LAQ2D821MELA50ZB

The LAQ2D821MELA50ZB from Nichicon is an aluminum electrolytic capacitor in the LAQ series featuring a snap‑in terminal package. It provides 820 µF capacitance at a 200 VDC rating in a φ25 × 50 mm radial, can‑snap‑in form factor.

Designed for general‑purpose power applications, this part combines high capacitance, elevated temperature endurance and measurable ripple handling to support power filtering and energy‑storage roles in equipment that requires 105°C performance.

Key Features

• Capacitance & Voltage — 820 µF nominal capacitance with a 200 VDC rated voltage and ±20% tolerance for bulk energy storage and decoupling in high‑voltage circuits.
• High‑Temperature Endurance — Rated lifetime of 2000 hours at 105°C, supporting sustained operation in elevated‑temperature environments.
• Ripple Current Handling — Low‑frequency ripple capability of 2.11 A (120 Hz) and high‑frequency ripple capability of 2.532 A (10 kHz) to accommodate AC ripple on DC rails.
• Leakage Current & Polarization — Polarized device with specified leakage current of 1210 µA, suitable for designs that account for electrolytic leakage characteristics.
• Snap‑in Mounting & Package — Radial, snap‑in can package (φ25 × 50 mm) for robust board retention and tray packing for handling and assembly efficiency.
• Safety Design & Marking — Includes a pressure relief vent to mitigate unsafe conditions, and is printed in white on a black sleeve for clear component identification.
• Compliance & Availability — RoHS compliant and in mass production to support volume procurement and deployment.

Typical Applications

• Power supply filtering — Bulk smoothing and energy storage on high‑voltage DC rails where 820 µF at 200 V and elevated temperature endurance are required.
• DC link and intermediate circuits — Decoupling and ripple absorption in general‑purpose power modules using the capacitor’s specified ripple current ratings.
• Industrial and commercial equipment — Use in general‑purpose electronic assemblies that demand 105°C rated endurance and secure snap‑in mounting.

Unique Advantages

• High capacitance at 200 V — Provides substantial charge storage for designs that need bulk capacitance on mid‑to‑high voltage rails.
• Elevated temperature life — 2000 hours at 105°C offers predictable end‑of‑life parameters for thermal environments.
• Measured ripple performance — Separately specified ripple currents at 120 Hz and 10 kHz let designers account for both low‑ and high‑frequency heating effects.
• Secure board mounting — Snap‑in radial can minimizes mechanical movement and supports straightforward through‑hole assembly workflows.
• Safety venting and clear marking — Built‑in pressure relief vent and readable sleeve marking improve serviceability and risk management.
• Production readiness — RoHS compliance and mass production status simplify procurement and regulatory planning.
