LKX2E102MESB45

The LKX2E102MESB45 is a 1000 µF, 250 V polarized aluminum electrolytic capacitor in a snap‑in can package, optimized for audio equipment and switching power supplies. It is part of Nichicon’s LKX series designed for 105°C operation with material selection intended to support superior acoustic performance.

Designed for general‑purpose power filtering and bulk energy storage, this snap‑in radial can provides high ripple current capability and long endurance for demanding thermal and electrical environments.

Key Features

• Capacitance and Voltage: 1000 µF nominal capacitance at a rated voltage of 250 V, with a tolerance of ±20% (–20%~20%).
• High‑temperature endurance: Rated for operation from –40°C to +105°C with a life/endurance of 2000 hours at 105°C under rated conditions.
• Ripple current capability: Low‑frequency ripple current 2.2 A at 120 Hz and high‑frequency ripple current 3.3 A at 50 kHz, supporting smoothing and decoupling in power supplies.
• Loss characteristics: Tangent of loss angle (tan δ) 0.15 measured at 20°C, 120 Hz (DF measurement condition).
• Leakage current: Specified leakage current of 1500 µA after standard application of rated voltage.
• Package and mounting: Snap‑in radial can (φ30 × 45 mm length) for secure chassis or PCB mounting; supplied in tray packing for handling and assembly.
• Material selection and RoHS compliance: Built from materials selected to support acoustic performance and compliant with RoHS (2011/65/EU, (EU)2015/863).
• Polarized design: Polarized aluminum electrolytic construction suitable for DC power applications.

Typical Applications

• Audio equipment: Bulk energy storage and power supply smoothing in amplifiers and audio circuits where material selection supports acoustic performance.
• Switching power supplies: Input/output smoothing and ripple absorption in SMPS modules requiring 250 V rating and elevated temperature endurance.
• General power filtering: Decoupling and bulk capacitance for industrial and consumer power systems needing high ripple handling and long‑term stability.

Unique Advantages

• High ripple handling: 2.2 A at 120 Hz and 3.3 A at 50 kHz allow the capacitor to manage both low‑ and high‑frequency ripple in power circuits.
• 105°C rated endurance: 2000 hours at 105°C provides predictable performance in sustained high‑temperature applications.
• Acoustic‑focused materials: Components and materials chosen to support superior sound quality in audio applications.
• Compact snap‑in packaging: φ30 × 45 mm radial can with snap‑in terminals enables robust mounting and straightforward integration into assemblies.
• Clear loss specification: tan δ of 0.15 (20°C, 120 Hz) gives a measurable indicator of dissipation for design tradeoffs.
• Regulatory compliance: RoHS compliant to applicable directives for environmental conformity.
