SMT Planar Transformer  
A9845-AL  
Coilcraft’s surface mount planar transformers are ideal for  
applications that require high efficiency in a low-profile  
package.Theyaredesignedtoperforminpush-pulltopolo-  
gies operating at 200 – 300 kHz. The auxiliary winding can  
be used to control input current to PWMs.  
Planar transformers offer high power densities along with  
greatreliabilityandrepeatability.  
The A9845-A has a smaller footprint and lower profile than  
ourotherplanartransformers.Thecircularwindingsprovide  
very low DCR and excellent leakage inductance values.  
To complete your design, Coilcraft offers a wide variety  
of power inductors for use as input and output chokes. To  
request free evaluation samples, contact Coilcraft or visit
