We are excited to announce the release of the SMC/SPA series capacitors, a cutting-edge innovation designed to address the growing demand for efficient, reliable, and robust components in power electronics. These capacitors are purpose-built for a wide range of high-performance applications, particularly in systems requiring advanced power management, over-voltage protection, and efficient energy conversion. Whether used in industrial environments or specialized equipment, the SMC/SPA series capacitors deliver unparalleled performance and durability.

Key Features that Set SMC/SPA Series Capacitors Apart:

1.Self-Healing Technology for Enhanced Reliability

The SMC/SPA series employs advanced self-healing technology that ensures continuous operation even after dielectric breakdowns. This feature significantly enhances the lifespan and reliability of the capacitors, making them ideal for high-stress environments where uninterrupted performance is critical.

2.Wide Capacitance Range (1.0 to 50μF) and Voltage Support (300 to 6000Vac)

Designed to meet the diverse needs of power electronics, the SMC/SPA series offers a wide range of capacitance and voltage ratings. This flexibility allows for precise matching with system requirements, ensuring optimal performance in various applications.

3.High Over-Voltage and Over-Current Tolerance

Engineered to withstand high over-voltage and over-current conditions, these capacitors provide robust protection against electrical surges. This makes them indispensable in high-power systems that demand resilience in the face of fluctuating electrical loads, such as industrial drives, traction systems, and renewable energy converters.

4.Environmentally Friendly Dry-Type Design

The capacitors feature a dry-type construction, eliminating the need for harmful liquids or oils, and making them an eco-friendly choice for environmentally conscious industries. Their self-healing polypropylene film structure is housed in a durable aluminum or plastic casing, offering both physical protection and environmental sustainability.

5.Versatile Installation Options

The SMC/SPA series is designed for both horizontal and vertical installations, providing flexibility during assembly and integration into a variety of system architectures. This versatility makes it easier for engineers to adapt the capacitors to space-constrained or uniquely configured setups without compromising performance.

6.UL94-V0 Fire Resistance and Long Operational Life

Safety and longevity are critical in power electronics, and the SMC/SPA series delivers on both fronts. With a fire resistance rating of UL94-V0 and an operational life expectancy of 100,000 hours (at ΘHOTSPOT ≤ 55°C), these capacitors ensure long-term reliability and reduced maintenance needs, even in harsh operating conditions.

Unmatched Applications for Maximum Performance:

The SMC/SPA series capacitors are designed to excel in a wide array of demanding applications, ensuring both system stability and efficiency:

•Snubbers for SCRs and GTOs:

In power electronics, thyristors such as Silicon-Controlled Rectifiers (SCRs) and Gate Turn-Off Thyristors (GTOs) play a crucial role in controlling high power levels. SMC/SPA capacitors effectively minimize voltage spikes and surges, protecting these sensitive components and extending their lifespan.

•SCR Commutation:

The rapid switching of SCRs generates transients and noise, which can affect the stability of the system. The SMC/SPA capacitors’ ability to absorb and dampen these disturbances makes them an essential part of SCR commutation circuits, ensuring smooth and reliable operation.

•Harmonic Filters:

Harmonics generated by non-linear loads can degrade system performance and efficiency. The SMC/SPA series capacitors help filter out these unwanted harmonics, reducing power losses and improving overall system efficiency.

•Static Var Generators (SVG) and Static Var Compensators (SVC):

In reactive power compensation systems like SVGs and SVCs, the SMC/SPA capacitors provide critical energy storage and voltage stabilization. This improves power factor correction and maintains voltage levels, enhancing the efficiency of electrical grids and industrial power systems.

The SMC/SPA series capacitors are poised to set a new standard in the power electronics industry, combining performance, reliability, and sustainability in a single, robust package. Choose CABO for your next project and experience the difference that high-quality capacitors can make.
