  1. Filter Basics Series Part 2: Designing Basic Filter Circuits 3/18/2022

    In part two of this series, Knowles covers how RF designers can use the different frequency dependencies of capacitors and inductors to manipulate impedance and create various filter responses. 

  2. Surface-Mount Vs. Through-Hole Technology 3/14/2022

    There are two main mounting schemes for placing components on a printed circuit board (PCB): through-hole technology (THT) and surface-mount technology (SMT). Given its popularity over the last few decades, it’s no surprise that designers default to SMT, but there are advantages to both schemes that are worth exploring, especially for high-reliability application designs.

  3. Filter Basics Series Part 1: Resistance, Capacitance, Inductance, And Impedance 2/18/2022

    To kick off this series, Knowles Precision Devices breaks down the basic properties, impacting capacitor and inductor performance including resistance, capacitance, inductance, and impedance.

  4. SLCs Vs. MLCCs: Which Capacitor Type Is Right For My Application? 2/9/2022

    In general, SLCs are well-suited for high-frequency, low-voltage RF and microwave applications, while MLCCs can be used for all types of high-capacitance, high-voltage applications within a much more limited frequency range. 

  5. Bring Us Your Toughest Challenges 2/4/2022

    At Knowles Precision Devices, we purposely avoid commodity components. What we thrive on is doing the hard things. We handle the specialty components that go in systems that cannot fail and that operate at extremely high voltages, temperatures, or frequencies.

  6. Striking A Balance For Spectrum Needs: 5G Communications Vs. Aircraft Altimeter Operations 2/2/2022

    On Jan. 19, 2022, many international airlines canceled or delayed flights to major US airports where they believed 5G signals could possibly interfere with the radar signals required to properly operate landing equipment on their planes. Working through this potential interference issue is critical because 5G is not going anywhere.

  7. Further Increase MLCC Reliability With CSAM Testing 2/2/2022

    As a result of tacking many layers of dielectric and electrodes on top one another, there are a number of issues that can be introduced during the manufacturing process that are not problematic when working with SLCs.

  8. Expanding Filter Technology Offerings For Low-Frequency Applications 1/14/2022

    Knowles' acquisition of IMC has allowed an expansion of offerings to serve applications operating in the lower portion of the frequency range from the VHF to the L-band.

  9. Wrapping Up 2021 With Knowles Precision Devices' President Chris Dugan 12/8/2021

    Throughout the COVID-19 pandemic, Knowles Precision Devices has stayed focused on our primary goal of helping our customers address their most challenging application needs by providing high-performance components and innovative solutions. While 2021 did offer some unique challenges, overall, it was an exceptional year for our business.

  10. New Low Loss, Ultra Stable High-Capacitance MLCCs For Power Electronics 12/1/2021

    Knowles' newest line of multilayer ceramic capacitors (MLCCs) built with Hiteca™ delivers high capacitance stability over high temperature and voltage as well as lower parasitic losses under common operating conditions.
