LKG1V472MESYAK

The LKG1V472MESYAK is a snap‑in aluminum electrolytic capacitor from Nichicon’s LKG series, designed specifically for audio equipment where high fidelity and reliable power smoothing are required. It provides 4700 µF capacitance at a 35 V rating with snap‑in radial mounting for secure through‑hole installation.

Key attributes include a wide operating temperature range of −40 °C to +85 °C, low‑frequency ripple handling of 2.2 A (120 Hz), and an endurance rating of 1000 hours at 85 °C. Note: this part is currently listed as End Of Life.

Key Features

• Capacitance and Voltage — 4700 µF nominal capacitance with a rated voltage of 35 V and capacitance tolerance of ±20% (measured at 120 Hz, 20 °C).
• Audio‑oriented design (LKG series) — The LKG series is specified “For Audio Use,” prioritizing tone quality and sound fidelity for high‑grade audio equipment; the part suffix "AK" corresponds to TYPE‑I (Gold Tune) grade in the LKG numbering system.
• Low‑frequency ripple capability — 2.2 A ripple current rating at 120 Hz supports power supply smoothing and bulk energy delivery in audio power stages.
• Loss characteristics — tan δ = 0.3 measured at 20 °C, 120 Hz, supporting stable performance in audio filtering applications.
• Leakage and endurance — Specified leakage current of 1210 µA and endurance of 1000 hours at 85 °C, with post‑endurance limits defined in the series specification.
• Form factor and mounting — Snap‑in radial (can, snap‑in) package for robust mechanical retention in PCB assemblies; physical size approximately φ20 × 35 mm (diameter × length), listed as 3.5 cm × 2.0 cm.
• Environmental compliance and packaging — RoHS compliant and supplied in tray packing for handling and assembly.

Typical Applications

• High‑grade audio amplifiers — Bulk filtering and smoothing in power supply rails to support consistent audio playback and reduced ripple in amplifier stages.
• Professional audio equipment — Energy storage and decoupling in mixers, preamps, and signal processing racks where stable supply filtering supports fidelity.
• Power supply modules for audio electronics — Supporting rectifier smoothing and hold‑up in audio power supplies with a 35 V system voltage requirement.

Unique Advantages

• Application‑focused electrical profile — 4700 µF at 35 V with 2.2 A ripple rating addresses the common bulk and smoothing needs of audio power stages.
• Audio grade selection (Gold Tune) — The TYPE‑I (AK) grade designation signals series‑level choices optimized for tone quality in the LKG family.
• Compact snap‑in packaging — Snap‑in radial can simplifies mechanical retention and through‑hole assembly for audio chassis and PCBs.
• Defined endurance and thermal range — 1000 hours at 85 °C and −40 °C to +85 °C operating range provide predictable lifetime behaviour under rated conditions.
• RoHS compliance — Meets RoHS requirements for environmentally restricted substances.
