CB Magnetics — ISO Certificated professional magnetic products manufacturing and integrated solution company. Provides transformer bobbins, bases, wound cores, transformers, chokes, and more. Email [email protected]. Tel +86 755 61124460 (Shenzhen). Has alternate domain custom-magnetics.com. Comprehensive product range across 5 main categories: Magnetic Powder Core (PQ Type, EQ Type, Block, E-type, Toroidal); Transformer Bobbins (ATQ, EC Series, EF/EE, EFD, EI, EP, EPC, ER, RM, PQ, ETD); Toroid Mounts and Headers (Through-hole inductor base, SMD base, RM Transformer Bobbin); Wound Core (Silicon Steel, Amorphous, Nanocrystalline); Custom Transformers (High Frequency, Low Frequency); Custom Inductors (Common Mode choke, Differential mode choke). Custom molding capability. Surface mount toroids designed to reduce cost while improving circuit-board production — works with robotics for substantially faster and more accurate PCB mounting. Wide variety of surface mount (SMD) headers with molded-in gull-wing, Type-C, and J-lead terminals. Molded from thermoplastic high-grade engineering plastics for toroids. Products comply with RoHS and Reach standards. R-type transformer noted for relatively large inrush current — important to reduce inrush current.
