      6V ac 1 Output Through Hole PCB Transformer, 0.5VA
      Product Details

      Transformers PCB Mount, Short Circuit Proof, VB & PT Series

      230Va.c. 50 to 60Hz primary
      Single or twin secondary windings for series or parallel connection (For conformance reasons,0.35 to 3.2VA transformers with 2 x 15 and 2 x 18V outputs and all transformers with 2x 24V outputs should not have their secondaries connected in series as this means they will not meet the VDE 0550 approval)
      VB series (0.35 - 3.2VA) are inherently short circuit proof
      PT series (4.5 - 22VA) are protected by internal PTC device
      Compact design
      Vacuum epoxy resin moulded to UL94-V0 rating
      Double section glass fibre reinforced polyamide bobbins
      100% electrical and flash tested
      High efficiency and low temperature rise
      Low inter-winding capacitance
      Low radiated noise
      Extra fixing holes for secure boarding mounting on 4.5VA and above
