LKG1H472MESZAK

The LKG1H472MESZAK is an aluminum electrolytic, snap‑in terminal capacitor from Nichicon's LKG series, specified at 4,700 µF and 50 V with ±20% tolerance. It is designed for high‑grade audio equipment where priority is placed on high‑fidelity sound quality.

Packaged in a radial can with snap‑in terminals and a compact 22 mm diameter by 45 mm length footprint, this part suits power‑supply smoothing and energy‑storage roles in audio amplifiers, studio equipment, and other HD audio applications. It is RoHS‑compliant and rated for operation from −40 °C to +85 °C.

Key Features

• Capacitance & Voltage: 4,700 µF nominal capacitance at a 50 V rated voltage with ±20% tolerance, providing substantial bulk capacitance for power‑supply filtering and reservoir applications.
• Audio‑oriented formulation: Part of the LKG series engineered for high‑grade audio equipment; the series includes low‑profile and high‑tone quality electrolyte options intended to prioritize sound quality.
• Snap‑in radial can package: Snap‑in terminal mounting simplifies assembly and mechanical retention for chassis or PCB installations while maintaining a compact can form factor (Ø22 mm × 45 mm).
• Low loss (tan δ): Specified tan δ of 0.3 (measured at 120 Hz, 20 °C) to characterize dissipation and performance relevant to audio circuits.
• Temperature and lifetime rating: Rated for −40 °C to +85 °C operation with an endurance of 1,000 hours at 85 °C under rated voltage conditions.
• Ripple current capability: Rated ripple current of 2.6 A at 120 Hz, supporting dynamic supply currents typical in audio power stages.
• Environmental compliance: Compliant with RoHS directives (2011/65/EU and (EU)2015/863).
• Polarized design: Standard electrolytic polarization for DC filtering and reservoir applications.

Typical Applications

• High‑fidelity audio amplifiers: Bulk filtering and reservoir capacitance to stabilize power rails and support dynamic output stages in consumer and professional amplifiers.
• Studio and broadcast equipment: Power‑supply smoothing for preamplifiers, mixers, and signal‑chain electronics where audio quality is a priority.
• High‑end consumer audio devices: Energy storage and decoupling in DAC power supplies and analog front‑end circuits to help maintain signal integrity.
• Power modules for audio subsystems: Local energy buffering for motor drivers, subwoofer amplifiers, and other modules with significant transient current demands.

Unique Advantages

• Audio‑focused design: Part of the LKG series tailored for sound quality, making it suitable for designs where tonal characteristics matter.
• High capacitance in a compact can: 4,700 µF in a 22 mm diameter can enables substantial capacitance without large board area.
• Robust ripple handling: 2.6 A ripple current rating at 120 Hz supports the dynamic current profiles of audio power supplies.
• Wide operating temperature window: −40 °C to +85 °C operation with a 1,000‑hour endurance at 85 °C provides predictable life under elevated temperature stress.
• Assembly friendly snap‑in terminals: Snap‑in mounting reduces assembly time and provides solid mechanical retention for chassis or PCB installs.
• Regulatory compliance: RoHS compliance supports use in products requiring restricted‑substance conformity.
