LKX2D122MESC35

The LKX2D122MESC35 is an aluminum electrolytic, snap‑in terminal capacitor offering 1,200 µF capacitance at a 200 V rating. It is designed for audio equipment and switching power supply applications where high ripple handling and high‑temperature endurance are required.

Built to operate from −40°C to +105°C and rated for 2,000 hours at 105°C, this RoHS‑compliant radial can provides low loss (tanδ 0.15 at 20°C, 120 Hz), high ripple current capability, and tray packing suitable for mass production supply chains.

Key Features

• Capacitance & Voltage: 1,200 µF at 200 V for bulk energy storage and smoothing in high‑voltage circuits.
• Snap‑In Radial Package: Robust snap‑in can mounting (φ35 × 35 mm) designed for secure mechanical and electrical connection in power assemblies.
• High‑Temperature Endurance: Rated for 2,000 hours at 105°C, enabling extended operation under elevated thermal stress.
• Wide Operating Range: Operational from −40°C to +105°C to support a broad set of environmental conditions.
• Low Loss (tanδ): tanδ = 0.15 (20°C, 120 Hz) for reduced dissipation and stable performance in audio and power filtering.
• High Ripple Current Capability: 2.65 A at 120 Hz (low frequency) and 3.975 A at 50 kHz (high frequency) for demanding ripple environments.
• Leakage Current: Specified leakage current of 1,460 µA after rated voltage application, allowing predictable bias behavior.
• Capacitance Tolerance: ±20% to align with common design margins for bulk filtering and decoupling.
• Compliance & Packaging: RoHS‑compliant and supplied in tray packing for production workflows.

Typical Applications

• Audio Equipment: Bulk smoothing and power reservoir duties in audio amplifiers and signal chains where low loss and acoustic‑friendly materials are specified.
• Switching Power Supplies: Input/output filtering and energy storage to handle high ripple currents and sustained thermal load in SMPS designs.
• General Purpose Power Filtering: DC bus decoupling and bulk capacitance in industrial and consumer power systems requiring a 200 V rating.

Unique Advantages

• Designed for High‑Temperature Reliability: 2,000‑hour rating at 105°C supports long life in thermally demanding assemblies.
• Strong Ripple Handling: High low‑ and high‑frequency ripple current ratings reduce heating and improve reliability under dynamic load conditions.
• Low Dissipation for Audio Performance: Specified tanδ of 0.15 at 120 Hz helps minimize loss and preserve signal quality in audio power stages.
• Robust Mechanical Mounting: Snap‑in radial can simplifies PCB retention and mechanical stability for power module designs.
• Production‑Ready Packaging: Tray packing and mass production status aid efficient BOM fulfillment and assembly throughput.
• Regulatory Compliance: RoHS‑compliant construction supports environmental requirements for modern electronics manufacturing.
