TE Series - Mini Dual Port

Preliminary Data Sheet


  • Low profile (5.8mm) and lightweight(3.5 g) the 10/100Base-T Dual transformer modules facilitate pick and place compatibility and speed of placement
  • Dual port modules meet requirements of IEEE 802.3u and ANSI X3.263
  • Consistent and reliable co-planarity
  • Manufactured in ISO-9001 approved facility

Electrical Specifications @ 25°C

Inductance: 350µH minimum @ 100kHz, 100mV, 8mA
Leakage Inductance: 0.4µH @ 1MHz
CW/W: 20pF Typical
Minimum Isolation Voltage: 1,500 Vrms

Operating Temperature: 0° to +70°C
Storage Temperature: -25°C to +105°C
Standard packing: Tape and reel

Quality and consistency is guaranteed through 100% testing of the specified parameters for primary inductance, leakage inductance, turns ratio, DC resistance and Interwinding capacitance. This ensures that the return loss and pulse wave shape requirements can be fully maintained. Additionally, all parts are tested for 1,500V minimum isolation.
