Power-supply chokes handle 32 A to 83 A
TDK Corporation presents the B82559A*A033 series of new shielded EPCOS ERU33 high-current chokes for through-hole mounting. Designed for very high saturation currents from 32 A to 83 A at 100 °C, the six new types cover a range of inductance values from 3.2 µH to 10 µH. DC resistances are as low as 0.85 mΩ […]
Automotive-grade SMT bar core chokes handle 28 A
With the magnetically shielded bar core choke WE-CHSA Performance, Würth Elektronik expands its portfolio of qualified products for automotive applications. The SMT high-current inductor represents an extension to the proven WE-CHSA series and differs from it only by a newly developed core material. As a result, WE-CHSA P – “P” as in performance – achieves the […]
Common-mode chokes support high-voltage, dc power line applications
Bourns, Inc. announced its new automotive-grade, AEC-Q200 compliant SRF7035A Common Mode Choke Series designed to support high voltage and current in DC power line applications. There are five impedance ratings with voltages up to 80 VDC and current up to 5 A. This gives designers additional flexibility and also expands the use of compact common-mode filters […]
Full bridge LLC transformer/resonant choke combo targets EV inverter apps
PREMO releases the new 11kW 3DPower solution, a Full Bridge LLC Transformer 150 µH + Resonant Choke 25 µH merged in 1 single unit. This innovation provides up to 40-50% reduction in volume compared with current discrete industrial solutions for the same power management. Most of the Power Converters (resonant topologies) in the market have […]
Common-mode chokes rated for 600 Vac, 2.5 kVac isolation
ITG Electronics has launched a range of Rugged Design Common Mode Chokes: the C301306H Series and C301369H Series. Offering higher voltage ratings and more robust hipot Isolation between two windings, the new products address the increasing demand for industrial, under-the-hood inverter applications. Typical common mode chokes for power application are rated at 250 volts alternating […]
Comprehensive study covers global permanent magnet industry
Recognized magnetics industry experts, Walt Benecki, Steve Constantinides, Dr. John Ormerod and Dr. Stan Trout are pleased to announce the publication of their comprehensive study of the global permanent magnet industry. This report is the definitive reference guide, an exhaustive market study which quantitatively describes the major commercial and technical features of the global permanent […]
Common-mode chokes designed for noise suppression in high-speed interfaces
Murata has released two new automotive common mode choke coils intended for noise suppression in high-speed interfaces that use Serializer/Deserializer (SerDes) on Power Over Coax (PoC). In-vehicle cameras have become increasingly popular in the autonomous vehicle market. SerDes is typically used in image data transmission interfaces. This, in turn, has led to the deployment of […]
Common-mode chokes optimized for high-speed interface noise suppression
Murata has released two automotive common mode choke coils intended for noise suppression in high-speed interfaces that use Serializer/Deserializer (SerDes) on Power Over Coax (PoC). Since this application requires a higher current compared to conventional differential interfaces, the DLW21SH391XQ2 and DLW21PH201XQ2 were developed specifically to handle a range from 300mA to 500mA. With sensor nodes becoming more compact, […]
Chokes handle up to 3kA gigaHertz-range frequencies
SMP Sintermetalle Prometheus GmbH & Co KG (SMP) offers chokes for medical technology applications. These inductive components are used in Magnetic Resonance Imaging (MRI) or Computed Tomography (CT), for example. Designed as filter or mains chokes they are not only compact, low-loss, and energy-efficient but also exceptionally quiet in operation – essential qualities for demanding […]
