LKX2D821MESA45

The LKX2D821MESA45 is a snap‑in aluminum electrolytic capacitor designed for audio equipment and switching power supplies. It provides 820 µF capacitance at a 200 V rating in a radial, snap‑in can (φ25 × 45 mm) optimized for power filtering and energy storage in demanding environments.

Engineered for durability, this component is rated for 2000 hours at 105°C and offers measurable ripple handling and leakage performance suited to high‑temperature, high‑stress designs where long life and stable electrical behavior matter.

Key Features

• Capacitance & Voltage — 820 µF nominal capacitance with a 200 V rated voltage and capacitance tolerance of ±20% (120 Hz, 20°C).
• Thermal & Lifetime Performance — Rated operating temperature range of −40°C to +105°C with an endurance of 2000 hours at 105°C under DC bias plus rated ripple current.
• Ripple Current Capability — Low‑frequency ripple current of 2.04 A (120 Hz) and high‑frequency ripple current of 3.06 A (50 kHz), enabling effective smoothing in power stages.
• Loss and Leakage — Specified dissipation factor (tanδ) of 0.15 and measured leakage current of 1210 µA, allowing engineers to account for dissipation and standby losses.
• Mechanical & Mounting — Radial, snap‑in can package (φ25 × 45 mm) for secure board mounting and efficient placement in power assemblies; packaged in tray packing for handling.
• Compliance — RoHS‑compliant construction and offered as a mass production part in Nichicon’s LKX series.

Typical Applications

• Audio Equipment — Bulk power smoothing and reservoir capacitance in audio power supplies where materials were selected for acoustic performance.
• Switching Power Supplies — Output filtering and energy storage in switch‑mode power supplies requiring high voltage handling and sustained ripple endurance.
• General‑Purpose Power Filtering — Power rail decoupling and bulk filtering across industrial and consumer electronics that operate within −40°C to +105°C.

Unique Advantages

• High‑temperature endurance: 2000 hours at 105°C ensures predictable capacitance and leakage behavior after prolonged exposure to elevated temperatures.
• Designed for audio quality: Materials selection in the LKX series targets improved acoustic performance for audio equipment applications.
• Robust ripple handling: Defined low‑ and high‑frequency ripple current ratings (2.04 A at 120 Hz, 3.06 A at 50 kHz) allow precise thermal and lifetime planning in power designs.
• Practical mechanical form factor: φ25 × 45 mm snap‑in can provides a compact, board‑mountable solution for high‑capacitance, high‑voltage needs.
• Clear electrical parameters: Specified tanδ (0.15) and measured leakage current (1210 µA) enable accurate loss and standby current budgeting.
• RoHS compliant and production ready: Mass production status and RoHS compliance support volume manufacturing and regulatory needs.
