LAQ2D391MELA30

The LAQ2D391MELA30 is a Nichicon LAQ series aluminum electrolytic capacitor in a snap-in terminal (radial can) package designed for general-purpose power applications. It provides 390 µF capacitance at a 200 V rating with a compact φ25 × 30 mm footprint and tray packing for production assembly.

Key design attributes include high ripple-handling capability (1.35 A at 120 Hz, 1.62 A at 10 kHz), a 2000 hour endurance rating at 105 °C, low loss (tan δ ≤ 0.20 at 20 °C, 120 Hz) and a specified leakage current of 830 µA, making it suitable where sustained high-voltage bulk capacitance and durability are required.

Key Features

• Capacitance & Voltage — 390 µF nominal capacitance with a 200 V rated voltage and ±20% tolerance at 120 Hz, 20 °C.
• Snap-in Radial Package — Snap-in terminal type in a radial can for secure board mounting and mechanical stability in through-hole assemblies; physical size φ25 × 30 mm.
• High Ripple Current — Rated ripple current of 1.35 A at 120 Hz (low frequency) and 1.62 A at 10 kHz (high frequency) for effective AC stress handling.
• Thermal & Endurance Ratings — Operating temperature range −25 °C to +105 °C with a rated life of 2000 hours at 105 °C under DC bias plus rated ripple current.
• Low Loss & Controlled Leakage — Tan δ ≤ 0.20 (20 °C, 120 Hz) and leakage current specified at 830 µA after voltage application.
• Safety Design — Series safety performance includes a pressure relief vent intended to operate without flames, ignition, or dangerous case dispersion under specified conditions.
• RoHS Compliant & Production Ready — RoHS-compliant material status and mass production availability with tray packing for PCB assembly.

Typical Applications

• General-purpose power filtering — Bulk smoothing and energy storage in 200 V circuits where compact, high-voltage capacitance is required.
• Power supply decoupling — Handling ripple current and stabilizing DC rails in industrial and commercial power supplies.
• High-voltage bulk capacitance — Providing stored charge and transient buffering in systems designed around 200 V rated components.

Unique Advantages

• High-voltage capability: 200 V rating delivers elevated DC voltage handling for higher-voltage power rails without increased capacitance size.
• Robust ripple performance: 1.35 A at 120 Hz and 1.62 A at 10 kHz supports sustained AC stress and reduces heating in high-ripple environments.
• Designed for elevated temperatures: 2000 hour life at 105 °C ensures durability under prolonged high-temperature operation when subjected to rated DC bias and ripple.
• Compact snap-in form factor: φ25 × 30 mm size with snap-in terminals simplifies board layout while providing reliable mechanical retention.
• Measured electrical stability: Specified tan δ ≤ 0.20 and controlled leakage current (830 µA) provide predictable loss and leakage characteristics for design validation.
• Safety features included: Pressure relief vent behavior is designed to prevent dangerous outcomes such as flames or case dispersion under specified conditions.
