Compounds belonging to the R$_2$Fe$_3$Si$_5$ series exhibit unusualsuperconducting and magnetic properties. Although a number of studies have beenmade on the first reentrant antiferromagnet superconductor Tm$_2$Fe$_3$Si$_5$,the physical properties of Yb$_2$Fe$_3$Si$_5$ are largely unexplored. In thiswork, we attempt to provide a comprehensive study of bulk properties such as,resistivity, susceptibility and heat-capacity of a well characterizedpolycrystalline Yb$_2$Fe$_3$Si$_5$. Our measurements indicate that Yb$^{3+}$moments order antiferromagnetically below 1.7 K. Moreover, the system behavesas a Kondo lattice with large Sommerfeld coefficient ($\gamma$) of 0.5~J/Yb molK$^{2}$ at 0.3 K, which is well below T$_N$. The absence of superconductivityin Yb$_2$Fe$_3$Si$_5$ down to 0.3 K at ambient pressure is attributed to thepresence of the Kondo effect.Comment: 10 pages, 3 figures, tex document. A fuller version has appeared in  PRB. Here we have omitted the figures showing the crystal structure and the  fitting of the X-ray pattern. Also the table with the lattice parameters  obtained from fitting has been remove
