LAKW6221MELC35ZB

The LAKW6221MELC35ZB from Nichicon is a snap‑in, large‑can aluminum electrolytic capacitor designed for general‑purpose power applications. This radial, can‑snap‑in package delivers 220 µF at a 420 V rating with polarized terminals and tray packing for production handling.

Engineered for reliability under elevated temperatures and varying line conditions, the LAK series construction provides 2000 hours endurance at 105°C, enhanced safety features for abnormal overvoltage, and rated ripple handling for both low‑ and high‑frequency environments.

Key Features

• Electrical Performance — 220 µF nominal capacitance with tolerance −20% to +20%, rated for 420 V DC and polarized operation for bulk energy storage and filtering.
• High‑Temperature Endurance — Rated operating range −25°C to +105°C with specified life/endurance of 2000 hours at 105°C when subjected to rated ripple current and D.C. bias.
• Ripple Current Capability — Low‑frequency ripple current 1.00 A (120 Hz) and high‑frequency ripple current 1.15 A (100 kHz), supporting both mains ripple filtering and higher frequency power electronics noise suppression.
• Loss and Leakage — Tangent of loss angle (tan δ) specified at 0.20 max (20°C, 120 Hz); measured leakage current listed as 910 µA for this part.
• Safety & Reliability — Improved safety features for handling abnormally excessive voltage and a pressure relief vent design to mitigate hazardous failure modes.
• Mechanical / Package — Large can snap‑in (radial) package, physical size φ35 × 35 mm (height × diameter in mm), supplied in tray packing for assembly efficiency.
• RoHS Compliance — Conforms to RoHS directive requirements as stated in the product documentation.

Typical Applications

• General‑purpose power filtering — Bulk smoothing and energy storage in power supplies and power conversion circuits that require a 420 V rated electrolytic solution.
• Voltage‑fluctuation environments — Designed for equipment operating where line voltage can vary; enhanced safety features and 105°C endurance help maintain performance under fluctuating conditions.
• High‑temperature enclosures — Suitable where sustained elevated ambient temperatures are expected, backed by a 2000‑hour endurance rating at 105°C.

Unique Advantages

• High voltage capability: The 420 V rating enables use in higher‑voltage DC buses and power stages without series stacking.
• Validated high‑temperature life: Endurance specified at 2000 hours at 105°C under rated ripple current demonstrates predictable long‑term behavior in hot environments.
• Dual‑frequency ripple handling: Specified ripple currents at 120 Hz and 100 kHz support both low‑frequency mains smoothing and higher‑frequency switching applications.
• Safety‑oriented design: Pressure relief vent and improved overvoltage safety characteristics reduce risk in abnormal conditions.
• Production‑friendly packaging: Tray packing and a snap‑in radial can package ease PCB assembly and handling in volume manufacturing.
• Clear electrical limits: Specified tan δ and leakage current values allow straightforward thermal and reliability margining in designs.
