LKX2G151MESA30

The LKX2G151MESA30 is a 150 µF, 400 V aluminum electrolytic capacitor in a snap‑in radial can package. It is part of Nichicon’s LKX series designed for use in audio equipment and switching power supplies and is intended for general‑purpose power filtering and energy storage in higher‑voltage designs.

Engineered for long endurance at elevated temperature, the capacitor provides a combination of high voltage rating, defined ripple handling and a 105 °C maximum operating temperature to support reliable power rail smoothing and reservoir applications.

Key Features

• Capacitance & Voltage: 150 µF rated capacitance at 400 V for energy storage and DC bus smoothing in high‑voltage circuits.
• High‑temperature Endurance: Rated for operation to 105 °C with a specified lifetime of 2000 hours at 105 °C under DC bias plus rated ripple current.
• Ripple Current Capability: Defined ripple current handling of 850 mA at 120 Hz and 1.216 A at 50 kHz to support switching power supply and high‑frequency applications.
• Loss Characteristic: tan δ of 0.15 (measurement at 120 Hz, 20 °C), enabling predictable performance for AC ripple and audio‑sensitive circuits.
• Package & Mounting: Radial, snap‑in can (φ25 × 30 mm) designed for secure snap‑in board mounting and compact footprint.
• Polarized Design: Polar electrolytic construction for DC applications requiring large capacitance in a compact package.
• RoHS Compliant: Conforms to RoHS requirements.

Typical Applications

• Audio Equipment: Bulk filtering and reservoir capacitance in audio power supplies; series materials are selected to support high‑quality sound.
• Switching Power Supplies: DC bus smoothing and output filtering where 400 V rated capacitance and defined ripple handling are required.
• Industrial Power Rails: Energy storage and decoupling for high‑voltage control and power modules operating up to 105 °C.
• General Purpose Power Electronics: Applications requiring compact, high‑voltage electrolytic capacitance with snap‑in mounting for reliable assembly.

Unique Advantages

• High‑Voltage Capability: 400 V rating enables use in higher‑voltage DC bus and power supply stages without series stacking.
• Defined Ripple Performance: Specified ripple currents at 120 Hz and 50 kHz help engineers size capacitors accurately for both low‑ and high‑frequency ripple conditions.
• Temperature‑Proven Endurance: 2000‑hour rating at 105 °C provides a quantifiable reliability metric for designs that operate at elevated temperatures.
• Compact Snap‑In Package: φ25 × 30 mm radial can with snap‑in terminals simplifies board mounting while saving PCB space.
• Predictable Loss Tangent: tan δ = 0.15 (120 Hz, 20 °C) supports designers in estimating AC dissipation and thermal behavior.
• RoHS Compliance: Meets RoHS directive requirements for regulatory and environmental compatibility.
