Key value propositions include a compact φ22 × 25 mm package with snap-in mounting for straightforward assembly, rated operation from −25°C to 105°C, and a 2000-hour endurance rating at 105°C for sustained high-temperature performance.

Key Features

• Capacitance & Voltage  39 µF nominal capacitance with a 400 V rated voltage and ±20% tolerance at 120 Hz, 20°C.
• Ripple Current  Specified ripple handling of 300 mA at 120 Hz (low frequency) and 345 mA at 10 kHz (high frequency), supporting AC ripple and decoupling in power circuits.
• Leakage Current  Specified leakage current of 370 µA; series leakage current guideline: I ≤ 3√C (µA) after 5 minutes' application of rated voltage at 20°C (datasheet condition).
• Endurance & Temperature  Rated lifetime of 2000 hours at 105°C under DC bias plus rated ripple current; operational temperature range −25°C to +105°C.
• Package & Mounting  Radial can, snap-in terminal type (φ22 × 25 mm), designed for PCB snap-in mounting and tray packing for production assembly.
• Reliability Characteristics  Endurance criteria per series datasheet: after 2000 hours at 105°C, capacitance change within ±20%, tan δ ≤ 200% of initial, and leakage current ≤ initial specified value.
• Production & Availability  Tray-packed and listed as mass production status for volume manufacturing support.

Typical Applications

• General-purpose power systems  For designs requiring 39 µF at 400 V in a snap-in radial can, the LAQ2G390MELZ25ZB supports bulk capacitance needs in general-purpose power assemblies.
• Industrial and commercial equipment  Suitable where a compact, high-voltage polarized electrolytic with a 2000-hour endurance at 105°C is required.
• Power supply modules and assemblies  Snap-in mounting and tray packing facilitate integration into power supply modules and production assembly lines where consistent form factor and availability matter.

Unique Advantages

• High-voltage capability: 400 V rating allows use in higher-voltage general-purpose designs requiring robust DC voltage handling.
• Compact snap-in package: φ22 × 25 mm radial can with snap-in terminals provides a space-efficient footprint for PCB assembly.
• Defined ripple performance: Specified ripple currents at both 120 Hz and 10 kHz enable designers to account for low- and high-frequency ripple in power circuits.
• Measured low leakage: Specified leakage current of 370 µA and series leakage guideline support predictable biasing and standby loss calculations.
• High-temperature endurance: 2000 hours at 105°C endurance rating with specified post-test limits on capacitance, tan δ and leakage for design reliability.
• Production-ready packaging: Tray packing and mass production status help streamline procurement and assembly for volume builds.
