LKG1V472MESZBK

The LKG1V472MESZBK is an aluminum electrolytic capacitor in the LKG series, configured with a snap-in terminal (radial can snap-in) and optimized for audio equipment. It provides 4.7 mF (4700 µF) capacitance at a 35 V rating with ±20% tolerance and is offered in a compact φ22 × 45 mm can.

This part targets audio applications that require high-capacitance filtering and audio-grade component characteristics. Key performance points include a rated ripple current of 2.7 A at 120 Hz, specified tan δ, a 1000-hour endurance at 85 °C, and RoHS compliance.

Key Features

• Capacitance & Voltage — 4.7 mF (4700 µF) nominal capacitance at a 35 V rated voltage with ±20% tolerance (measured at 120 Hz, 20 °C).
• Audio-Focused Design — Part of the LKG series described for audio use and engineered to prioritize high-fidelity sound quality for HD audio equipment.
• Snap-In Radial Can Package — Snap-in terminal mounting type in a radial can (φ22 × 45 mm), providing a robust mechanical connection for board-mounted power sections; marked with gold color lettering on a black sleeve.
• Thermal & Endurance Rating — Rated operating temperature range −40 °C to +85 °C with an endurance specification of 1000 hours at 85 °C (capacitance change within ±20%, tan δ up to 200% of initial value, leakage current within initial specified value after endurance).
• Ripple & Leakage Characteristics — Specified ripple current of 2.7 A at 120 Hz; listed leakage current value 1210 µA. The series datasheet also cites the leakage-current limit method (≤ 3√CV μA after 5 minutes at 20 °C).
• Regulatory & Packaging — RoHS compliant; supplied in tray packing. Note: this product is designated End of Life.

Typical Applications

• High‑fidelity audio equipment — Intended for use where component selection emphasizes tone quality and sound fidelity, as noted in the LKG series description.
• HD audio devices — Suited for designs that specify audio-grade components for improved tonal characteristics.
• Audio equipment assemblies with snap‑in requirements — Snap‑in terminal format supports assemblies that use radial can snap‑in capacitors for board mounting and mechanical retention.

Unique Advantages

• Large capacitance at system voltage — 4700 µF at 35 V provides significant bulk energy storage where high capacitance is required within a compact package.
• Audio-grade series engineering — The LKG family is described specifically for audio use and high-fidelity applications, supporting designers focused on tonal performance.
• Robust thermal endurance — 1000 hours rated life at 85 °C with defined post-endurance limits on capacitance, tan δ, and leakage current to help predict long-term behavior.
• High ripple capability — Rated ripple current of 2.7 A at 120 Hz to meet low-frequency ripple demands noted in the product data.
• Clear marking and compliance — Gold lettering on a black sleeve for easy identification, and RoHS compliance for regulatory alignment.
