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.

Service robots play an increasingly vital role in society, from transportation and warehouse logistics to home entertainment and security. Regardless of their application, they need to sense changes in their surroundings in real-time to ensure safety while providing a positive user experience. To illustrate how various sensor technologies from TDK’s SmartSensor family can be applied in service robots, this article focuses on a robotic vacuum cleaner (RVC).
Early versions of robotic vacuums had very little intelligence, randomly bumping their way around the home and sometimes missing areas as they did not know where they had been. Often, they would unwittingly become trapped or run out of charge mid-sweep. And, as their dust box is comparatively small to a regular vacuum cleaner, if full, they could be sweeping but not collecting anything up. Over the years, with the innovative use of sensors and motor controllers, vacuum cleaning robots have become much smarter, overcoming these issues.

TDK Corporation (TSE:6762) presents the new EPCOS B72314S2* series (AdvanceD S14 Compact) of leaded disk varistors. The series covers a wide operating voltage ranging from 175 VRMS to 625 VRMS. The maximum surge current capability of a single pulse current (8/20 µs) is up to 6000 A. Furthermore, they offer a multiple surge current capability of 3000 A at 8/20 µs according to UL 1449, 4th edition, type 5 listed.

TDK's transparent conductive silver [Ag] alloy film (FleClear®) is a versatile material that has numerous use cases. Many of these uses require making direct electrical contact to the film's low resistance conductive surface in order to adequately perform the targeted applications. The following Application Note provides an overview of FleClear®, a step-by-step procedure of attaching an metal electrode, a list of needed equipment, along with the recommended materials to attach copper bus bars to the conductive surface. Additionally, where important, the suppliers and the respective numbers, are also listed..

Service robots are widely used in various situations such as logistics / transport, security, cleaning, housework, hobbies / entertainment and care / assistance. Since service robots are used in a wide variety of situations, it is necessary to fulfil many requirements such as smooth communication with humans (HMI), ensuring safety and responding to changes in the real time. In service robots, the role of a sensor is very important. In this article, we will take a vacuum cleaner robots as an example.

This is an electric double-layer capacitor with a metal foil laminate film (EDLC/supercapacitors).Low-resistance electric double-layer capacitors (EDLC/supercapacitors) are effective as capacitors for providing supplementary power during peak output, backup during power supply loss, energy harvesting, or regenerative energy storage. They are thin and lightweight, which makes them appealing for use in mobile products.

ThermoFuse® Varistors are used for overvoltage protection with an additional thermal element as safety feature.
Over the last years the fail safe functions got more popular and as a result the variety of thermally protect varistors increased on the market which resulted in many designs for different sizes and surge capabilities.
This article will show the benefits and features of TDK ThermoFuse® Varistor vs Standard Varistors.

TDK Corporation presents a new series of current-compensated EPCOS double-ring core chokes for the suppression of common-mode interferences.

TDK Corporation (TSE: 6762) presents the EPCOS E10 EM series, a new range of insulated SMT transformers that are suitable for various DC/DC converter topologies and gate driver circuits in e-mobility and industrial electronics. There are four models in the series, with basic winding insulation of a working voltage of 500 VRMS and reinforced insulation of 300 VRMS. The turns ratio is between 1:0.76 and 4:1, depending on the model.

TDK Corporation (TSE: 6762) presents a new range of highly accurate differential pressure sensors (part number B58621V*), designed as printed circuit boards. The sensors are designed for measurement ranges of 16 mbar full-scale (FS), 100 mbar FS and 7 bar FS, with absolute accuracy of up to ±1 percent FS at temperatures from -20 °C to +70 °C.
