POWER RESISTORS January, 2008 Bourns Manufacturers Representatives Corporate Distributor Product Managers Americas Sales Team Asia Sales Team Europe Sales Team Bourns Internal Bourns Plant Managers 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. The relevant changes are illustrated below: 5.08 (0.2) 2.54 (0.1) 5.08 (0.2) B 0.9906 (0.039) DIMENSIONS = MILLIMETERS (INCHES) Previous Data Sheet 5.3 (0.208) 5.3 (0.208) 2.7 (0.106) 0.76 (.03) 0.58 (.02) 1.2 (0.047) DIMENSIONS = MILLIMETERS (INCHES) TOLERANCE = 0.58 (.02) New Data Sheet ±0.3 (±0.012) N0803 Bourns® Fixed Resistors Product Line Announces Improvements in Power Resistor Specifications January, 2008 Page 2 of 2 The following matrix summarizes the differences in dimensions: Parameter Length Width Thickness Previous Datasheet (mm) 5.08 2.54 0.99 The changes are valid from week 50, 2007 onwards.
