  TDK Corporation presents the EPCOS LeaXield™ active filter module – a completely new solution for the minimization of earth leakage currents in power drive systems with frequency converters. Leakage current can cause RCDs (residual current device) to trip. In some applications this means that RCDs with low thresholds such as 30 mA cannot be [...]

  Dynamic DC Bias Model for accurate circuit simulation First tool for the dynamic simulation of DC bias characteristics of MLCCs More accurate power supply circuit simulation when used together with TDK technical support tools for inductors More efficient electronic circuit design TDK Corporation has expanded its technical support tools for MLCCs: The new DC [...]

    Miniaturization leap by 80 percent; extremely low insertion height of 0.1 mm 50 times higher absorption capability for ESD pulses Attractive alternative to TVS diodes     TDK Corporation presents a new series of EPCOS multilayer varistors of the CeraDiode® family, which includes the most compact, flattest and most rugged varistor for the ESD [...]

              TDK Corporation presents the completely revised 2013 edition of the EPCOS Data Book Ferrites and Accessories. Among the product highlights are innovative power materials for a wide range of temperatures, which enable the design of energy-efficient power supplies. For example, the power loss minimum of material N88 is [...]

              TDK Corporation presents a new series of EPCOS EMC filters. The B84142A*166 series of 2-line filters features types designed for rated currents of 10 A, 16 A, and 30 A at a rated voltage of 250 V AC (50/60 Hz). A particular feature is their very compact size: The [...]

              TDK Corporation has extended its MMZ portfolio of Gigaspira beads with the MMZ1005-V series, which features the world’s highest* impedance peak frequency in the 2.5 GHz range. The new EMC components enable, for the first time, simple and effective noise suppression of high-frequency signals above 2 GHz, as [...]

  TDK Corporation presents a new series of EPCOS SMT power inductors whose current capability is 10 percent higher than existing types. The components of the improved and highly reliable B82476B1*M100 series of SMT power inductors are designed for rated currents between 0.33 A and 7.5 A. The spectrum of inductance values ranges from 1.0 [...]

  TDK Corporation has expanded its TPL series of transponder coils with a new miniature version that is especially designed for use as an antenna coil in tire pressure monitoring systems (TPMS) for vehicles. Measuring in at just 7.85 mm x 2.70 mm x 2.70 mm the new TDK TPL802727 transponder coil offers the same [...]

  TDK Corporation presents two new series of narrowly toleranced EPCOS NTC thermistors in EIA 0402 and 0603 SMD case sizes. The components feature a rated resistance of 10 kΩ in tolerance classes ±1%, ±3% and ±5%. These narrow tolerances were made possible thanks to a new production technology and a rugged glass passivation, which [...]

  TDK Corporation presents two new series of EPCOS aluminum electrolytic capacitors in extremely compact snap-in designs. The dimensions of the new B43640* and B43644* series are 22 x 25 mm to 35 x 55 mm (diameter x height), depending on the type. Thus, both series are significantly more compact than previous series for identical [...]
