Single-phase EMI filters for AC and DC applications
TDK Corporation 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 […]
Choke sample kits designed for saturation currents from 32 A to 83 A at +100°C
TDK Corporation presents a sample kit for the B82559A*A033 series of shielded EPCOS ERU 33 high-current chokes. The sample kit (ordering number: B82559X033) contains two pieces of each of the six standard types of this series. In addition to the standard types in the sample kit, customized variants of the chokes with other inductance values […]
Power supply operates from 400/440/480 Vac Delta and Wye inputs
TDK Corporation announces the addition of the TDK-Lambda brand TPS4000-12 power supply, further extending the existing 3kW to 4kW rated TPS series. Delivering up to 2040W output power (12V at 170A) in a 2U high package, the TPS4000 series operates from a wide range Delta or Wye 350 – 528Vac three-phase input. These industrial power […]
Inrush current limiter is SMD saves board space, weight
TDK Corporation has developed the J404, the world’s first surface-mountable inrush current limiter (ICL) based on PTC (positive temperature coefficient) technology. Designed for DC voltages of up to 500 V and AC voltages of up to 350 V, the device (order number B59404J0170A062) automatically and intrinsically limits excessive currents in applications such as DC links […]
Tiny inductors save board space
TDK Corporation has announced the introduction of its new PLEA85 series of high-efficiency power inductors developed for battery-powered wearables and other devices, improving operating times. The new series has the lowest profile* in the industry, due to the use of TDK’s newly developed low-loss magnetic material and its thin-film processing techniques. Mass production of the […]
Coupled inductors improve power converter efficiency
TDK Corporation has expanded its family of flat wire inductors with the high-performance EPCOS ERUC23 coupled inductor series (B82559S*). In such components, two windings share a single magnetic core. The new series comprises six types covering a coupled inductance range from 1.4 µH to 4.1 µH and saturation currents from 50 A to 97 A. […]
Ceramic caps feature low electrical resistance
TDK Corporation has expanded its CN series of multilayer ceramic capacitors (MLCCs) with a unique design and structure. Unlike conventional soft termination MLCCs with the entire terminal electrodes covered with resin layers, the new design features resin layers covering only a board mounting side, allowing electric current to pass outside the layers and reducing electrical […]
Contactors switch high-voltage DC from lithium batteries
TDK Corporation presents HVC27 (B88269X*), its new generation of high-voltage contactors that can safely and reliably switch off continuous DC currents of 300 A to 500 A and operating DC voltages of up to 1000 V in lithium-ion batteries in 20 ms or less, depending on the type. This is made possible by the gas-filled […]
Thin-film capacitor commode mode filters offer noise control in high speed differential transmission
TDK Corporation has announced the introduction of its new TCM0403T series of noise reduction common mode filters for high-speed interface differential transmission (0.45 x 0.3 x 0.23 mm – L x W x H). Mass production of the product series began this month, June 2023. In recent years, as digital electronic equipment has become more […]
