LKX2W151MESA35

The LKX2W151MESA35 is a snap‑in terminal type aluminum electrolytic capacitor from Nichicon’s LKX series, specified for audio equipment and switching power supplies. It provides 150 µF capacitance at 450 V in a radial can snap‑in package (φ25 × 35 mm) with polarized terminals and tray packing for production assembly.

Designed for demanding power‑filtering and audio applications, this part offers high voltage capability, long endurance at elevated temperature, measurable ripple handling and controlled loss characteristics for reliable performance in industrial and audio electronics.

Key Features

• Electrical Capacity — 150 µF nominal capacitance with a tolerance of ±20% (measured at 120 Hz, 20°C), rated at 450 V DC for high‑voltage filtering and energy storage.
• Ripple Handling — Specified ripple current of 790 mA at 120 Hz and 1.13 A at 50 kHz, enabling effective smoothing in both low‑ and high‑frequency supply environments.
• Low Losses — Loss tangent (tanδ) of 0.2 at the stated measurement conditions, supporting lower dissipation in audio and power circuits.
• Leakage Current — Initial leakage current specified at 770 µA, suitable for designs that require predictable leakage behavior.
• Thermal and Endurance Rating — Operating temperature range from −25°C to +105°C with an endurance rating of 2000 hours at 105°C under rated voltage and ripple conditions.
• Package & Mounting — Radial can, snap‑in terminal construction (φ25 mm diameter × 35 mm length) for secure PCB mounting in production environments; delivered in tray packing for assembly line handling.
• RoHS Compliant — Conforms to RoHS directive requirements as stated for the LKX series.

Typical Applications

• Audio Equipment — Used for DC‑link and power‑supply filtering in audio amplifiers and related audio electronics where the LKX series materials and construction are targeted to support sound quality.
• Switching Power Supplies — Performs bulk smoothing and ripple suppression at high DC voltages in SMPS topologies.
• General Purpose Power Filtering — Suitable for industrial and consumer electronics requiring high‑voltage capacitance with long endurance at elevated temperatures.

Unique Advantages

• High Voltage Capability: 450 V rating enables use in higher‑voltage rails and reduces the need for series stacking of smaller capacitors.
• Defined Ripple Performance: Explicit ripple current ratings at 120 Hz (790 mA) and 50 kHz (1.13 A) allow designers to match the capacitor to expected ripple spectra and calculate thermal margins.
• Long Endurance at Elevated Temperature: 2000 hours at 105°C under rated conditions supports reliable lifetime in thermally stressed environments.
• Controlled Losses and Leakage: tanδ = 0.2 and leakage current = 770 µA provide predictable dissipation and leakage behavior for precision designs.
• Production‑Ready Packaging: Snap‑in radial can format with tray packing simplifies PCB assembly and mechanical retention for high‑volume manufacturing.
• RoHS Compliance: Meets RoHS requirements for regulatory alignment in many markets.
