LKG1E472MESBCK

The LKG1E472MESBCK is an aluminum electrolytic, snap‑in terminal capacitor in the Nichicon LKG series, rated 4700 µF at 25 V. It is built for audio use and designed to prioritize high‑fidelity sound in high‑grade and HD audio equipment.

As a snap‑in, radial can component, this part delivers a combination of bulk capacitance, a robust mounting style, and electrical characteristics tuned for audio applications where stable performance across temperature and time is required.

Key Features

• Capacitance & Voltage — 4700 µF nominal capacitance at a rated voltage of 25 V, with a capacitance tolerance of ±20% (measured at 120 Hz, 20 °C).
• Audio‑focused LKG Series Grades — The LKG series provides TYPE‑I, TYPE‑II and TYPE‑III tone‑quality grades (TYPE‑I: low profile high tone quality; TYPE‑II: center grade electrode foil; TYPE‑III: highest tone quality with gold‑plated terminals) to meet varying HD audio requirements.
• Mounting & Package — Snap‑in terminal, radial can (φ30 × 40L dimension and L: 4 × D: 3 cm reported), suitable for secure PCB installation in equipment chassis designed for snap‑in capacitors.
• Operating Temperature & Endurance — Rated for −40 °C to +85 °C. Endurance: specified to meet performance after 1000 hours at 85 °C with rated voltage applied.
• Ripple Current — Rated ripple current of 3.25 A at 120 Hz, supporting audio‑grade dynamic load conditions at the specified measurement frequency.
• Polarized Electrolytic Construction — Polarized design typical of aluminum electrolytic capacitors; observe polarity in application.
• Marking & Compliance — Marked with gold‑color letters on a black sleeve and compliant with the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• High‑grade audio equipment — Intended for use in systems that prioritize high fidelity sound quality and tone accuracy.
• HD Audio devices — Suited to audio products and subsystems where the LKG series’ tone‑quality grades are specified.
• Professional audio systems — Appropriate for professional and studio equipment that reference the LKG series for audio performance.

Unique Advantages

• Designed for audio fidelity — Series‑level design and grade options emphasize tone quality to support high‑fidelity and HD audio applications.
• Robust snap‑in mounting — Radial, snap‑in can package delivers a secure mechanical connection for equipment chassis and PCB installations.
• Temperature stability and endurance — Rated from −40 °C to +85 °C with a 1000‑hour endurance specification at 85 °C, providing predictable long‑term behavior under specified conditions.
• Measured ripple capability — 3.25 A ripple current rating at 120 Hz aligns with AC test conditions typically used for audio‑oriented ripple specifications.
• Regulatory compliance — RoHS compliance supports environmentally regulated production and procurement requirements.
