Calculating the Current Through a Bank of Capacitors

2019-10-17T18:31:20+00:00July 3rd, 2019|

Many times, different technologies of capacitors are needed to accomplish different tasks at the same point in a circuit. One of the most common combinations is Aluminum Electrolytic and Film capacitors. The Aluminum Electrolytic capacitors handle the bulk of the capacitance while the film capacitors help take some of the current from the Aluminum Electrolytics, all while filtering the higher frequencies that the Aluminum Electrolytics cannot.

Polymer Tantalum Capacitors Continue to Toughen Up to Meet Automotive Demands

2019-10-10T15:11:53+00:00June 4th, 2019|

New materials and manufacturing processes enable polymer tantalum capacitors to pass automotive AEC-Q200 stress test requirements, as well specific electrical transient tests. Although the market supply chain challenges with high CV MLCC‘s availability and new automotive requirements with electrification, digitalization, and autonomous driving are bringing new opportunities.

Ready to Flex?

2019-11-18T16:52:05+00:00April 23rd, 2019|

KEMET is the pioneer in noise suppression based on a unique flexible concept. It is a new material outstripping the limitations of ferrite, they suppress noise by applying magnetic loss. Composed of micro-magnetic foils suspended in a flexible polymer material, the Flex Suppressor attenuates or suppresses Electromagnetic and Radio Frequency Interferences (EMI/RFI).

Make Sense of the Proximity Sensor

2019-11-11T21:24:34+00:00April 1st, 2019|

There are so many more devices around us that use proximity sensor technology than you'd think. This technology is already being used in areas like automotive, industrial, home automation, and home appliances. The possibilities are endless! Learn all about how proximity sensors work, various applications, and how KEMET's line of sensors are paving the way for the future.

Designing for AC circuits requires thinking differently about MLCC choices

2019-12-06T14:09:46+00:00March 26th, 2019|

For some time MLCCs have been used in AC circuits primarily as safety devices, but what about non-safety applications? KEMET’s new 250 VAC rated MLCCs are ideal for non-safety critical applications such as: AC-DC converters, AC filtering, power factor correction, and power supply.

Pyro Switch: Hidden IR detection

2019-10-31T19:12:46+00:00March 11th, 2019|

Our Pyroelectric sensors are an interesting device that allows you to detect the presence of a person while hiding the sensor from view. This property works well when you want to enable an otherwise static poster into an animated one by using an LED and a microcontroller. For simplicity, we used an LED, a microcontroller Arduino, and our SS-430 IR Pyroelectric Sensor.
