LKX2G471MESC40

The LKX2G471MESC40 is a 470 µF, 400 V aluminum electrolytic capacitor in a snap‑in radial can package. It is part of Nichicon’s LKX series, optimized for audio equipment and switching power supplies and offered in tray packing for mass production.

Designed for demanding power applications, this polarized capacitor delivers high-voltage bulk capacitance with 2000 hours endurance at 105°C and RoHS compliance, making it suitable for general purpose high‑temperature power filtering and energy storage tasks.

Key Features

• Capacitance & Voltage — 470 µF nominal capacitance rated at 400 V with ±20% tolerance, providing substantial bulk energy storage for high‑voltage circuits.
• High‑Temperature Endurance — Rated lifetime of 2000 hours at 105°C with defined endurance limits for capacitance change, tan δ and leakage current, supporting sustained operation in elevated temperature environments.
• Ripple Current Performance — Specified ripple current of 1.68 A at 120 Hz and 2.402 A at 50 kHz. The LKX series includes frequency coefficients that increase allowable ripple current at higher frequencies (120 Hz = 1.00; 50 kHz ≈ 1.43 for 400–450 V range).
• Package & Mounting — Snap‑in, radial can package (φ35×40L) for secure through‑hole mounting; supplied in tray packing to support high‑volume assembly.
• Operating Range — Polarized capacitor with operating temperature range of −25°C to +105°C suitable for designs that require high‑temperature operation.
• Environmental Compliance — RoHS compliant, aligning with common environmental requirements for electronic components.

Typical Applications

• Audio Equipment — Bulk filtering and power supply smoothing; LKX series materials are selected to support superior acoustic sound.
• Switching Power Supplies — High‑voltage bulk capacitance and ripple handling for SMPS DC‑link and output filtering.
• General Purpose Power — High‑voltage, high‑capacitance applications requiring robust, polarized electrolytic capacitance in mass production builds.

Unique Advantages

• High Voltage Capability: 400 V rating enables use in high‑voltage power rails and DC bus applications without series stacking.
• Extended Thermal Endurance: 2000 hours at 105°C provides predictable performance over long periods at elevated temperatures, reducing maintenance and replacement frequency.
• Frequency‑Aware Ripple Handling: Documented ripple current ratings and series frequency coefficients allow designers to size capacitors accurately across switching frequencies.
• Production‑Friendly Packaging: Snap‑in radial can design with tray packing simplifies through‑hole assembly and supports high‑volume manufacturing workflows.
• Audio‑Focused Material Selection: LKX series selection of materials is intended to support high‑quality sound reproduction in audio applications.
• Regulatory Compliance: RoHS compliance supports adherence to environmental directives in product designs.
