What do molded power inductors bring to high efficiency, compact designs?
Modern hardware applications trend towards compact designs that are power efficient. Passive devices don’t get as much attention as a microcontroller’s many sleep and shutdown states. However, every drop of available efficiency adds up and can make a difference. It’s possible to improve power efficiency with the right inductor. Power inductors are a necessary component […]
Varistors ARE viable for surge protection
by Patrik Kalbermatten, KEMET Protecting sensitive electronic equipment against transient voltages in the form of surges that may be either circuit emanating from relays or motors, or significant ESD events such as lightning strikes, is a vital part of equipment design. Several technologies exist to protect sensitive electronic circuitry from voltage surges, including gas discharge […]
Choosing a capacitor? Ripple current capability matters as much as Farads
by Derick Stephens, KEMET Corporation Selecting capacitors for decoupling and filtering in power circuits may seem like a basic chore for electronics designers. Getting it right, however, can critically influence reliability and longevity, but is complicated by the fact that parameters tend to change with factors such as the temperature and operating frequency. Proper attention should […]
Going solderless – Press-Fit capacitors bring multiple benefits to circuit assembly
Solderless assembly of electronic components can deliver significant benefits in terms of simplicity, repeatability and some key electrical and mechanical considerations. However, to be acceptable, technologies such as Press-Fit need to satisfy stringent operational and performance requirements stipulated for the specific application and by standards bodies such as IEC. MARYANN FULTON, KEMET The need for […]
