LKX2E471MESZ45

The LKX2E471MESZ45 is a Nichicon LKX series snap-in aluminum electrolytic capacitor rated at 470 µF and 250 V. Designed for power filtering in applications where robust ripple handling and elevated operating temperature are required, it combines snap-in mounting with a radial can package for secure board installation.

Targeted uses include audio equipment and switching power supplies, and the part leverages materials selected to support superior acoustic sound while meeting general-purpose power electronics requirements.

Key Features

• Electrical Performance — 470 µF capacitance with ±20% tolerance and 250 V rated voltage for bulk energy storage and smoothing in power rails.
• Ripple Current Handling — Rated ripple current of 1.4 A at 120 Hz and 2.1 A at 50 kHz; frequency coefficients in the datasheet allow designers to scale ripple ratings across frequencies.
• Thermal and Lifetime — Operational temperature range from −40°C to +105°C with an endurance specification of 2000 hours at 105°C under rated conditions.
• Package & Mounting — Snap-in radial can package (L: 4.5 × D: 2.2 cm) for reliable, serviceable board mounting in power assemblies.
• Reliability Characteristics — Endurance and shelf-life characteristics defined: capacitance change and leakage limits after 2000 hours at 105°C and after 1000 hours shelf storage at 105°C with prescribed recovery treatment.
• Compliance & Marking — RoHS compliant; capacitors are marked with gold lettering on a black sleeve as specified in the datasheet.
• Polarized Design — Polarized electrolytic construction for use in DC bulk and smoothing applications.

Typical Applications

• Audio Equipment — Bulk filtering and power smoothing in audio power supplies where materials are chosen to support acoustic performance.
• Switching Power Supplies — Output and intermediate bus filtering where high ripple currents and elevated temperature endurance are required.
• General-Purpose Power Electronics — Energy storage and decoupling in industrial and commercial power systems that require snap-in mounting and robust thermal performance.

Unique Advantages

• High-voltage capability: 250 V rating enables use on higher-voltage rails without additional series stacking.
• Frequency-aware ripple ratings: Published ripple current values at 120 Hz and 50 kHz, plus frequency coefficients, help engineers size capacitors across switching and audio frequency domains.
• Designed for elevated temperatures: Specified operation to +105°C and a 2000-hour endurance at that temperature provide predictable long-term performance in hot enclosures.
• Secure snap-in mounting: Radial snap-in can package and defined dimensions (L: 4.5 × D: 2.2 cm) simplify PCB retention and mechanical reliability in power modules.
• RoHS compliant: Meets environmental requirements for materials and manufacturing processes.
• Audio-focused material selection: Materials selected to achieve superior acoustic sound make this part suitable where audible performance is a consideration.
