Low DCR SMD Common Mode Choke STC09 Series High Saturation Core for DC-DC Conversion and Input Filtering
STC09 Series SMD Common mode inductor,surface mount toroidal coils and common mode toroidal choke,25uH to 2500uH
The STC09 series SMD toroidal common-mode inductor uses a high-frequency design and high saturation core material. The inductance range covers 25µH to 2500µH. The toroidal closed magnetic circuit structure effectively reduces EMI radiation. The low DCR reduces power loss. The SMD package supports automated placement, compatible with SMT production lines. It is widely used in electronic appliances, DC-DC conversion (parallel mode), isolation coupling, input filtering (series mode), and EMI/RFI suppression.

Q: What is the inductance range of the STC09 series?
A: The STC09 series covers an inductance range from 25µH to 2500µH, covering a wide range of applications from smaller inductance values to medium inductance values. Lower inductance values are suitable for high-frequency filtering applications, while higher inductance values are suitable for low-frequency power filtering. Selection is flexible.
Q: What are the advantages of the high-frequency design for this product?
A: The high-frequency design optimises core material and winding structure. It allows the product to maintain high common-mode impedance and stable filtering performance at higher switching frequencies. The STC09 series offers a smaller inductance range (starting from 25µH), making it especially suitable for high-frequency switching power supplies and high-speed signal line EMI filtering applications.
