Miniature AEC-Q200-certified power inductors have a low profile
TT Electronics, a global provider of engineered electronics for performance critical applications, has announced the introduction of the HA66 SMD power inductors for use in high power density applications where size is critical. The inductors’ compact design, together with their AEC-Q200 certification provide the performance and reliability levels that automotive and high reliability industrial applications demand. […]
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 […]
Low-profile power inductors designed for advanced driver assistance systems
TDK Corporation announces the MLD2012 series of multilayer low-profile power inductors for automotive circuits. The new components that are based on a ferrite core are available in a compact IEC 2012 (EIA 0805) package with a footprint of 2.0 mm x 1.25 mm and an insertion height of just 0.5 mm. The power inductors, which […]
High-current ceramic inductors, air coils now available as models in high-frequency simulation software
As part of their Microwave Global Models cooperation, Würth Elektronik eiSos and Modelithics are making two more Würth Elektronik eiSos product series available. This means that developers can simulate the high frequency response of WE-KI HC high current ceramic inductors and the WE-CAIR air coils in models. The models offer advanced functions to improve accuracy […]
Thin-film chip inductors target automotive signal and power applications
AVX Corporation has released a new series of thin film multilayer chip inductors especially designed to meet demanding performance specifications in automotive signal and power applications. Qualified to AEC-Q200, the new automotive-grade Accu-L Series inductors exhibit ultra-tight inductance tolerances down to ±0.05nH, in addition to: RF power capabilities, high Q, high self-resonant frequency (SRF), low DC resistance (Rdc), and […]
Magnetically shielded SMD power inductors for high inductances
Metal Hybrid Inductors, known as the CDMT40 series, offer more than double the inductance values of earlier introductions while maintaining the same small footprint. A newly developed composite material draws on the special qualities of two different metals in the mold structure to provide magnetic shielding, small size, and high current ratings. The CDMT40D40 also […]
Magnetically shielded, SMD coupled power choke sports low dc resistance
WE-DPC HV (Double Power Choke High Voltage) is a magnetically shielded, SMD coupled power choke with two identical windings and a high isolation voltage of 1.5 kV. It is the smallest product of its type in the Würth Elektronik eiSos portfolio. With this power choke in a 5030 package, customers can attain a 40 percent […]
Common-mode line filters for SMPS replace discontinued units
The PMCU Series of common mode line filters is designed for switching power supply applications. Offered in both standard winding (for higher efficiency) and sectional winding (for improved high-frequency performance), the updated PMCU offerings have been expanded to include a direct cross for over three dozen PLA10ANxxx and PLA10ASxxx EMIFIL series components recently discontinued by […]
