TDK Corporation (TSE: 6762) has extended its portfolio of EPCOS ERU SMT power inductors with the ERU16 choke series, comprised of ten different types. The inductance values of the new B82559B*A016 series, which replaces the former B82559A*A016 series, extend from 1.0 µH to 30 µH, and their saturation currents range from 10.3 A DC to 40.4 A DC at 25 °C.
NFC is an abbreviation of Near Field Communication; it is a type of short-range wireless communications. NFC is a function that can perform data communications and authentication when two NFC-compatible devices are brought close together, and adoption in smart phones has been growing rapidly in recent years. Increased use in peripheral devices including wearable terminals, such as smart watches, has also been observed. NFC is used in many situations including cashless payment and authentication of connections with peripheral devices, and it is expected to be used for even more diverse applications as we move towards a touchless society. This article introduces the main components used in NFC circuits: NFC antenna, magnetic sheet, LC filter inductor, single-end circuit balun, and electric double-layer capacitor (EDLC/supercapacitor).
The number of smartphones and other mobile devices that are compatible with NFC (Near Field Communication) is increasing. Thanks to the adoption of a newly-developed low-loss ferrite material, TDK’s MLJ series multilayer ferrite coils now offer improved communication properties which are ideal for NFC-equipped devices, while featuring compact package sizes.
TDK Corporation has extended its range of dual inductors to include the new EPCOS series B82477D6*. The seven series types cover an inductance range from 2 x 3.9 µH to 2 x 47 µH and are designed for maximum rated currents from 2.83 A to 7.05 A. A special feature of the inductors, which are certified according to AEC-Q200 and compatible with RoHS, are the high saturation currents of up to 16.1 A. The magnetically shielded inductors have dimensions of just 12.5 x 12.5 x 10.5 mm3 and are designed for a wide temperature range of -55°C to +150 °C. Depending on the type, the inductors offer very high coupling factors of the two windings from 97 to 99 per cent.
As the electrification of automobiles advances, power consumption control is becoming an increasingly important factor. LED Lighting Technology design reduces power consumption, increases lifecycle, offers design freedom and overall control. It is now used in Automotive functions including headlights and interior lighting. The TDK Group offers an extensive lineup of power inductors for use in LED drivers optimized for different systems including step-up, step-down, and step-up/step-down types.
Automakers are incorporating more multifunctional capabilities into automobiles as they seek to make autonomous driving a reality. Electronic control units (ECUs) for advanced driver assistance systems are consuming more power, and the latest trend is toward ECU integration—installing an ECU close to the engine room or other working part. For these reasons, the number of electronic devices and components built into cars these days is on the rise, and the reliability of the electronic components used in the electronics is having a growing impact on the reliability of the vehicle overall.
The evolution of sensing technology and communication network contribute to the realization of Autonomous driving society and its growth. In association with full-scale expansion of the "5G service" next-generation wireless communication standard, great attention is being placed on wireless technology intended for "vehicle-to-vehicle and infrastructure-to-vehicle communication" (V2X) to communicate data between automobiles and their surroundings. While the TDK Group can offer a lineup of various electronic components for V2X, this article introduces a selection of IMU (Inertial Measurement Unit) and high-frequency products for Telematics Control Units (TCUs).
With the increasing speed and sophistication of interfaces in cars, the PoC (Power over Coax) approach is gaining in popularity, as it allows superimposing signals and power in one coaxial cable, for example for LVDS based automotive camera systems. A PoC filter consisting of one or more inductors and chip beads is used on the circuit side to separate the signal and the power supply current. This is important in terms of maintaining communication quality. The PoC filter therefore requires inductors that realize high impedance for AC components over a wide bandwidth range from low to high frequencies.
The demand for high-speed automotive onboard interfaces is increasing, with a view towards supporting driving safety, reducing the environmental load, and improving comfort. For bidirectional communication, the automotive Ethernet format is commonly used, while LVDS is the choice for one-way communication. With LVDS (Low Voltage Differential Signaling), the preferred approach is to also adopt the PoC (Power over Coax) method that enables transmission of the signal and power supply over a single coaxial cable, thereby reducing the weight of wire harnesses in the car. This page describes usage examples and effects of inductors and chip beads specifically recommended for PoC filter applications.
We are transitioning from an age where people drive cars to an age where people provide mobility services and utilize autonomous driving capability. As a consequence, the number of electronic parts used in cars is steadily rising. If even a single component fails, a specific function may be impaired, which as a result, severe performance requirements are placed on the components reliability. TDK provides high frequency power inductors for automotive applications that are designed for outstanding reliability to reduce failure risks – HPL series, TFM series, and BCL series.
