LKS1V103MESZ

The LKS1V103MESZ is a Nichicon LKS series snap-in terminal aluminum electrolytic capacitor tailored for audio equipment and general-purpose electronic applications. This smaller-sized, polarized snap-in can be used as an upgrade from small standard products to help achieve an audible improvement in tone quality.

Key electrical attributes include a 10 mF capacitance at 35 V, a rated operating temperature range of −40°C to +85°C, and RoHS compliance (2011/65/EU, (EU)2015/863).

Key Features

• Electrolytic Core: Aluminum electrolytic construction providing 10 mF capacitance suitable for bulk energy storage and filtering in polarized circuits.
• Rated Voltage & Tolerance: 35 V rated voltage with a capacitance tolerance of ±20% (measured at 120 Hz, 20°C).
• Snap-in Mounting & Package: Snap-in terminal type in a radial can snap-in package for secure vertical board mounting and robust mechanical retention.
• Thermal and Endurance Ratings: Operates across −40°C to +85°C with an endurance specification of 1000 hours at 85°C under rated voltage.
• Ripple Current Capability: Rated low-frequency ripple current of 2.95 A at 120 Hz, suitable for applications with moderate AC ripple stress.
• Leakage Current Specification: Leakage current after 5 minutes at 20°C does not exceed 3√CV (μA) as specified in the LKS series datasheet.
• RoHS Compliance: Conforms to RoHS directive (2011/65/EU, (EU)2015/863), supporting regulatory requirements for restricted substances.
• Compact Dimensions: Package size listed as L: 5 × D: 2.2 cm, offering a smaller form factor within the LKS series.

Typical Applications

• Audio Equipment — Used as a snap-in polarized capacitor to replace small standard parts, helping to improve perceived tone quality in audio power and signal circuits.
• General-Purpose Electronics — Bulk energy storage and smoothing in general-purpose circuits where a compact snap-in electrolytic is required.
• Board-Level Power Modules — Provides ripple handling and decoupling at 35 V systems within the LKS series operating temperature and endurance limits.

Unique Advantages

• Designed for audio upgrades: Specifically noted for delivering a tone-quality improvement when used to replace smaller standard components in audio equipment.
• Robust ripple performance: 2.95 A ripple current rating at 120 Hz supports applications with moderate AC ripple requirements.
