LKS1J472MESA

The LKS1J472MESA is a snap‑in, polarized aluminum electrolytic capacitor in Nichicon’s LKS series designed for audio equipment and general‑purpose electronic applications. It delivers 4.7 mF capacitance at a 63 V rated voltage in a compact snap‑in can package.

Engineered for board‑level power filtering and tone‑quality improvement when replacing smaller standard capacitors, this part combines high bulk capacitance, 3 A ripple handling (120 Hz), and RoHS compliance for reliable operation across a wide temperature range.

Key Features

• Electrical Capacity — 4.7 mF (4700 μF) rated capacitance with ±20% tolerance at 120 Hz, 20°C to support bulk energy storage and decoupling in power rails.
• Rated Voltage — 63 V DC rated voltage suitable for higher‑voltage audio and general‑purpose power circuits.
• Ripple Handling — Rated ripple current of 3 A at 120 Hz, enabling effective smoothing of low‑frequency rectified supplies.
• Polarized Aluminum Electrolyte — Polarized design for typical power and audio filtering topologies requiring large capacitance.
• Mounting & Package — Snap‑in terminal, radial can package for secure board retention and straightforward insertion in power supply and amp modules. Size: L: 4 × D: 2.5 cm.
• Temperature & Endurance — Operating temperature range −40°C to +85°C; endurance specified as 1000 hours at 85°C with rated voltage applied, with limits on capacitance change, tan δ, and leakage current defined by the series specification.
• Leakage Current Specification — Series leakage current requirement: after 5 minutes at rated voltage and 20°C, leakage current not more than 3√(C·V) μA (C in μF, V in V).
• Regulatory — Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Audio Equipment — Bulk decoupling and power supply smoothing in amplifiers and audio signal chains; specified for tone‑quality improvement when used as an upgrade from smaller standard capacitors.
• Power Supply Filtering — Energy storage and ripple suppression on rectified rails and regulator inputs where high capacitance and 63 V rating are required.
• General‑Purpose Electronics — Suitable for a wide range of electronic modules that require polarized aluminum electrolytic capacitors with snap‑in mounting.

Unique Advantages

• High Bulk Capacitance: 4.7 mF provides substantial energy storage for smoothing and transient support in power rails.
• High Voltage Margin: 63 V rating allows use in higher‑voltage circuits compared with lower‑voltage electrolytics.
• Robust Ripple Capability: 3 A ripple current (120 Hz) supports sustained AC loading typical in rectified audio and power supplies.
• Snap‑in, Radial Can Packaging: Snap‑in terminals deliver secure board retention and reliable mechanical mounting for cabinet or chassis installations.
• Endurance‑Defined Reliability: 1000 hours at 85°C endurance specification provides quantifiable performance expectations for elevated‑temperature operation.
• RoHS Compliant: Conforms to current RoHS directives for regulatory alignment in commercial electronics.
