TDK Co., Ltd. introduces the new B82559A * A033 series shielded EPCOS ERU33 high current choke. The new series of components are installed through holes and have an ultra-high saturation current of 32 A to 83 A at 100 ° C. There are six models available, covering 3.2 μ H to 10 μ The range of inductance values for H, with a DC resistance as low as 0.85 m Ω or 1.2 m Ω, depends on the model. The choke coil uses a flat wire winding and is very compact in size, only 33 x 33 x 15 mm. By thermally connecting the flat wire winding and the magnetic core, a large area of ferrite surface can be coupled and connected to the heat sink, greatly improving the heat dissipation performance.

Italy France Semiconductor released nine radio frequency integrated passive devices (RF IPDs) optimized for STM32WL wireless microcontroller (MCU). The new product is a monolithic integrated antenna impedance matching, balun and harmonic filter circuit.

Mao Ze Electronics will prepare the HotSwitch of Semtech Corporation from now on ® Protect IC. HotSwitch platform includes integrated load switch and electric fuse, with excellent advanced protection function set, which can protect the electronic system from the impact of typical circuit transient and steady-state fault conditions.

A few days ago, Vishay Intertechnology, Inc. announced the launch of three new series of automotive surface-mount standard rectifiers - 2 A SE20Nx, 3 A SE30Nx and 4 A SE40Nx, all of which are the industry’s advanced thin, wettable side DFN3820A packaging devices. The reverse voltages of SE20Nx, SE30Nx and SE40Nx are 200 V, 400 V and 600 V respectively, which can provide space-saving and efficient solutions for commercial, industrial and automotive applications of power line polarity protection and rail-to-rail protection.
