Product Description

Overview of CM-Series Electrolytic Capacitors

The CM-Series compact long-life electrolytic capacitor is specifically engineered for industrial sewing machine applications. It features smaller case sizes compared to the SC series and a low profile of 5.5mm, making it ideal for space-constrained electronic assemblies. This surface mount device supports high-density PCB layouts and is compatible with automatic insertion machines using carrier tape, which helps streamline commercial production processes for enterprise customers.

Key Features of CM-Series Electrolytic Capacitors

Compact Low-Profile Design

The CM-Series offers reduced physical dimensions compared to the SC series, with a maximum height of 5.5mm. This compact form factor allows for more efficient use of PCB space, which is critical for modern miniaturized electronic devices in industrial applications. Three case diameter options (4mm, 5mm and 6.3mm) are available to accommodate different capacitance and voltage requirements.

High-Density PCB and Automation Compatibility

Designed for surface mounting, these capacitors are optimized for high-density PC board layouts. They are supplied on carrier tape, enabling seamless integration with automatic insertion equipment. This compatibility reduces manual labor requirements and improves production efficiency for commercial users engaged in large-scale manufacturing.

Long-Term Reliability

The capacitors undergo rigorous reliability testing to ensure consistent performance in industrial environments. They are rated for a load life of 2000 hours at 85℃ under rated voltage application, maintaining stable electrical characteristics throughout their service life. They also exhibit good resistance to soldering heat and low-temperature performance.
