Looking for Variable Resistor/Potentiometer with range from (approx) 10Ω to 1KΩ -- do they exist?

Hello, I'm looking for either a variable resistor or potentiometer with a range of, say, 100<span class="colour" style="color: rgb(51, 51, 51);">Ω to 1KΩ. Everything I'm finding, even when filtering results, has ranges of, for example 10Ω to 2MΩ, I just don't need that much range and suspect it would be more diffitul to finely tune my requirements with such a high range of resistance. Does a lower range variable resistor exist?</span><br> <br> For reference, some items I've looked at: * [https://www\.lcsc\.com/product\-detail/Variable\-Resistors\-Potentiometers\_BOCHEN\-Chengdu\-Guosheng\-Tech\-3296W\-1\-102\-8mm\_C2766201\.html](https://www.lcsc.com/product-detail/Variable-Resistors-Potentiometers_BOCHEN-Chengdu-Guosheng-Tech-3296W-1-102-8mm_C2766201.html) * [https://www\.lcsc\.com/product\-detail/Variable\-Resistors\-Potentiometers\_BOCHEN\-Chengdu\-Guosheng\-Tech\-3296W\-1\-100\_C118900\.html](https://www.lcsc.com/product-detail/Variable-Resistors-Potentiometers_BOCHEN-Chengdu-Guosheng-Tech-3296W-1-100_C118900.html) * [https://www\.lcsc\.com/product\-detail/Variable\-Resistors\-Potentiometers\_BOCHEN\-Chengdu\-Guosheng\-Tech\-3362P\-1\-102\_C118947\.html](https://www.lcsc.com/product-detail/Variable-Resistors-Potentiometers_BOCHEN-Chengdu-Guosheng-Tech-3362P-1-102_C118947.html) Thank you!

The datasheets cover the whole product range of each particular series. They are not well written because they do not make it clear how the generic datasheet  relates to each individual part in the series. For example, the reference to 50R - 2MR in: [https://www\.lcsc\.com/product\-detail/Variable\-Resistors\-Potentiometers\_BOCHEN\-Chengdu\-Guosheng\-Tech\-3296W\-1\-102\-8mm\_C2766201\.html](https://www.lcsc.com/product-detail/Variable-Resistors-Potentiometers_BOCHEN-Chengdu-Guosheng-Tech-3296W-1-102-8mm_C2766201.html) is telling you that there are parts available in this range with end to end resistances of from 50R up to 2MR. The individual part resistances are as given in the LCSC product pages by the 102 or 100 suffixes and the product descriptions. The 3 digit suffix is read (in Ohms) as: AB * 10^C so 100 = 10 * 10^0 = 10 * 1 = 10 and 102 = 10 * 10^2 = 10 * 100 = 1000 A further example: 220k would therefore be 224 = 22 * 10^4 = 22 * 10^4 = 22 * 10000 = 220000. :)
