对于基于印刷电路板的设计，平面螺旋电感比片式或线圈电感便宜。设计螺旋电感的准确性很重要，因为一旦将电感安装在印刷电路板上，就很难对其进行修改。一些公式可用于单层设计中电感小于100nH的RF-IC应用的螺旋电感的计算。对于需要10μH以上电感的家庭电话网络联盟(HPNA)或射频电信设计的应用，还没有发表的论文或报告准确计算多层大值螺旋电感。
Planar spiral inductors are less expensive than either chip or coil inductors for PCB (printed-circui-board)-based designs. Accuracy in designing a spiral inductor is important because it is difficult to modify the inductor once you have built it on the PCB. Some formulas are available for calculating the spiral inductor for RF-IC applications with inductance of less than 100 nH on a single-layer design. For the application of HPNA (Home Phoneline Networking Alliance) or RF-telecom designs, which need inductances of more than 10 μH, no published paper or report accurately calculates spiral inductors with a large value in multiple layers.
