LAQ2D821MELB35ZB

The LAQ2D821MELB35ZB is an aluminum electrolytic capacitor in Nichicon's LAQ series, offered in a snap-in terminal can for robust mechanical mounting. It provides 820 µF capacitance at a 200 V rating with ±20% tolerance and is specified for general-purpose applications.

Key performance characteristics include dual-frequency ripple current ratings (2.11 A at 120 Hz and 2.532 A at 100 kHz), a leakage current specification of 1210 µA, and a rated endurance of 2000 hours at 105°C. The part is supplied in tray packing for mass production use.

Key Features

• Capacitance & Tolerance — 820 µF nominal with ±20% tolerance (measured at 120 Hz, 20°C), suitable for designs that require defined bulk capacitance at elevated voltage.
• Rated Voltage — 200 V DC rating for higher-voltage general-purpose circuits.
• Ripple Current Performance — Rated low-frequency ripple current of 2.11 A (120 Hz) and high-frequency ripple current of 2.532 A (100 kHz), supporting AC ripple handling across common frequencies.
• Leakage Current — Specified leakage current of 1210 µA.
• Operating Temperature & Endurance — Rated for −25°C to +105°C with 2000 hours endurance at 105°C under rated conditions.
• Package & Mounting — Snap-in terminal, radial can (φ30 × 35 mm), designed for secure mounting in mass-production assemblies; supplied in tray packing.
• Polarized Design — Polarized aluminum electrolytic capacitor for DC applications.

Typical Applications

• General-purpose power circuits — Use where 820 µF at 200 V is required and defined ripple-current capability and endurance are important.
• Mass-production assemblies — Snap-in mounting and tray packing simplify installation in high-volume manufacturing environments.
• Elevated-temperature environments — Intended for general-purpose applications needing operation across −25°C to +105°C and up to 2000 hours at 105°C.

Unique Advantages

• 200 V voltage capability: Supports higher-voltage general-purpose applications without changing capacitor series.
• High capacitance in a compact can: 820 µF in a φ30 × 35 mm package provides substantial bulk capacitance in a small footprint.
• Dual-frequency ripple ratings: Defined ripple current specifications at 120 Hz (2.11 A) and 100 kHz (2.532 A) allow designers to assess performance across common operating frequencies.
• Elevated-temperature endurance: Rated for 2000 hours at 105°C, supporting designs that require sustained performance under heat stress.
• Manufacturing-ready packaging: Tray packing and snap-in terminals facilitate automated assembly and reliable mechanical retention.
• Clear electrical limits: Specified leakage current (1210 µA) and ±20% capacitance tolerance provide predictable behavior for design verification.
