Exxelia Ohmcraft Custom Resistors Help Ensure Speed and Accuracy of Automobile Electronics Testing
ROCHESTER, N.Y., July 28, 2020 — Before being sent off to dealerships for sale, automobiles are subject to a series of tests as part of the production process. To keep pace with industry trends and customer demands, today’s cars contain more electronic devices than ever, all of which must be tested ...
For this purpose, manufacturers of automotive testing systems have relied on Exxelia Ohmcraft—a leader in thick-film, high-voltage, high-precision resistor design and manufacturing—for more than 15 years.
This type of automotive testing ensures that all of the vehicle’s electronic components meet the most stringent testing standards, screening out any faulty devices or malfunctions. Tests are often run on multiple electronics simultaneously, increasing the complexity of these testing systems, which utilize precision low-noise chip resistors from Exxelia Ohmcraft for their accuracy and reliability.
“The automotive industry is rapidly changing and evolving, presenting manufacturers with not only new testing challenges, but the pressure to get their products into the market faster,” said Eric Van Wormer, Vice President of Exxelia Ohmcraft. “By leveraging Exxelia Ohmcraft’s custom surface mount resistors, automotive testing manufacturers are able to help their customers—automobile companies—meet the demands of the industry.”
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.
Low Voltage 0402 MLCCs now in ESA QPL
Exxelia ranges of low voltage MLCC for surface mounting, CEC19 and CNC19, have achieved the Qualified Part List (QPL) status under the criteria of the European Space Component Coordination’s (ESCC) 3009/042 and 3009/043 respectively. The case size 0402 QPL-qualified parts are available from 10V to 25V, enabling substantial miniaturization and cost-saving. Dielectrics are based either in the very stable NPO (type 1) or the high capacitance X7R (type 2). CEC and CNC series combine high capacitance values with high thermal and voltage stability. Versions with polymer terminations are also QPL-certified. These ranges of versatile chip capacitors are intended for use in a wide variety of aerospace applications requiring the highest level of reliability: satellites, launch vehicles, payloads, etc. CEC19 features: - very stable NPO dielectric - maximum capacitance values: 330pF in 10V, 120pF in 16V and 100pF in 25V, - large operating temperatures: -55°C to 125°C CNC19 features: - high capacitance X7R dielectric - high capacitance rating values: from 68pF to 12nF in 10V, 8.2nF in 16V and 5.6nF in 25V - large operating temperatures: -55°C to 125°C
