LKX2D102MESA50

The LKX2D102MESA50 from Nichicon is a snap‑in aluminum electrolytic capacitor in the LKX series, specified at 1000 µF and 200 V. It is designed for audio equipment and switching power supply applications that require high ripple handling and robust thermal endurance.

Key attributes include snap‑in radial can packaging (φ25 × 50 mm), rated operation to 105°C, and a 2000‑hour endurance at 105°C—providing practical durability and assembly convenience for board‑level power and audio circuits.

Key Features

• Capacitance & Voltage — 1000 µF nominal capacitance at a 200 V rated voltage, with ±20% tolerance for bulk energy storage and filtering.
• Mounting & Package — Snap‑in radial can (φ25 × 50 mm) for secure board installation and streamlined assembly; tray packing for unit handling.
• Thermal Endurance — Rated for operation from −40°C to 105°C with a specified life of 2000 hours at 105°C under rated ripple and DC bias.
• Ripple Current Capability — Rated ripple current of 2.3 A at 120 Hz and 3.45 A at high frequency (specified at 50 kHz), supporting higher AC stress tolerance in power circuits.
• Low Loss for Audio — Specified tan δ of 0.15 (measurement at 120 Hz, 20°C), selected materials and construction aimed at audio equipment use.
• Leakage Current — Initial leakage current specified at 1,340 µA (after 5 minutes at rated voltage, 20°C).
• Polarized — Electrolytic (polar) capacitor suited for DC power rail applications.
• Compliance — RoHS compliant.

Typical Applications

• Audio Equipment — Bulk smoothing and power‑supply decoupling where low loss (tan δ) and stable performance at 105°C contribute to consistent audio performance.
• Switching Power Supplies — Bulk energy storage and ripple suppression on 200 V rails, leveraging the capacitor’s high ripple current ratings and endurance at elevated temperature.
• General Purpose Power Filtering — DC bus smoothing and transient energy buffering in industrial and commercial power circuits requiring a polarized, high‑capacitance snap‑in part.

Unique Advantages

• High Ripple Handling: 2.3 A at 120 Hz and 3.45 A at high frequency reduce the need for parallel parts when addressing AC ripple on DC rails.
• 105°C Endurance: 2000 hours at 105°C under rated conditions provides predictable long‑term performance in hot environments.
• Audio‑Focused Characteristics: tan δ specified at 0.15 and material selection targeted for audio applications help maintain low loss and stable behavior relevant to sound quality.
• Snap‑In Packaging: φ25 × 50 mm radial can with snap‑in terminals enables secure board mounting and efficient assembly for through‑hole power modules.
• Regulatory Compatibility: RoHS compliance supports use in regulated markets and product lines.
• Tray Packing for Production: Tray packing format facilitates handling during manufacturing and inventory management.
