LKS1E472MESA

The LKS1E472MESA is a snap-in terminal aluminum electrolytic capacitor from Nichicon's LKS series, optimized for audio equipment and general-purpose electronic use. It provides 4.7 mF of capacitance at a 25 V rating in a compact snap-in radial can package.

Designed as a smaller-sized option within the LKS family, this part targets applications where compact high-capacitance filtering and an improvement in tone quality are desirable. The device is RoHS compliant and built to the electrical and endurance characteristics published for the LKS series.

Key Features

• Electrical Performance – 4.7 mF (4700 μF) capacitance at a 25 V rated voltage with ±20% tolerance (120 Hz, 20°C). The capacitor is polarized.
• Leakage and Loss Characteristics – Leakage current specification: after 5 minutes' application of rated voltage at 20°C, leakage current is not more than 3√CV (μA) [C: Rated Capacitance (μF), V: Voltage (V)]. Specified tan δ is 0.30 (measured at 120 Hz, 20°C) for this part.
• Ripple Handling – Rated ripple current of 1.5 A (Arms) at 120 Hz, suitable for mains-frequency smoothing and power-supply decoupling tasks in consumer and audio electronics.
• Package & Mounting – Snap-in terminal, radial can package. Typical package dimension for this part is 25 × 20 mm (φD × L), offering a compact footprint for high-capacitance requirements.
• Thermal Range & Endurance – Operating temperature range is −40°C to +85°C. Endurance: rated voltage applied for 1000 hours at 85°C with specified recovery limits for capacitance, tan δ and leakage current.
• Environmental Compliance – Compliant to the RoHS directive (2011/65/EU, (EU)2015/863).
• Audio-focused Design – Part of the LKS family described as smaller and providing higher tone quality than the LKG TYPE‑1 grade, intended to deliver an audible improvement when replacing standard small capacitors in audio circuits.

Typical Applications

• Audio Equipment – Bulk filtering and power supply smoothing in amplifiers and audio power stages where improved tone quality is desired by replacing smaller standard capacitors.
• Consumer Electronics – Power rail decoupling and smoothing in compact consumer designs that require high capacitance in a small footprint.
• General Purpose Electronics – Energy storage and filtering in a wide range of electronic equipment using snap-in radial mounting for easy panel or PCB integration.

Unique Advantages

• High Capacitance in a Compact Package: 4.7 mF of capacitance provided in a 25 × 20 mm radial can, enabling space-efficient designs that still require large capacitance values.
• Designed for Improved Audio Tone: LKS series positioning indicates a smaller, higher-tone-quality option compared to LKG TYPE‑1 grade, useful when upgrading audio circuits.
• Robust Ripple Handling: 1.5 A ripple current rating at 120 Hz reduces stress on upstream regulators and helps maintain stable filtering under load.
• Endurance under Elevated Temperature: Rated for 1000 hours at 85°C, with recovery criteria defined for capacitance, tan δ and leakage current.
• RoHS Compliant: Meets RoHS directives cited in the product information, supporting regulatory compliance for electronic assemblies.
