Analyst Opinion (Expert Opinion)

• Despite their performance advantages, planar transformers demand precision manufacturing, advanced materials, and multilayer PCB integration, which significantly raise production costs. Many mid-tier manufacturers struggle to scale efficiently, leading to a market still dominated by a handful of technologically advanced players.
• Unlike traditional wound transformers, planar designs offer less flexibility for high-isolation or custom magnetic configurations, making them harder to adapt across diverse voltage and current requirements. This rigidity constrains their adoption in rapidly evolving applications like renewable energy systems and EV powertrains.
• The premium pricing and long qualification cycles of planar transformers remain a deterrent in cost-conscious markets such as consumer electronics and small industrial systems. Unless manufacturing costs decline or standardization improves, widespread market penetration may remain slower than the pace of innovation.
