BPURNS TC73 - Trimming Potentiometer handbook
The document is about the RoHS Directive 2002/95/EC, which includes the specifications of the TC73 trimming potentiometer. It provides information on the electrical characteristics, environmental characteristics, and physical characteristics of the product. The standard resistance range of the trimming potentiometer is 500 to 1 megohm, with a resistance tolerance of ±30%. The minimum resistance is ≤ 1K Ohms with a maximum of 20 ohms. The contact resistance variation is 5% maximum, and the resolution is infinite adjustment. The product has a power rating of 0.05 watt at 50 °C, a temperature range of -25 °C to +85 °C, and a temperature coefficient of ±250 ppm/°C. It is also humidity resistant up to 95% RH for 500 hours. The trimming potentiometer is compatible with reflow processing and pick and place equipment, and it is supplied in 8 mm embossed tape for automatic assembly. It features a carbon element and is RoHS compliant.
