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 […]
Wet electrolytic tantalum caps handle 230°C
AVX Corporation, a manufacturer and supplier of advanced electronic components and interconnect, sensor, control, and antenna solutions, has launched a new high-temperature wet electrolytic tantalum capacitor series. Designed for use at 230°C, the new TWA-X Series wet electrolytic tantalum capacitors feature a high-capacitance cathode system that achieves high CV performance in standard case sizes and a […]
Power film capacitors for high power, high frequency applications
KEMET announced two new series of power film capacitors that meet the requirements of AEC-Q200. The C4AQ series is suited for industrial, automotive and power supply designs for DC link, DC filtering and energy storage applications, while the C4AF series addresses similar applications, but is specifically designed for harsh environments. The new RoHS compliant capacitors […]
AC capacitors for filter applications range from 2 µF to 50 µF
TDK Corporation presents a new series of EPCOS MKP AC capacitors for filter applications. The components of the B33331V series are designed for a rated voltage of 460 VRMS, corresponding to a peak voltage of 650 V, and cover a capacitance range from 2 µF to 50 µF. Both the cans and the tops are constructed of aluminum, making […]
Polymer capacitors deliver stability and endurance in automotive applications
KEMET introduced its first 150°C automotive KO-CAP capacitor. The T599 KO-CAP high-humidity/high-temperature performance polymer series delivers stability and endurance under harsh humidity and temperature conditions. Building on the success of the T598 series, KEMET further refined the design, materials and manufacturing to ensure T599 delivers higher stability and endurance under harsh conditions. T599 capacitors pass 1,000 hours of […]
Film capacitors for DC links handle high temperature and humidity
TDK Corporation today announced that it has extended its range of EPCOS film capacitors for DC link applications. The B3277*H series now provides types for particularly harsh environmental conditions. The robustness has been verified in a temperature, humidity, bias (THB) test at 60 °C, 95 percent relative humidity, and the rated voltage for 1000 hours. […]
Better environmental specs for dc link capacitors
TDK Corporation (TSE:6762) has extended its range of EPCOS film capacitors for DC link applications. The B3277*H series now provides types for particularly harsh environmental conditions. The robustness has been verified in a temperature, humidity, bias (THB) test at 60 °C, 95 percent relative humidity, and the rated voltage for 1000 hours. Special types are also […]
Parasitic capacitance, inductance, and displacement current
When two electrical conductors are physically close, carry a charge, and there’s a voltage potential between them, they create a virtual capacitor between them, even if the conductors are insulated. The virtual capacitor between them is known as parasitic or stray capacitance. This can happen anywhere but is most troublesome between traces on printed circuit […]
