FERRTX Telecom Transformers｜High Bandwidth Isolation for 5G Infrastructure

*UL/CSA/VDE Certified with 10mH Inductance & SMD Compatibility*

Signal Integrity Redefined

FERRTX Customized Telecom Transformers deliver breakthrough performance in modern communication systems. Engineered for >100MHz bandwidth and <1pF interwinding capacitance, they eliminate ground loop noise better than standard Communication Transformers. With surface-mount design and ultra-low leakage inductance (<2% typ.), they enable 50% denser PCB layouts in 5G base stations versus bulky lander transformers.

Core Engineering Advantages

• Triple-Shielded Isolation
  4kV dielectric strength prevents signal degradation in Broadband Internet backhauls

• Wide Frequency Response
  Supports xDSL/ISDN/PoE++ protocols (DC-150MHz)

• Global Safety Compliance
  Single solution for UL, CSA, VDE, BABT certifications

• EMI Suppression
  Reduces common-mode noise by 30dB vs. microphone splitter transformer
