Nouvelle gamme de selfs mode commun, TCM

Exxelia introduit une nouvelle gamme  de selfs de mode commun, la gamme TCM. Fabriquée et qualifiée pour répondre aux exigences des applications aérospatiales, la gamme TCM est une solution compétitive dédiée aux les environnements sévères.


This extensive and cost-effective range is designed to be compatible with avionics applications.

The TCM series is available in a through-hole package for horizontal and vertical mounting. TCM common-mode chokes are offered with inductances from 0.7 to 47mH under rated currents from 0.3A to 4A, and thoroughly tested by a dielectric withstanding strength at 1500VAC. Their excellent thermal properties allow the TCMs to operate without a hitch from -55°C up to +125°C, which, combined to the high mechanical resistance of the chosen materials (all meeting to UL94 V0 rating) make those products the perfect fit for aviation, defense and transportation industries.

TCM series can be designed into circuit boards of a large number of power electronic devices used for a wide range of applications, including switch mode power supplies and converters, inverters, battery management systems, chargers.
Exxelia TCM series fully complies with the requirements of RoHS and REACH.

Exxelia Ohmcraft Custom Resistors Enable Metabolic Analyses of Live Cell Cultures in Pharmaceutical Research

To do so, they must rely on life science research and diagnostic instruments with complex high gain amplifier circuits. Leading manufacturers of this type of equipment have partnered with Exxelia Ohmcraft to design custom, high-resistance surface mount resistors that are essential to the function of these circuits. Specifically, oxygen consumption rate (OCR) and extracellular acidification rate (ECAR) are two key indicators of mitochondrial respiration and glycolysis that provide a systems-level view of cellular metabolic function in cultured cells. The analyzer equipment conducts these measurements automatically. “The accuracy and reliability of these tools are crucial to the researchers’ ability to make progress in their studies, which have the potential to change—and save—lives,” said Eric Van Wormer, Vice President of Exxelia Ohmcraft. “To meet the design needs of this particular application, we developed a custom resistor solution with a unique form factor and used special terminations to facilitate the manufacturability of the end product.” Exxelia Ohmcraft’s technology utilizes the proprietary Micropen electronic printing system to “print” precise, narrow, serpentine lines with resistive ink on a ceramic substrate, producing higher performance resistors over a wider range of values on a smaller surface area than is possible with conventional film resistor technology.
