About Dielectric Laboratories


Dielectric Laboratories was bought by Dover Corporation, which in 2013 spun out to form Knowles Corporation, a stand-alone, publicly traded business. As a division of Knowles Corporation, Knowles Precision Devices (KPD) focuses on producing a wide range of highly engineered capacitors and microwave-to-millimeter wave components for use in crucial applications in the military, medical, electric car, and 5G business segments. As a result, it is possible to find their products in various devices, including pacemakers, MRI machines, satellites, airplanes, electric cars, and mobile phone base stations.


They produce specialty components; thus, as a manufacturer, they decide to take on the complex problems that come with high-reliability, high-temperature, high-performance, and high-frequency solutions. It is based on their dedication to innovation, seen in their continued efforts to manufacture high-performance multi-layer ceramic capacitors. It is also possible to see their commitment in the novel ceramic formulas they use to produce the best mmWave filters currently on the market in terms of performance to the footprint.

FAQ About Dielectric Laboratories

Q1: What is a capacitor used for?

A: A capacitor is a device that stores electrical energy and consists of two conductors isolated from one another and placed close to one another. A straightforward illustration of one such storage device is a parallel-plate capacitor.


Q2: What are the 2 most common uses of capacitors?

A: Energy storage, power conditioning, electronic noise filtering, distant sensing, and signal coupling and decoupling are some of the most typical uses for capacitors. Capacitors are employed in various industries because they serve an essential and adaptable function in multiple applications.


Q3: What is the basic principle of a capacitor?

A: When an earthed conductor is relocated close to a conductor, a capacitor’s capacitance is assumed to rise dramatically. As a result, a capacitor has two plates with equal and opposite charges, which are spaced apart.


Q4: Where to order Dielectric Laboratories capacitors online?

A: BD Electronics provides a variety of models of capacitors made by Dielectric Laboratories. You can find the components you seek by visiting the BD Electronics website and searching the product category area.
