LAQ2P821MELC40ZB

The LAQ2P821MELC40ZB is a smaller-sized aluminum electrolytic capacitor in a radial, snap-in can package designed for general-purpose power applications. It provides 820 µF nominal capacitance at a 220 V rating with snap-in mounting for secure board installation.

Designed for elevated-temperature duty, this part is specified for operation from -25 °C to +105 °C and includes endurance and safety characteristics intended for demanding thermal and ripple environments (2000 hours at 105 °C endurance and a pressure relief vent for safety during abnormal conditions).

Key Features

• Capacitance & Voltage — 820 µF nominal capacitance with a 220 V rated voltage suitable for higher-voltage DC link and power supply applications.
• Snap-in Radial Can Package — Snap-in terminal type in a radial, can-style package for robust mechanical retention and straightforward PCB assembly.
• Operating Temperature & Endurance — Rated for -25 °C to +105 °C with 2000 hours endurance at 105 °C under D.C. bias plus rated ripple current.
• Ripple Current — Specified ripple handling of 2.11 A at 120 Hz and 2.532 A at 10 kHz, enabling effective smoothing and filtering in power circuits.
• Leakage Current — Leakage current specified as I ≤ 3√C μA after 5 minutes application of rated voltage at 20 °C (C = rated capacitance in μF), giving a defined leakage performance baseline.
• Dissipation Factor (tan δ) — tan δ specified at 0.20 max (120 Hz, 20 °C), with endurance limits defined (tan δ ≤ 200% of initial specified value after endurance test).
• Tolerance & Polarization — Polarized capacitor with ±20% capacitance tolerance at 120 Hz, 20 °C.
• Safety Design — Pressure relief vent designed to operate under abnormal conditions to avoid dangerous outcomes such as flames or dispersion of parts.

Typical Applications

• Power supply smoothing — Bulk smoothing and energy storage on DC bus and power supply rails where 220 V rating and high-temperature endurance are required.
• Industrial power electronics — Filtering and decoupling in industrial converters and controllers that demand sustained performance up to 105 °C.
• General-purpose high-voltage circuits — General-purpose capacitor use in higher-voltage assemblies that require snap-in mounting and reliable safety relief behavior under abnormal conditions.

Unique Advantages

• High-voltage capability: 220 V rating supports higher-voltage DC link and power supply topologies without component substitution.
• Thermal endurance: 2000 hours rated life at 105 °C under DC bias plus rated ripple current provides predictable long-term behavior in hot environments.
• Defined ripple performance: Ripple current specifications at both 120 Hz and 10 kHz let designers size capacitors for real-world ripple spectra.
• Clear leakage specification: Leakage current defined by I ≤ 3√C μA after voltage application gives a measurable acceptance criterion for assemblies and testing.
• Snap-in mounting: Radial snap-in terminals simplify mechanical retention and PCB assembly for through-hole power modules.
• Safety-minded construction: Pressure relief vent and abnormal-voltage test criteria support safer operation under fault conditions.
