The primary inductance for any configuration can be calculated as: 2 Primary Inductance (µH MIN) = 2.4 * (Primary_Turns) 2. The above base part numbers (PA08XXNL) are available from stock. 3. It is possible to add a small gap to the transformer. Gapped transformers are non-standard and can be made available upon request, but are not typically available from stock. To request a gapped version of the transformer, add a suffix “G” to the base number (i.e. PA0801GNL or PA0801.004GNL etc.). The nominal inductance with the a gap can be calculated as: 2 Primary Inductance (µH nominal) = 0.69 * (Primary Turns) 4. It is possible to add a primary side aux. winding to any of the above configurations as shown in the schematics. Transformers with primary size aux. windings are non-standard and can be made available upon request, but are not typically available from stock. The primary aux. winding can be between 2 and 16 turns. To add a primary aux. winding to a given base, use the extension .0XX. For example, to add a 4T aux. winding to the base part number PA0801NL, use the part number PA0801.004NL. To add a 16T aux. winding, use the part number PA0801.016NL. 5. Optional Tape & Reel packaging can be ordered by adding a “T” suffix to the complete part number (i.e. PA0801 becomes PA0801T for no AUX - PA0801.009NL becomes PA0801T.009NLT for 9T AUX).
