TDK Corporation (TSE:6762) presents the B40910 series of hybrid polymer capacitors which can handle up to 4.6 A (100 kHz, +125 °C). This is because at room temperature the surface mount components offer an extremely low ESR value of 17 mΩ and 22 mΩ, respectively. Furthermore, their ESR does not change as much with temperature as standard electrolytic capacitors with liquid electrolytes. The 10 x 10.2 mm or 10 x 12.5 mm (D x H) small components have a rated voltage of 63 V and cover a capacitance range from 82 µF to 120 µF.

In resonant circuits used for wireless chargers and DC-DC converters, film capacitors have traditionally been used. However, advancements in the capacity expansion and high voltage resistance of Multilayer Ceramic Capacitors (MLCCs) have made it possible to replace film capacitors with MLCCs in these applications. Switching from film capacitors to MLCCs offers benefits such as miniaturization and reduced losses.

TDK Corporation (TSE:6762) presents two new types of the EPCOS InsuGate series (B78541A). These compact SMT transformers with high working voltage are suitable for gate driver applications for IGBTs and MOSFETs in e-mobility (qualification according to AEC-Q200 as well as according to AQG vibration profile) and in industrial electronics. The components with a MnZn ferrite core are designed for operating frequencies of 100 kHz to 500 kHz and operating temperatures of -40 °C to +150 °C. Depending on the type, the transformation ratios of the windings are 1:1.08 (B78541A2467A003) or 1:1.07:0.6 (B78541A2492A003). With a low coupling capacitance of only 4 pF, the SMT transformers are also suitable for use with SiC or GaN semiconductors.

With the expansion of AI usage, the energy consumed by computers has been increasing explosively. TDK is developing a spin memristor, an analog memory element that electrically mimics the synapses in the human brain. Devices that utilize this technology, known as neuromorphic devices, are expected to be over 100 times more energy-efficient than conventional devices. This device technology can be manufactured using techniques similar to those currently used for MRAM*1 production. Leveraging its expertise in magnetic technology, developed through HDD heads and magnetic sensors, TDK aims to reduce the energy needed for AI and to discover new AI devices that can learn in real-time and adapt to their environment and users.

TDK Corporation (TSE:6762) presents a new series of EPCOS power capacitors for DC link applications designed for an operating temperature of up to +105 °C. The components with the ordering code B25695E can operate at rated DC voltages from 700 V to 1300 V (voltage derating necessary from +85 °C). The ESR ranges from 1.0 mΩ to 2.7 mΩ, resulting in a current capability of up to 110 A at +70 °C, depending on the model (current derating necessary at higher temperatures). However, the film capacitors can repetitively withstand current peaks of up to 15.8 kA. At the rated voltage and +75 °C, their service life is 120,000 h – up to 35% more than the standard version

Protective measures are essential for ESD (Electrostatic Discharge) to prevent malfunctions or failures in electronic devices. However because these components are mounted directly on the line, selecting inappropriate ESD protective components can affect the signal on the line even under normal conditions. Examples include high-speed communication lines with differential signals, such as those used in automotive communications' CAN (Controller Area Network) and Ethernet. These can exhibit significant impacts, not only deteriorating communication quality but also potentially affecting EMC (Electromagnetic Compatibility) performance in the worst cases.

TDK Corporation (TSE:6762) presents two new varistor series in SMD design. The types of both series are available for a wide range of operating voltages from 175 VRMS to 460 VRMS, corresponding to 225 VDC to 615 VDC. While the B72210M* series of surge devices, which are equivalent to S14 leaded disk varistors, offers a surge current capability of 6000 A, the B72214M* series types, which are equivalent to S20 leaded disk varistors, have a high surge current capability of 10,000 A. All types are designed for a high operating temperature of a maximum of +125 °C and extremely damp heat environment (85% relative humidity at +85 °C).

TDK Corporation (TSE:6762) has expanded its portfolio of single-phase EMC filters with the B84742A*R725 series. These components serve AC as well as DC applications up to 250 V and rated currents from 6 A to 30 A. This means they can be used for increasingly popular DC infrastructure in the industrial and building sectors. Available in five versions, the 97 x 60 x 34.5 mm (L x W x H) small single-phase filters, weighing no more than 310 g, can be snapped quickly and conveniently onto the TH35 DIN rail, also known as a top-hat rail. The conductors are fastened with M4 screws, and the screw connection is equipped with touch protection.

TDK Corporation (TSE:6762) presents a demo kit (ordering code: Z25000Z2910Z001Z21) for the mechanically decoupled ultrasonic sensor module USSM1.0 PLUS-FS (ordering code: B59110W2111W032). This component can be used for obstacle detection and distance measurement under difficult environmental conditions including full sunlight and translucent target objects in autonomous mobile robots (AMR) or autonomous guided vehicles (AGVs).
