LKS1E103MESY

The LKS1E103MESY is a snap‑in aluminum electrolytic capacitor from Nichicon's LKS series, offering 10,000 µF capacitance at a 25 V rating in a compact 20 × 45 mm can. Designed for smaller‑sized audio and general‑purpose applications, it delivers bulk energy storage with specifications suited to assemblies that require snap‑in mounting and tray packing for production handling.

Key electrical characteristics include a low‑frequency ripple current rating of 2.45 A (120 Hz), a tangent of loss angle (tan δ) of 0.30 at 20 °C/120 Hz, and an operating temperature range from −40 °C to +85 °C with 1,000 hours endurance at 85 °C.

Key Features

• High bulk capacitance: 10,000 µF nominal capacitance with a tolerance of −20% to +20%, providing substantial energy storage for smoothing and decoupling in general‑purpose circuits.
• Rated voltage: 25 V working voltage suitable for many low‑voltage power rails and audio circuits.
• Snap‑in mounting: Snap‑in terminal type and radial can (snap‑in package case) for secure mechanical mounting in panel or bulk assembly environments.
• Ripple current capability: Low‑frequency ripple current rated at 2.45 A (120 Hz), enabling handling of AC ripple in power circuits at the specified measurement condition.
• Loss characteristics: tan δ = 0.30 measured at 20 °C, 120 Hz, providing a quantifiable dissipation factor for design verification.
• Wide operating temperature and endurance: −40 °C to +85 °C operating range with 1,000 hours rated life at 85 °C per endurance specification.
• Leakage current specification: Specified leakage current of 1,500 µA at rated conditions.
• Packaging and compliance: Supplied in tray packing and compliant with RoHS requirements.

Typical Applications

• Audio equipment: Suited for audio applications where the LKS series' smaller size and tone‑quality focus are required, delivering bulk capacitance in compact enclosures.
• General‑purpose electronics: Used where high capacitance and snap‑in mounting are beneficial for energy storage and bulk filtering in general‑purpose circuits.
• Production assembly: Tray packing supports automated or manual assembly processes for PCB or chassis installations requiring snap‑in components.

Unique Advantages

• Substantial capacitance in a compact can: 10,000 µF in a 20 × 45 mm package enables designers to save board area while maintaining required bulk storage.
• Designable ripple handling: Rated ripple current of 2.45 A at 120 Hz provides a measurable parameter for thermal and ripple budgeting in power design.
• Measured loss factor: tan δ = 0.30 at standard test conditions gives clear data for estimating dissipation and performance under AC excitation.
• Robust operating window: −40 °C to +85 °C range and 1,000 hours endurance at 85 °C support reliable operation across common ambient conditions and long‑term thermal stress.
• Assembly‑friendly format: Snap‑in terminals and tray packing facilitate repeatable mounting and handling in production environments.
• Regulatory compliance: RoHS‑compliant construction supports use in lead‑restricted assemblies.
