PREMO Unveils Isolated Coupling Transformers for Power Line Communication


PREMO, a manufacturer of RFID magnetic sensors, Inductive couplers, and power magnetic components completes its range of signal transformers with this SMD PLC-LW series. Providing a more competitive (low cost) product using Linear Winding versus Toroidal winding.

This SMD isolation transformer 1:1 has been designed for coupling/decoupling signals for power lines communication according to IEC 15118 and IEC 618511 for charging system communication V2G & V2V.

Main features for PLC-LW Series:

The PLC-LW Series, designed with NiZn magnetic core provides minimum insertion losses in the wide frequency band 130 MHz and is able for communication up to 100MHz:

  • SMD coil former technology (reduced size, smaller than toroid version)
  • Fully automated production to answer to EV/PHEV global development (millions of parts)
  • Ultra-Low insertion losses (< 1dB) on 100120 Ohm load (230MHz PLC equivalent network load)
  • Highly reproducible performances (better than toroidal solutions)
  • Wide temperature range (40 t0 +125ºC)
  • UL94 and ROHS materials
  • 13” Tape & Reel packaging
  • AECQ200 Automotive qualified

Suitable for HPGP (HomePlug Green PHY, 10Mbps), HPAV (80Mbps) and HPAV2 (Gbps), to operate above 85MHz.

HPGP is an innovative variant of HomePlug powerline communications technology. HomePlug Alliance certified, fully interoperable with IEEE1901/HPAV, Operating frequency (2 – 28 MHz) is well above switching noise generated by EV charging equipment, low power, low cost, robust performance @ 10 Mbps.

PLC-LW series are safety solutions (isolated coupling transformers) with two different configurations for matching to a wide range of PLC modem chipsets such as Qualcomm, ST, Maxim, NXP, etc.
