Introducing Our KC-LINK Surface Mount Capacitor!


KC-LINK series Film capacitors from KEMET Corporation are surface mount capacitors that are designed for fast-switching wide bandgap semiconductors that operate at higher voltages, temperatures, and frequencies. They use KEMET's proprietary C0G/NPO base metal electrode (BME) dielectric system, which offers high stability, low loss, and low thermal resistance.

Features

The main features of KC-LINK series Film capacitors may be summarized as follows:

1. High capacitance density of up to 20 microfarads

2. High voltage rating up to 3,000 VDC

3. High ripple current handling capability

4. No capacitance change versus DC voltage

5. Negligible capacitance change versus temperature

6. Operating temperature ranges up to 150°C

7. Low effective series resistance (ESR) and effective series inductance (ESL)

8. High mechanical robustness and reliability

9. Automotive grade available

Applications

  • DC-Link, snubber, and resonator for wide bandgap (WBG) semiconductors

  • Power converters and inverters for renewable energy, electric vehicles, and industrial equipment

  • High frequency and high power density circuits

  • Pulse power and energy storage systems

Frequently Asked Questions

What are the main features and benefits of KC-LINK series Film capacitors?

KC-LINK series Film capacitors have several features and benefits that make them suitable for demanding power applications, such as: - Low effective series resistance (ESR) and effective series inductance (ESL), which enable high ripple current handling and low power losses. - High temperature stability, with an operating temperature range up to 150°C and no change in capacitance versus DC voltage or temperature. - High mechanical robustness, with a base metal electrode (BME) dielectric system that allows the capacitor to be mounted without lead frames or metal frames. - High voltage capability, with a voltage range from 500 VDC to 1700 VDC. - High capacitance density, with a capacitance range from 0.5 nF to 20 µF.

What is KONNEKT technology and how does it enhance KC-LINK series Film capacitors?

KONNEKT technology is a high-density packaging technology that allows multiple KC-LINK capacitors to be bonded together using a transient liquid phase sintering (TLPS) material, forming a single surface mountable component. KONNEKT technology enhances KC-LINK series Film capacitors by: - Reducing ESR and ESL further, which increases ripple current handling and operating frequency range. - Enabling a low-loss orientation, which lowers ESR and ESL even more by aligning the electrodes parallel to the board. - Increasing capacitance and voltage options, by combining multiple capacitors in parallel or series configurations.

What are the typical applications for KC-LINK series Film capacitors?

KC-LINK series Film capacitors are suitable for various applications that require high efficiency and high density power conversion, such as: - DC-Link, snubber, and resonator applications for wide bandgap (WBG) semiconductors such as silicon carbide (SiC) and gallium nitride (GaN). - Power converters and inverters for renewable energy sources such as solar, wind, and hydro. - Electric vehicle (EV) charging stations and battery management systems (BMS). - Industrial drives and motor control systems. - Power supplies and adapters for consumer electronics.
