Depending on infomation needed a compromise has to be found. A codification can be used to identify case size + configuration and number of resistors. See table below. E.g. PRAHT100I4-4K75BWGTA (Part number has more than 18 digts): PRAHT100I4 must be replaced by PRAHT17 = PRAHT17-4K75BWGTA (2) When the last digit(s) of the ohmic value is (are) 0, it (they) can be omitted. E.g.: PRAHT100I4-2K20BWGT can be ordered under PRAHT100I4-2K2BWGT PRAHT100I4-1K00BWGT can be ordered under PRAHT100I4-1KBWGT (3) N termination for temperature up to 200 C.
