Measured 100kΩ Resistor Array: Power Margin of the 1608 Package and Design Pitfalls of 5% Tolerance

A resistor array with a nominal value of 100kΩ, 1608 package, and ±5% tolerance actually has a measured power margin of less than 60% of its nominal value in a 25°C environment—this is not an isolated case, but a miniature of pitfalls encountered by engineers in bulk. When 5% tolerance meets a compact package, is your design margin really sufficient? This article takes typical resistor arrays such as EXB-E10C104J as an entry point, combining measured data with engineering experience to dissect the hidden risks of 1608 package resistor arrays. Interpretation of Resistor Array Basic Parameters: …
