LAQ2P821MELB45ZB

The LAQ2P821MELB45ZB is a Nichicon LAQ series aluminum electrolytic capacitor in a snap-in terminal, radial can package designed for general-purpose power applications. It provides 820 µF capacitance at a 220 V rating and is built for operation across a wide temperature range with defined endurance at elevated temperature.

Engineered for systems that require high-voltage bulk capacitance with robust ripple handling, this part combines a compact φ30 × 45 mm snap-in can with rated ripple current capability and 2000-hour endurance at 105°C.

Key Features

• Capacitance & Voltage — 820 µF rated capacitance at 220 V for bulk energy storage and smoothing in high-voltage circuits.
• High-temperature endurance — Rated for operation from -25°C to +105°C with a guaranteed endurance of 2000 hours at 105°C under D.C. bias plus rated ripple current.
• Ripple current capability — Low-frequency ripple current of 2.11 A (120 Hz) and high-frequency ripple current of 2.532 A (10 kHz), supporting demanding AC ripple environments.
• Leakage current — Specified leakage current of 1270 µA; datasheet-based leakage guideline I ≤ 3√C µA after 5 minutes at 20°C is provided for the series.
• Package & mounting — Radial, snap-in (snap-in terminal type) can in a compact φ30 × 45 mm footprint for secure board mounting and ease of assembly; supplied in tray packing.
• Manufacturing status & compliance — Mass production status and RoHS compliant.
• Tolerance — ±20% capacitance tolerance at 120 Hz, 20°C, providing predictable design margins.

Typical Applications

• General-Purpose Power Supplies — Bulk capacitance and smoothing for 220 V systems where stable DC filtering and ripple handling are required.
• Industrial Power Electronics — Suited to general-purpose industrial equipment that requires a 220 V bulk capacitor with 105°C endurance.
• High-Voltage DC Bus — Provides bulk energy storage and ripple attenuation in applications that need 820 µF at 220 V in a compact snap-in package.

Unique Advantages

• 220 V rated bulk capacitance: Provides substantial energy storage at a higher working voltage, enabling compact designs where 220 V capability is required.
• High ripple handling at multiple frequencies: Separate ripple specs for 120 Hz (2.11 A) and 10 kHz (2.532 A) clarify performance across both low- and high-frequency ripple environments.
• Defined high-temperature life: 2000 hours of endurance at 105°C under rated conditions supports reliability in thermally challenging assemblies.
• Compact snap-in form factor: φ30 × 45 mm radial can with snap-in terminals simplifies board mounting while keeping PCB footprint small.
• Measured leakage and series guideline: Product leakage specified at 1270 µA and the LAQ series leakage criterion (I ≤ 3√C µA) give clear parameters for design verification.
• RoHS compliant and production ready: Mass-production status and RoHS compliance ease procurement and regulatory planning.
