This table is made for thermistor 3950 (can be found on ebay for cheap)
it's caracteristics are : R25℃ ;100KΩ±1% B Value(R25/50℃)：3990K 1% Dissipation Factor(mW/℃)：1.1~1.6 In still Air Thermal Time Constant(S)：10~17 In Still Air Operating temperature range： (-50~+260°C) Dimension： 1.8mm Dia X4.1mm Lead Length ：30mm This table was found on the following blogs: http://cae2100.wordpress.com/2014/03/08/beta3950-thermistor-table-for-marlin/ and http://microfabricator.com/articles/view/id/531ad7e59aad9d3131000000/beta-3950-thermistor-table-for-marlin
