LKX2W181MESB30

The LKX2W181MESB30 is a snap‑in, radial aluminum electrolytic capacitor from Nichicon’s LKX series designed for audio equipment and switching power supply applications. It delivers 180 µF capacitance at a 450 V rating in a compact φ30 × 30 mm can, combining high voltage capability with long endurance and acoustic‑focused material selection.

Key attributes include a wide operating temperature range, robust ripple current handling at low and high frequencies, and a 2000‑hour endurance rating at 105 °C—characteristics targeted at designers who need reliable power filtering and energy storage in demanding electronic systems.

Key Features

• Capacitance & Voltage — 180 µF rated capacitance with a 450 V rated voltage and ±20% tolerance (measured at 120 Hz, 20 °C), suitable for high‑voltage DC link and smoothing roles.
• Low Loss Characteristics — Specified tan δ of 0.2 at 20 °C and 120 Hz for stable dissipation factor performance in audio and power applications.
• High Ripple Current Capability — 870 mA ripple current at 120 Hz and 1.244 A at 50 kHz, enabling effective handling of both low‑frequency and high‑frequency ripple in switchers and filter stages.
• Leakage Current — Low leakage current specified at 850 µA after voltage application, supporting low‑loss DC operation.
• Endurance — 2000 hours life at 105 °C under rated DC bias plus rated ripple current, with defined limits for capacitance change, tan δ, and leakage current after test.
• Package & Mounting — Radial, can‑style snap‑in terminal package (φ30 × 30 mm) for secure mechanical mounting and easy assembly; supplied in tray packing for production use.
• Operating Range & Polarization — Polarized capacitor rated for operation from −25 °C to +105 °C; designed and marked for correct polarity orientation.
• Compliance — RoHS compliant construction within the LKX series.

Typical Applications

• Audio Equipment — Used for power supply smoothing and energy storage in audio amplifiers and high‑fidelity circuits where the LKX series’ material selection supports acoustic performance.
• Switching Power Supplies — Suitable for DC link, bulk smoothing and ripple suppression in switch‑mode power supplies thanks to its 450 V rating and high ripple current capability.
• General Purpose Power Filtering — Employed wherever high‑voltage electrolytic bulk capacitance is required in industrial and consumer electronic power systems.

Unique Advantages

• High Voltage Handling: 450 V rating enables use in higher‑voltage DC rails and power conversion stages.
• Balanced Ripple Performance: Separate ripple current specs at 120 Hz and 50 kHz support both low‑frequency smoothing and high‑frequency decoupling needs.
• Long Endurance at Elevated Temperature: 2000 hours at 105 °C ensures stability of capacitance, dissipation factor and leakage under extended thermal stress.
• Audio‑Focused Materials: LKX series materials are selected to support superior acoustic sound quality in audio equipment applications.
• Production‑Ready Packaging: Tray packing and mass production status simplify integration into manufacturing workflows.
• Compact Snap‑In Form Factor: φ30 × 30 mm snap‑in can provides secure board mounting and straightforward mechanical installation.
