LKS1J472MESC

The LKS1J472MESC is a snap-in terminal aluminum electrolytic capacitor from Nichicon's LKS series, designed for audio equipment and general-purpose electronic applications. It delivers 4.7 mF capacitance at a 63 V rating in a compact radial can with snap-in mounting, offering a space-conscious option for power filtering and decoupling.

Engineered for extended operation across a wide ambient range and compliant with RoHS (2011/65/EU, (EU)2015/863), this part targets designs that benefit from a smaller-sized capacitor and documented tone-quality improvement when replacing small standard products.

Key Features

• Core electrical characteristics: 4.7 mF capacitance, 63 V rated voltage, polarized design with ±20% tolerance (measured at 120 Hz, 20°C).
• Package and mounting: Radial, snap-in can package for robust board mounting; physical dimensions L: 2.5 × D: 3.5 cm with a seated height maximum of 2.5 cm.
• Temperature and lifetime: Operates from −40°C to +85°C with a specified endurance of 1000 hours at 85°C under rated voltage; capacitance change is specified to remain within ±20% after endurance testing.
• Ripple and loss characteristics: Rated low-frequency ripple current of 3 A at 120 Hz; tan δ and impedance performance are measured at 120 Hz per datasheet specifications.
• Leakage specification: Leakage current defined as not more than 3√(C·V) μA after 5 minutes at 20°C (C = rated capacitance in μF, V = voltage in V).
• Audio-focused design note: Datasheet specifies this LKS grade as smaller and offering improved tone quality compared with LKG TYPE-1 grade when used as a replacement for small standard products.
• Environmental compliance: RoHS compliant (2011/65/EU, (EU)2015/863).

Typical Applications

• Audio equipment: Power supply filtering and decoupling in audio amplifiers and consumer audio devices where replacement of smaller standard capacitors can improve tone quality.
• General-purpose power filtering: Bulk capacitance for DC power rails and smoothing in a wide range of electronics due to 4.7 mF capacitance and 63 V rating.
• Component upgrades and retrofits: Direct replacement or upgrade in designs seeking a smaller-sized snap-in capacitor with documented tonal improvement relative to certain standard parts.

Unique Advantages

• Smaller-sized audio-grade option: The LKS series offers a smaller footprint compared with certain standard grades while the datasheet identifies an audible tone-quality improvement when used as a replacement.
• Secure snap-in mounting: Radial snap-in terminals provide a mechanically robust connection to PCBs for vertical can mounting.
• Defined ripple handling: 3 A ripple current at 120 Hz supports filtering and smoothing duties in low-frequency power domains.
• Wide operating temperature range: Rated from −40°C to +85°C, suitable for many electronic environments within that range.
• Measured endurance and reliability: Endurance specified at 1000 hours at 85°C with clear acceptance criteria for capacitance, tan δ, and leakage current after testing.
• Regulatory compliance: RoHS conformity helps meet environmental requirements for commercial and consumer products.
