Coilcraft Introduces XEL50xx Ultra Low-loss Power Inductors for High-frequency Applications

May 7, 2018 by TechWire International

New XEL50xx Family of high-performance, molded power inductors offer exceptionally low DC resistance and ultra-low AC losses, greatly improving power converter efficiency at high frequencies (2 to 5+ MHz) and high ripple current

The use of high switching frequencies or high ripple current allows a corresponding lower inductance value, which results in a physically smaller part for the same electrical specs. XEL50xx Family inductors measure just 5.28 x 5.48 mm with a maximum height of 3.2 mm. The XEL50xx Family is currently available in two models, the XEL5020 and XEL5030. A third model, the XEL5050 is expected late Q2 2018. The XEL5020 is available in six inductance values from 0.10 to 1.0 µH, with current ratings up to 39 Amps. The XEL5030 has 10 values from 0.13 to 4.7 µH and current ratings up to 44 Amps. All models offer soft saturation characteristics to withstand high current spikes and have no thermal aging issues.

Coilcraft’s New 0402-sized Ceramic Chip Inductors Provide Q Factors up to 162 at 2.4 GHz

January 23, 2018 by TechWire International

New 0402DC Series ceramic wirewound chip inductors offer the industry’s highest Q factors in an 0402 (1005) size – up to 162 at 2.4 GHz – for super low loss in high frequency circuits.

It is offered in 26 standard inductance values ranging from 3.0 to 120 nH. An additional 73 values are available upon request, including 0.1 nH increments from 2.8 nH to 10 nH. Most values are available with 2% tolerance. The 0402DC Series features a wirewound construction for extremely high self resonance – up to 16 GHz. It also offers DCR as low as 37 mΩ, significantly lower than other 0402-sized chip inductors. 0402DC Series chip inductors are ideal for impedance matching circuits for low band (700 – 960MHz) and high band (1710 – 2700MHz) antennas. Its 0402-sized package is perfect for smartphones and tablets. 0402DC Series inductors feature RoHS compliant, matte tin over nickel over silver-platinum-glass frit terminations and offer a maximum reflow temperature of 260°C. http://bit.ly/2n1Rvqy

New Ceramic Chip Inductors Provide the Industry’s Highest Q in an 0805 Package

September 5, 2017 by TechWire International

Coilcraft’s new 0805HP Series ceramic wirewound chip inductors offer the industry’s highest Q factors in an 0805 size at frequencies up to 3 GHz.

The 0805HP Series features a wirewound construction for highest possible self resonance – up to 9.5 GHz. It also offers significantly lower DCR (as low as 15 mΩ) than the previous generation products, making it appropriate for high current applications. It is available with 23 inductance values ranging from 2.6 to 820 nH, with 2% tolerance available for most values. http://bit.ly/2x7uuJk

New Coilcraft Automotive-grade Power Inductors Offer Superior Performance in a Compact Package

May 9, 2017 by TechWire International

Coilcraft’s new SRT8045 Series of magnetically shielded power inductors offer superior performance and a smaller package than previous-generation products. Measuring just 8.0 x 8.4 x 4.5 mm, the highly cost-effective SRT8045 has saturation current ratings up to 17.4 Amps and DC resistance as low as 7.7 mΩ, allowing users to dramatically reduce inductor size while maintaining excellent performance. http://bit.ly/2psooem #techwireintl
