LKG1E472MESABK

The LKG1E472MESABK is a snap‑in terminal aluminum electrolytic capacitor from Nichicon's LKG series, specified for audio equipment. It is a 4.7 mF (4700 µF), 25 V polarized capacitor in a radial snap‑in can intended for high‑grade audio applications.

Designed and specified for audio use, this part combines high capacitance in a compact φ25 × 30 mm can with performance-focused electrical characteristics (low‑frequency ripple handling, defined loss tangent, and rated endurance) appropriate for designers of high‑fidelity audio systems.

Key Features

• Capacitance & Tolerance — 4700 µF (4.7 mF) with ±20% tolerance at 120 Hz, 20°C, offering bulk energy storage for audio circuits.
• Rated Voltage — 25 V working voltage suitable for common audio power rails.
• Audio‑focused LKG Series (TYPE‑II) — Part number code includes BK indicating TYPE‑II grade in the LKG family, a grade positioned for audio applications.
• Loss Tangent (tan δ) — tan δ = 0.3 measured at 20°C, 120 Hz, enabling predictable frequency‑dependent losses in design calculations.
• Low‑Frequency Ripple Handling — Rated low‑frequency ripple current of 2.25 A at 120 Hz to support audio power supply filtering under load.
• Leakage Current — Specified leakage current of 1020 µA, useful when budgeting standby and quiescent currents.
• Endurance & Temperature Range — Specified lifetime of 1000 hours at 85°C and operating range −40°C to +85°C for defined long‑term behavior under rated stress.
• Package & Mounting — Radial, snap‑in can (tray packed) for secure chassis or PCB mounting in audio equipment assemblies.
• RoHS Compliant — Meets RoHS directive requirements as stated in product information.

Typical Applications

• High‑Fidelity Audio Equipment — Suited for use in high‑grade audio systems where the LKG series is specified to prioritize sound quality.
• Audio Power Supply Filtering — Bulk energy storage and 2.25 A ripple current rating support smoothing and decoupling on audio power rails.
• HD Audio Systems — Intended for use in systems that require components selected for audio performance and tonal quality.

Unique Advantages

• Audio‑focused Grade: The BK code identifies this unit as TYPE‑II within the LKG family, aligning the part with the series' audio performance objectives.
• High Capacitance in Compact Can: 4700 µF in a φ25 × 30 mm package provides substantial energy density for designs constrained by board space or enclosure volume.
• Defined AC Performance: Specified tan δ and ripple current at 120 Hz allow predictable AC loss and thermal management planning in audio power stages.
• Temperature and Endurance Specification: 1000 hours at 85°C and an operating range of −40°C to +85°C give explicit limits for long‑term reliability planning.
• RoHS Compliance: Declared RoHS compliance supports regulatory requirements in product development and manufacturing.
