Power electronics design in railway applications presents
unique environmental, mechanical and electrical challenges
in the selection of power resistor components and assemblies.
The selection of resistors must be engineered to take these
factors into account. Why?
• Resistors must be carefully chosen to meet the specific
performance requirements including factors like power rating,
power density, accuracy, stability, short-term overload
capacity, capacitance and inductance and thermal de-rating.
• In addition, heat dissipation, electrical isolation and other
requirements often call for specialized packaging solutions.
Working with TE Connectivity
• We provide you with reliable technology for high safety
railway applications.
• As a global company, we operate wherever you do and we can
support you worldwide through a single account management
program, which simplifies design and sourcing for you.
• Through our global manufacturing network in 25 countries,
we can balance e.g. exchange rate volatility to offer you
competitive pricing for your local market needs.
• Depending on your application, you can either choose a
field-proven component from our standard resistor portfolio.
• Or, if you need a custom solution, our experienced field
engineering and design team works closely with your
engineering personnel to meet your exact requirements.
• We conduct in-house testing in our own R&D laboratory.
• We design tests in conjunction with your specifications
to include cyclic rated power and overload testing, adiabatic
(single shot and frequency) testing, environmental, mechanical
and repetitive pulse testing. Qualification testing is carried
out to a proven procedure and the product development
stages are well documented and approved by a design
approval team.
• We offer 3D modeling of the product so you have an
understanding of what the product will look like from the
start of the project.
• TE supplies quick turnaround samples.
