Frequently Asked Questions
What is the operating temperature range for these resistors?
The operating temperature range is -55 °C to +155 °C.
How low can the standard resistance tolerance be, and what type of resistor achieves this?
Tolerance can reach as low as ± 0.01 %, which is achieved by certain thin film resistors (e.g., on Y type).
What kind of terminations are available for different use cases?
Options include Gold plated or pre-tinned over nickel barrier, depending on whether the application requires solder reflow or other uses.
Are these components compliant with RoHS standards?
They are compliant to the RoHS directive 2002/95/EC. However, Pb containing terminations are not compliant unless exemptions apply.
