TDK Corporation (TSE:6762) has extended its range of coupled inductors to include the new EPCOS series B82472D6*. The nine series types cover an inductance range of 2 x 2.2 µH to 2 x 47 µH and are designed for maximum rated currents of 1.1 A to 4.3 A. The RoHS-compliant chokes are certified in line with AEC-Q200 and feature high saturation currents of up to 7.95 A. The magnetically shielded inductors have dimensions of just 7.3 x 7.3 x 4.8 mm and are designed for a wide temperature range of between -55 °C and +150 °C. Depending on the type, the chokes offer very high coupling factors of the two windings, from 97 to 99 percent.

TDK Corporation has extended its portfolio of EPCOS ERU SMT power inductors with the ERU16 choke series, comprised of ten different types.

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.

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.

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).

As electronic devices become more advanced, the power supply voltage of LSIs used in them is lowered, so their power consumption can be reduced and their speed increased. However, a decrease in the power supply voltage also causes the requirements regarding voltage fluctuations to become more severe, creating a need for high-performance DC-DC converters to fulfill these characteristic requirements, and power inductors are important components that greatly affect their performance. TDK has a widely varied lineup of power inductor products, and this article describes and explains effective methods for using power inductors, and key points for selecting them, according to the required characteristics of DC-DC converters.

The SPM series power inductors are the metal composite type wire-wound inductors that have the coils integrally molded with metallic magnetic powder. Compared to ferrite-base wire-wound inductors, the SPM series inductors realize larger current, lower Rdc, smaller size and superior DC bias characteristic. In addition, they ensure low magnetic flux leakage and are effective as a means to suppress acoustic noise of the coil. This article introduces the structure, features, and application of these products, and other information that helps you in an easy-to-understand way.

The VLS series power inductors are magnetic shield (resin) type wound inductors that have been developed taking full advantage of the material technology and manufacturing processes that TDK have accumulated so far. This type of inductors can largely be classified into three categories: VLS-HBX/HBU series, VLS-CX series, and VLS-EX/AF/EX-H series; and they show respective excellent features. This article introduces the structure, features, and application purposes of these products, and other information that helps you in an easy-to-understand way.

This article introduces some causes of and effective measures against acoustic noise in power inductors, which are main components in power circuits of devices such as DC-DC converters.

Leakage fluxes in the VLS-EX series, CLF-NI series, and SPM series, which are representative power inductors offered by TDK, are visualized in 3D graphics. There is also helpful information in measures for leakage fluxes.
