LAK2D271MELZ30

The LAK2D271MELZ30 is an aluminum electrolytic, snap‑in terminal capacitor in a radial can package, offering 270 µF capacitance at a 200 V rating. It is designed for general‑purpose use in equipment exposed to fluctuating voltages and demanding ripple conditions.

Key value comes from series-level endurance and safety features: the LAK family withstands 2000 hours of rated ripple current at 105 °C, includes improved safety measures for abnormal overvoltage, and complies with RoHS (2011/65/EU, (EU)2015/863).

Key Features

• Electrical characteristics — 270 µF nominal capacitance with ±20% tolerance and a 200 V rated voltage, polarized for DC applications.
• High‑temperature endurance — Rated for operation from −25 °C to +105 °C and specified to withstand 2000 hours of rated ripple current at 105 °C.
• Ripple current capability — Series ripple ratings include 900 mA at 120 Hz and 1.08 A at 10 kHz for this size class, supporting high ripple environments.
• Leakage and dissipation — Leakage current is specified by I ≤ 3√(C·V) (µA) after 5 minutes at 20 °C; tangent of loss angle (tan δ) max 0.20 at 120 Hz, 20 °C.
• Safety features — Designed with a pressure relief vent and verified safety performance under series test conditions to avoid flames, ignition, or dispersion under abnormal voltage stress.
• Mechanical / package — Snap‑in radial can package, nominal dimensions 22 mm diameter × 30 mm length, suitable for secure chassis or board mounting in filter banks.
• Environmental compliance — RoHS compliant (2011/65/EU, (EU)2015/863).

Typical Applications

• Industrial power equipment — Smoothing and ripple handling in equipment operating in voltage‑fluctuating areas where extended ripple endurance and high temperature capability are required.
• Switch‑mode power supplies — DC bus and output filtering for 200 V systems benefiting from the capacitor’s 270 µF value and rated ripple current.
• Chassis‑mounted filter banks — Snap‑in radial package enables straightforward installation for bulk capacitance in power conversion and conditioning systems.
• General‑purpose electronics — Applications that need polarized, high‑voltage aluminum electrolytic capacitance with RoHS compliance and verified endurance at elevated temperature.

Unique Advantages

• Extended ripple endurance: Specified to withstand 2000 hours of rated ripple current at 105 °C, enabling longer service life in high‑stress environments.
• High‑voltage capability in a compact can: 270 µF at 200 V in a 22 mm × 30 mm snap‑in package delivers significant capacitance density for constrained spaces.
• Measured ripple performance: Ripple current ratings (900 mA @120 Hz, 1.08 A @10 kHz) support both low‑ and high‑frequency ripple conditions.
• Safety‑oriented design: Pressure relief vent and series safety test conditions reduce risk under abnormal overvoltage events.
• Broad operating range: −25 °C to +105 °C operation supports deployment in environments with elevated ambient temperatures.
• RoHS compliant: Meets current RoHS directives for use in regulated markets.
