 kHz provide clarity for both low- and high-frequency design needs.
• Proven Endurance at Elevated Temperature: 2000 hours at 105°C under DC bias plus rated ripple current supports long-term thermal reliability in demanding environments.
• Clear Electrical Characteristics: Specified tan δ and leakage current values (0.20 max tan δ; 980 µA leakage) simplify selection and verification during design validation.
• Production-Friendly Packaging: Tray packing and snap-in radial can format streamline handling and assembly for mass production runs.
• Built-in Safety Feature: Pressure relief vent designed to operate safely under abnormal conditions per LAQ series specifications.
