TDK Corporation presents its new B33331I6* series, compact EPCOS motor-run capacitors that comply with safety class S2 as well as the IEC 60335-2-24 standard, that will come onto the market in September 2023. The robust aluminum cans have extremely compact dimensions, making the series now the most compact motor-run capacitors on the market. Depending on the capacitance, the diameters are only 30 mm or 35 mm, and the heights vary between 73 mm and 103 mm including the connections. They are designed for a voltage of 450 V AC at 50/60 Hz, and, with 13 types, cover a capacitance range from 1 μF to 20 μF.

The self-healing resin-filled capacitors are equipped with an internal overpressure breakaway protection and are designed for a lifetime of 10,000 hours at 450 V AC. Standard connections are 2+2 fast-on connectors (6.3 mm x 0.8 mm) and can be modified to customer specifications. Versions with an M8 bolt at the bottom of the housing are also available. All types have approvals according to UL and VDE and carry the CE mark.

Typical applications of these motor run capacitors are compressor motors of refrigerators and freezers and

The necessary change to environmentally friendly use of energy leads to the high demand for high-voltage and high-current DC applications.
TDK offers the High-Voltage Contactors (HVC) series which meet the requirements for High-Voltage DC emergency disconnection applications up to 600 A in electric cars, trucks, busses and DC fast chargers.
HVC series features excellent extinguishing characteristics in combination with a bipolar design for charging and discharging.

TDK Corporation (TSE: 6762) presents ModCapTM HF, a modular capacitor concept for DC link applications that is able to work at very high switching frequencies. The six newly developed power capacitors of the B25647A* series are available for rated voltages from 900 V to 1600 V and cover a capacitance spectrum from 640 µF to 1850 µF. Depending on the type, the rated currents range from 160 A to 210 A with a maximum permitted hot spot temperature of 90 °C.

Thanks to the ultra-low ESL value of only 8 nH and to its flat ESR vs Freq evolution that allows minimizing losses even at high frequency, ModCap HF is particularly well suited for fast-switching SiC-based inverters. The very low self-inductance prevents voltage overshooting on the power semiconductors when the current is shut off. As a result, generally, no snubber capacitors are needed.

In recent years, optical transmission systems have been adopted at high rate because of the increase in capacity and speed of communication.
Among them, a semiconductor laser that is positioned as an important component requiring a temperature sensor to keep the ambient temperature constant. A thermocouple can be used as a temperature sensor, but the NTCWS series of NTC thermistor is more suited to this application.

The NTCWS series can be mounted by wire bonding, achieving small size, high accuracy and unquestionable reliability.

TDK Corporation (TSE:6762) presents the EPCOS B72307S0* (StandarD S07 Compact Series) and B72310S0* (StandarD S10 Compact Series) series of extremely compact, leaded disk varistors. The new varistors cover a wide voltage range from 115 VRMS to 460 VRMS in the StandarD S07 Compact series and from 130 VRMS to 680 VRMS in the StandarD S10 Compact series. The maximum surge current capability of a single pulse current (8/20 µs) is up to 1200 A for the StandarD S07 Compact types, and up to 2500 A for the StandarD S10 Compact types. They offer a multiple surge current capability of 500 A (StandarD S07 Compact) or 1500 A (StandarD S10 Compact), according to UL 1449, 4th edition, type 5 listed. The varistors can be operated up to an ambient temperature of 105 °C without derating.

TDK Corporation (TSE:6762) presents the new B78302A* series of compact EPCOS transformers with innovative E5 cores for ultrasonic applications. It comprises three types with transformation ratios between 1:1:10.8 and 1:1:15.3. Depending on the type, the new transformers in SMD design offer inductance values between 2 mH and 4 mH and are suitable for frequencies from 50 kHz to 300 kHz. The AEC-Q200 qualified components have very compact dimensions of only 8.1 x 7.0 x 7.0 mm and are shielded by a counter-winding for better interference suppression. The permissible temperature range is between -40 °C and +125 °C.

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.
