The Reliable Source . .. FERROPERM for High Quality Inductors and Transformers INDUCTORS AND TRANSFORMERS from FERROPERM UK Ltd. FERROPERM offers a manufacturing capability for the production of most types of high quality inductors and transformers, including surface mounting types. Toroidal types and wave-wound types are particular specialities. Transformers are all produced as custom designs (see page 16). Inductors are produced as custom designs (see page 15) and in standard ranges which are presented in this catalogue. A highly flexible production facility ensures short lead times on custom designs as well as standard products. We can produce designs for your applications or we can manufacture to your own designs. Rather than trying to list all the types of inductors and transformers FERROPERM can produce, it is easier to list types not made: 1. ``Mains'' (50 or 60Hz) power transformers. 2. Inductors and transformers with any dimension larger than about 300 mm. UK3 Ferroperm UK Ltd. Wrexham. LL14 6HA.

Just send us your drawings! If you would like us to design inductors to meet your requirements, please send us the following information. If you do not have all the information available, please just give what you can. 1. Specify the application. (For example, Energy Storage Choke for a Switched Mode Power Supply). Please give as much information as you can. 2. Specify the maximum dimensions of the space you have available for the inductor. 3. Specify if you require surface mounting or through-hole mounting. 4. If you have a preference for a particular hardware design (for example rod or toroidal), please state it. 5. Specify your estimated requirements of quantities and delivery dates both for short term and long term. This is important because it may influence what hardware is specified for the design. 6. If you have a target or maximum price level, please state it. 7. Specify maximum average direct current flow. 8. Specify maximum peak current flow. 9. Sketch or describe any alternating current waveform (other than interference current). If the waveform is variable, please specify the extremes. FOR ENERGY STORAGE CHOKES (INDUCTORS): 10. Specify inductance and widest acceptable tolerance at near zero current, at maximum average current and at maximum peak current. FOR ALL OTHER INDUCTORS: 10. EITHER specify inductance and widest acceptable tolerance OR specify minimum required impedance at particular frequencies or sketch a graph of minimum required impedance versus frequency. 11. Specify if common mode (current compensated) design is required. (Examples of common mode chokes are shown on page 13.) 12. Specify maximum working voltage between windings if common mode. 13. If this working voltage is a.c., please specify the frequency. UK3 Ferroperm UK Ltd. Wrexham. LL14 6HA. Tel +44 1978 823 990 Fax +44 1978 810 128 15 CUSTOM TRANSFORMERS from FERROPERM UK Ltd. If you already have transformer designs, we will be pleased to quote for their manufacture. Just send us your drawings! If you would like us to design transformers to meet your requirements, please send us the following information. If you do not have all the information available, please just give what you can. 1. Specify the application. (For example, Switched Mode Power Supply (SMPS) in an instrument). Please give as much information as you can. 2. Indicate by a schematic or describe how the transformer is driven and used. (For example, push-pull FET drive in a SMPS). Please give as much information as you can. 3. Draw a schematic of all windings with turns ratios and widest acceptable tolerance of turns ratios. Indicate polarity of windings where it is important. For windings with one or more taps between the ends, please make clear what turns ratios are required for each section of the winding! 4. Specify what voltage isolation requirements there are between all windings. 5. Draw or describe the voltage waveform which will be applied to the primary winding. If the waveform is variable, please specify the extremes. 6. Specify maximum working currents to be drawn from all secondary windings. 7. If occasional overload conditions have to be met, please specify these seperately. 8. Specify the maximum dimensions of the space you have available for the transformer. 9. Specify if you require surface mounting or through-hole mounting. 10. If you have a preference for a particular hardware design (for example ETD, RM or toroidal), please state it. 11. Specify your estimated requirements of quantities and delivery dates both for short term and long term. This is important because it may influence what hardware is specified for the design. 12. If you have a target or maximum price level, please state it. UK3 Ferroperm UK Ltd. Wrexham. LL14 6HA. Tel +44 1978 823 990 Fax +44 1978 810 128 16 INDUCTORS AND TRANSFORMERS from FERROPERM UK Ltd.
