LKX2D271MESY30

The LKX2D271MESY30 is an aluminum electrolytic capacitor in a snap‑in terminal style designed for audio equipment and switching power supply applications. It delivers 270 µF at 200 V in a compact φ20 × 30 mm can with radial snap‑in mounting and tray packing for production assembly.

Engineered for sustained operation up to 105°C, this RoHS‑compliant component combines endurance, measurable ripple handling and controlled dissipation factor to support power filtering and energy storage in general‑purpose electronic designs.

Key Features

• Capacitance & Voltage: 270 µF nominal capacitance at a rated voltage of 200 V with ±20% tolerance (measured at 120 Hz, 20°C).
• Thermal and Endurance: Rated for an operating temperature range of −40°C to +105°C with a specified endurance of 2000 hours at 105°C under DC bias plus rated ripple current.
• Ripple Current Performance: Low‑frequency ripple current of 990 mA at 120 Hz and high‑frequency ripple current of 1.485 A at 50 kHz, supporting a range of power filtering conditions.
• Electrical Losses: Tangent of loss angle (tan δ) of 0.15 at 20°C and 120 Hz for predictable dissipation behavior in audio and power circuits.
• Leakage Current: Specified leakage current of 690 µA after application of rated voltage (measurement conditions per product data).
• Package & Mounting: φ20 × 30 mm radial can with snap‑in terminals for secure chassis or PCB mounting; supplied in tray packing and available in mass production status.
• Environmental: Compliant with RoHS requirements.

Typical Applications

• Audio Equipment: Energy storage and power smoothing for amplifiers and audio power supplies where stable dissipation and endurance at 105°C are required.
• Switching Power Supplies: Bulk filtering and ripple current handling in switch‑mode power supplies for industrial and consumer electronics.
• General Purpose Power Filtering: Use as a long‑life filter capacitor in general purpose power systems that require snap‑in mounting and robust thermal endurance.

Unique Advantages

• High‑temperature endurance: 2000 hours rated life at 105°C provides predictable performance for designs exposed to elevated ambient temperatures.
• Measurable ripple capability: Specified ripple currents at both low and high frequencies (990 mA at 120 Hz and 1.485 A at 50 kHz) let designers evaluate filtering performance across real operating conditions.
• Controlled dissipation: tan δ = 0.15 at 20°C and 120 Hz supports consistent loss behavior important for audio and power stages.
• Compact snap‑in package: φ20 × 30 mm radial can with snap‑in terminals simplifies mechanical retention and assembly for production environments.
• RoHS compliant and production ready: Environmentally compliant construction and tray packing for streamlined sourcing and manufacturing.
