LAQ2G331MELC35

The LAQ2G331MELC35 is an aluminum electrolytic capacitor in a snap‑in radial can package designed for general-purpose power circuits. It delivers 330 µF nominal capacitance at a 400 V rating in a compact, smaller-sized footprint with snap‑in terminals for secure PCB mounting.

Engineered for elevated-temperature operation, this capacitor supports an operating range of −25 °C to 105 °C and is specified for 2000 hours of endurance at 105 °C under DC bias plus rated ripple current, offering a verifiable option for applications that require sustained high-temperature performance and DC ripple handling.

Key Features

• Capacitance & Voltage — 330 µF nominal capacitance with a 400 V rated voltage and ±20% tolerance at 120 Hz, 20 °C.
• High‑temperature endurance — Rated for operation up to 105 °C with a specified endurance of 2000 hours at 105 °C when subjected to DC bias plus rated ripple current.
• Snap‑in radial can package — Snap‑in terminal type and radial, can-style package for secure board mounting in demanding assemblies.
• Ripple current capability — Specified ripple current of 1.47 A at 120 Hz and 1.69 A at 100 kHz, supporting designs with continuous ripple load.
• Leakage and loss characteristics — Leakage current specified by I ≤ 3√C µA after 5 minutes at 20 °C; tangent of loss angle (tan δ) ≤ 0.20 at 120 Hz, 20 °C.
• Safety performance — Pressure relief vent design intended to operate under abnormal conditions without hazardous outcomes (no flames, ignition, or dispersion of case pieces).
• Physical size — Smaller-sized body with dimensions L: 3.5 × D: 3.5 cm and a seated height of 1.378 inch, suitable for compact power assemblies.

Typical Applications

• Power supply smoothing and filtering — 330 µF at 400 V supports DC bias and ripple-handling requirements commonly found in high-voltage supply rails.
• DC link and bus capacitors — Specified ripple current and 105 °C endurance make this part appropriate for intermediate energy storage and ripple suppression in power conversion stages.
• Industrial and commercial power modules — Snap‑in mounting and compact dimensions simplify assembly in industrial power supplies and commercial equipment that operate at elevated temperatures.

Unique Advantages

• High voltage capability: 400 V rating provides headroom for a range of high-voltage general-purpose circuits.
• Compact snap‑in package: Radial snap‑in can reduces assembly complexity while saving PCB area compared with larger form factors.
• Verified high-temperature life: Endurance specified at 2000 hours at 105 °C under DC bias plus rated ripple gives measurable long-term performance data for thermal designs.
• Measured ripple handling: Ripple current specifications at both low (120 Hz) and high (100 kHz) frequencies support selection for circuits with different switching characteristics.
• Controlled electrical loss and leakage: tan δ ≤ 0.20 and defined leakage current limits provide predictable behavior for precision power designs.
• Built-in safety vent: Pressure relief vent design mitigates hazardous outcomes during abnormal voltage or pressure events.
