Hi all, I'm mostly just flailing around looking for ideas. I want to make a small heater. Say 1-3 Watts, with resistance in the 10-100 ohm range. (At the moment I'm not quite sure how much power I'll need, it may be less than a watt.) This will be for a pulsed heat capacity measurement. (heat pulse -> measure temperature rise, rinse and repeat.) So it's important for the temp sensor and heater to have a small heat capacity themselves. My first thought was a TO-220 pack resistor.
1.91 grams (outta the box) Trim tab... 1.32 g Trim leads 1.21 g That's still much too big. Now minco has heaters on kapton tape that might work. HK5186R25.0L12 is a one watt heater with a 1/2" diameter And a hole in the center. The 1/2 inch is a bit more than I wanted. I'm looking for other ideas. (?) (Zener diode?, surface mount resistor?...) Well also a transistor as heater, but I'm going to start a second thread for that topic.thanks, George H.
