The basics of thermistors in thermal management
Thermistors can reliably switch in thermal protection to keep power electronics cool. SONJA BROWN | EPCOS, A TDK GROUP CO. All semiconductors generate thermal losses, of course. Thermal losses in power semiconductors can range from a few watts to multiple kilowatts. In heatsinks, the conductive capability is typically measured in °K/W. The smaller the conductive […]
EMI suppression capacitors rated for 350 V AC
TDK Corporation presents a new series of robust EPCOS MKP X2 capacitors for EMI suppression. Compared with conventional X2 capacitors designed for rated voltages of 305 V AC, these new components offer a higher rated voltage of 350 V AC. This makes them suitable for EMI suppression in input filters – specifically for applications on […]
Compact power chokes handle up to 37 A
TDK Corporation has extended its portfolio of EPCOS ERU SMT power inductors with the ERU16 choke series that comprises ten different types. The inductance values of the new B82559*A016 series extend from 1.0 µH to 30 µH and their saturation currents range from 9.2 A DC to 37 A DC. The outstanding feature of these […]
Advances in dc-link power capacitor technology
Compact and efficient dc-links have become practical thanks partly to ceramic capacitor designs that excel at thermal stability and feature low parasitic inductance. Matt Reynolds, EPCOS, a TDK Group Company The technology behind capacitors has been around since late 1745 when a German physicist found that an electrical charge could be stored by connecting a […]
Power inductors provide wide temperature range for automotive apps
TDK Corporation has further expanded its CLF-NI-D series of rugged power inductors with new types in three additional sizes: CLF5030NI-D with dimensions of 5.0 mm x 5.3 mm x 2.7 mm, CLF10060NI-D measuring 10.0 mm x 10.1 mm x 6.0 mm and CLF12577NI-D at 12.5 mm x 12.8 mm x 7.7 mm. The new power […]
Aluminum electrolytic capacitors use snap-in design
TDK Corporation announced compact versions within the B43640 and B43644 series of aluminum electrolytic capacitors with a snap-in design for rated voltages of 400 V and 450 V. In comparison with the previous versions they are up to 15 percent more compact. All types are suitable for a maximum operating temperature of 105 °C. All […]
450-Vac film caps house two capacitors in one aluminum enclosure
TDK Corporation presents two new series of robust EPCOS alternating current (AC) capacitors. Both the cans and the tops of the components are constructed of aluminum, making them particularly robust. All capacitors in the B33331* and B33335* series are CE-compliant, have both VDE approval in accordance with EN/IEC 60252-1 Class A and UL approval. Thanks […]
DC link capacitor for IGBT modules
TDK Corporation presents a new EPCOS DC link capacitor that has been specifically designed for the HybridPACK™ 1-DC6 IGBT module from Infineon Technologies. The outstanding features of this component are the six busbar terminals with dimensions that are matched precisely to fit the IGBT module. This multiple contacting produces an excellent current capability while at […]
