Benefits of planar technology vs. wire-wound?
Updated: May 10, 2018
Standex Electronics planar magnetics include planar transformers and planar inductors available in a variety of standard core sizes with custom configurations. As more and more industries begin to feel the push toward higher efficiency and performance along with miniaturization, the planar transformer continues to emerge as an alternative to wire-wound transformers.
Low package profile and weight relative to wire wound equivalent
Very efficient high frequency operation, 98-99% to 40kHz – 500kHz (typ)
Low AC Resistance: Minimum skin effect – flat, split windings. Management of proximity effect
Excellent repeatability thanks to pre-tooled components
Low DC Resistance – efficient use of copper
Low Leakage Inductance – interleaving
Easily termination of multiple windings
Standard outlines are compatible with application - specific custom designs
Flat, compact construction allows for effective thermal management
