Bearing only the part number 1SV249, this 62.1 KB PDF is indexed among schematics but is most likely a component data sheet. The 1SV prefix belongs to Toshiba's varactor diode family under Japanese 1S diode numbering. Inside you would typically find maximum ratings, capacitance-versus-bias graphs and outline dimensions. Use it to check polarity and marking on a suspect part and to make sure any equivalent offers a similar capacitance range for the tuning circuit it serves. Open it in any PDF viewer.
