LKSN2472MESB

The LKSN2472MESB is an aluminum electrolytic, snap-in terminal capacitor designed for audio equipment and general-purpose electronic applications. It provides 4700 µF capacitance at a 56 V rating in a compact φ30 × 30 mm can with snap-in mounting for secure board installation.

Engineered for demanding operating conditions, this polarized capacitor offers a wide operating temperature range and documented endurance for reliable performance in systems requiring bulk energy storage, filtering and ripple handling.

Key Features

• Capacitance & Voltage – 4700 µF (4.7 mF) nominal capacitance rated at 56 V, with a tolerance of ±20% at 120 Hz, 20°C.
• Compact Snap-in Package – Radial, can-style snap-in package sized φ30 × 30 mm (height seated max 1.181 inch) for board-mounted power applications.
• Ripple Current Capability – Rated ripple current of 2.9 A at 120 Hz, suitable for power-supply smoothing and decoupling under AC ripple conditions.
• Leakage Current – Specified leakage current of 1530 µA (measured after 5 minutes at rated voltage, 20°C), consistent with electrolytic performance expectations.
• Temperature & Endurance – Operating temperature range −40°C to +85°C with an endurance rating of 1000 hours at 85°C under applied rated voltage, meeting the series’ endurance criteria for capacitance, tan δ and leakage after restoration to 20°C.
• Compliance & Packaging – RoHS-compliant and supplied in tray packing for handling and assembly.
• Polarized Device – Designed as a polarized electrolytic capacitor; polarity should be observed during installation.

Typical Applications

• Audio Equipment – Bulk filtering and power-supply smoothing in audio amplifiers and related gear where the series is intended for audio applications.
• Power Supply Filtering – Energy storage and ripple reduction in DC power rails leveraging 4700 µF capacitance and 56 V rating.
• General-Purpose Electronics – Board-mounted decoupling and bulk capacitance for industrial and consumer equipment requiring a compact snap-in aluminum electrolytic.

Unique Advantages

• High Capacitance in a Compact Can – 4700 µF in a φ30 × 30 mm package delivers substantial bulk capacitance while minimizing board footprint.
• Secure Snap-in Mounting – Snap-in terminals provide a robust mechanical connection to PCBs, simplifying placement and securing the device in board-level power sections.
• Measured Ripple Handling – 2.9 A ripple current rating at 120 Hz supports effective AC ripple absorption in power-supply designs.
• Documented Endurance – Specified 1000-hour endurance at 85°C under rated voltage with defined limits for capacitance change, tan δ and leakage ensures predictable lifecycle behavior.
• Regulatory Compliance – RoHS-compliant construction supports restricted-substance requirements.
