Measuring and determining 1/f voltage noise over a multiple-year sample requires an operational amplifier and effective 1/f knowledge. This article shows how to identify and determine the actual op amp 1/f voltage noise across a sample size of years and explains why the 1/f voltage noise is a non-issue at higher frequencies. After many years […]

Single-turn potentiometers, encoders excel at rugged industrial apps
TT Electronics announced the addition of three new product families and three series expansions to its variable resistor portfolio. Portfolio additions include one new encoder series and two new single turn potentiometer families, along with the broadening of three existing potentiometer families. These new products are ideal for rugged industrial applications such as welding equipment […]
Thick-film chip resistor arrays comply with AEC-Q200 standard
Bourns, Inc. announced several new AEC-Q200 compliant thick film chip resistor array model families. Bourns designed the new surface-mount model CATxxA-LF, CAYxxA-LF, and CAYxxA-AS series to help increase available board space and reduce costs. Offering long-life protection against many sulfurous environments, the Model CAYxxA-AS series is the first chip arrays from Bourns that meet both the AEC-Q200 […]
