Bourns® Fixed Resistors Product Line Announces
Improvements in Power Resistor Specifications
As part of Bourns commitment to product excellence, we are announcing an improvement in the
dimensional accuracy of our CHF surface mount power resistors.
The marking on the surface of the chip has also been improved with a characteristic Bourns logo. The
orientation of the logo is useful for determining the position of the input terminal.
The model CHF2010 will be the first model to implement these changes. The datasheet has been
updated to reflect the changes.
