Supertransferred hyperfine interactions between the Cu^{2+} unpaired electron and the ^{105}Pd nuclei in the Sr_2Pd_{0.99}Cu_{0.01}O_3 ceramic were studied by the EPR method. The spectrum of isolated -Pd-O-CuO_2-O-Pd- units (g_∥ = 2.280±0.001; g_⊥ = 2.040±0.001; A_∥(^{63}Cu) = 13 mT±0.1; A_∥(^{65}Cu) = 13.9 ±0.1 mT; A_⊥(^{63,65}Cu) = 0.0 mT) overlaps the signal from small groups of exchange coupled Cu^{2+} ions (g_∥ = 2.278±0.002; g_⊥ = 2.041±0.001). The isotropic contribution was shown to dominate in the Cu-Pd supertransferred interactions (A_∥(^{105}Pd) = A_⊥ (^{105}Pd) = 1 mT = a_{iso} Pd).
