LAQ2P391MELZ45

The LAQ2P391MELZ45 is a snap-in, aluminum electrolytic capacitor designed for general-purpose power applications. It combines a 390 µF capacitance with a 220 V rated voltage in a compact snap-in can package for board-mounted power filtering and energy storage.

Engineered for elevated-temperature operation, this part supports operation from −25 °C to +105 °C and is specified for 2000 hours endurance at 105 °C under rated conditions, providing measurable reliability for industrial and general electronic assemblies.

Key Features

• Capacitance & Voltage — 390 µF nominal capacitance with a 220 V rated voltage and ±20% tolerance at 120 Hz, 20 °C, suitable for high-voltage DC systems within the specified rating.
• Snap-in Can Package — Radial, can-type snap-in construction for secure board mounting and straightforward PCB assembly in power assemblies.
• Temperature & Endurance — Operating range −25 °C to +105 °C and specified life of 2000 hours at 105 °C with DC bias plus rated ripple current applied; after endurance test, capacitance remains within ±20% of initial value.
• Ripple Current Ratings — Rated ripple current of 1.35 A at 120 Hz and 1.62 A at 10 kHz, enabling use where AC ripple is present under rated conditions.
• Leakage and Loss Characteristics — Leakage current specified as I ≤ 3 × √C µA after 5 minutes at 20 °C (C in µF); tangent of loss angle (tan δ) max 0.20 at 120 Hz, 20 °C.
• Safety Features — Pressure relief vent designed to operate under abnormal conditions; safety test parameters are defined for the relevant voltage and capacitance ranges in the datasheet.
• Compact Footprint — Smaller-sized construction with overall dimensions of L: 4.5 × D: 2.2 cm, offering space-efficient bulk capacitance for board-level power designs.

Typical Applications

• Power supply filtering — Bulk smoothing and ripple reduction in 220 V DC power rails where rated voltage and ripple current handling are required.
• Industrial power assemblies — Energy storage and decoupling in industrial control and power conversion equipment operating within the specified temperature and endurance limits.
• General-purpose electronic equipment — Board-level bulk capacitance for assemblies requiring polarized aluminum electrolytic capacitors with snap-in mounting and defined high-temperature endurance.

Unique Advantages

• Designed for elevated-temperature duty — Specified operation and endurance at up to 105 °C with a 2000-hour rated life, providing predictable performance in hot environments.
• Measured ripple capability — Published ripple current values at 120 Hz and 10 kHz allow designers to evaluate thermal and ripple performance against system conditions.
• Clear electrical limits — Leakage current and tan δ specifications are provided with standard test conditions for straightforward qualification in designs.
• Safety-tested construction — Pressure relief vent and defined safety test voltages and limited DC current criteria in the datasheet give a clear basis for safe abnormal-voltage behavior.
• Compact, board-friendly form — Snap-in radial can package delivers large capacitance in a smaller footprint for tighter layouts.
• Manufacturer pedigree — Produced by Nichicon and supplied as part of the LAQ series, with datasheet-backed specifications for design verification.
