LAQ2P821MELB45

The LAQ2P821MELB45 is a snap-in terminal aluminum electrolytic capacitor from Nichicon’s LAQ series, rated 820 µF at 220 V with ±20% tolerance. It is a radial can, snap-in package designed for general-purpose power electronics where high-voltage filtering and bulk energy storage are required.

Built for elevated-temperature operation and extended endurance, this part offers specified ripple current capability at both low and high frequencies and is RoHS compliant, making it suitable for a wide range of industrial and general-purpose equipment designs.

Key Features

• Electrical Performance — 820 µF nominal capacitance with ±20% tolerance and 220 V rated voltage for high-voltage DC circuits.
• Ripple Current Capability — Rated ripple current of 2.11 A at 120 Hz and 2.532 A at 100 kHz to support smoothing and decoupling under AC ripple loading.
• Leakage Current — Specified leakage current of 1270 µA to support predictable standby and bias behavior after voltage application.
• High-Temperature Endurance — Designed for operation from −25 °C to +105 °C with a rated endurance of 2000 hours at 105 °C under DC bias plus rated ripple current.
• Safety and Reliability — Includes pressure relief venting and safety performance tested per series specifications to reduce risk under abnormal voltage stress.
• Package and Mounting — Snap-in radial can (φ30 × 45L / 4.5 × 3.0 cm) for secure board retention and tray packing for volume production handling.
• Environmental Compliance — RoHS compliant (2011/65/EU,(EU)2015/863).

Typical Applications

• Power Supplies — Bulk smoothing and DC bus decoupling on 220 V rails where high capacitance and ripple-handling are required.
• Industrial Equipment — Filtering and energy buffering in general-purpose industrial electronics that operate across −25 °C to +105 °C and demand extended endurance.
• Energy Storage Buffers — Local energy reservoir and transient suppression in systems needing stable capacitance and defined leakage behavior under load.

Unique Advantages

• 220 V Rated Voltage: Enables use directly on higher-voltage DC circuits without additional series components.
• Dual-Frequency Ripple Ratings: Explicit ripple current specs at 120 Hz and 100 kHz allow designers to size capacitors for both low- and high-frequency ripple environments.
• Extended High-Temperature Life: 2000 hours endurance at 105 °C under rated conditions provides predictable long-term performance in hot operating environments.
• Secure Snap-In Mounting: Snap-in terminals offer robust board retention for equipment subject to vibration or handling during assembly.
• Compact Can Footprint: φ30×45L form factor (4.5 × 3.0 cm) balances capacitance with a space-conscious package for dense PCB layouts.
• RoHS Compliance: Meets applicable environmental restrictions for easier integration into regulatory-conscious designs.
