TE Series - 4 Port Modules

Features

  • Low profile (5.8mm) and light weight (4.0 g) 10/100Base-T Quad Port isolation transformer modules designed to support four single or double stacked RJ-45 connectors
  • SMD packages facilitate pick and place compatibility and speed of placement
  • Modules meet requirements of IEEE 802.3u and ANSI X3.263
  • Consistent and reliable co-planarity
  • Excellent quality at extremely competitive price due to high volume production
  • Manufactured in ISO-9001 approved facility
  

Electrical Specifications @ 25°C

Inductance: 350µH minimum @ 100kHz, 100mV, 8mA
Leakage Inductance: 0.4µH @ 1 MHz
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.

Applications

10/100BaseT Quad transformer modules contain transmit and receive isolation transformers to maintain consistent wave shape and suppression of common mode noise while providing equipment isolation per IEEE 802.3. High impedance common mode quad chokes for additional EMI suppression have been added on some models as required for FCC and CISPR 22 Class B certification.
