C transformer core is a high-performance magnetic structure built by winding premium cold-rolled silicon steel strips. Its name comes from its distinctive “C”-shaped cross-section. The design uses two mirrored C-shaped halves that snap together to complete the magnetic loop—this is a huge plus for assembly, as you can slide pre-wound coils directly onto the core. It’s basically the efficiency of a continuous wound core but with way more flexibility. We focus heavily on the precision-grinding of the joint faces; this extra step is what actually slashes magnetic resistance, noise, and flux leakage. The result is a much tighter, more compact core that hits high permeability without eating up extra space.

C Transformer Core isn’t just a component—it’s about maximizing magnetic flux. We manufacture these using premium CRGO silicon steel (from 0.05mm ultra-thin up to 0.35mm), and we deliver cores optimized for low loss and high saturation. Our process combines specialized stress-relief annealing with precision grinding to meet the rigorous demands of modern power electronics.
Our C transformer cores are built for tough, high-performance roles:
We don’t just ship units; we ship performance you can trust.
Custom service: OEM & ODM
We don’t just sell standard stock. If you’ve got a specific blueprint or a tricky magnetic requirement, we’ll build it for you. From simple private labeling (OEM) to deep-level ODM engineering, we make sure the core fits your housing and power specs exactly as you planned.
Provide Sample service
Nobody wants to guess before a big order. That’s why we offer a sample program. It lets your team run their own bench tests to verify B-H curves or build quality before we ever kick off a full production run.
Timely Delivery
We keep things realistic so you aren’t left waiting on your project:
Sample: Usually takes 8 to 10 days.
Batches: We ship in 8 to 30 days, depending on how big the pull is.
