TWE09249925S1LOTB1 10/100/1000 Base-T Vertical RJ45 MagJack, Tab Up, Green/ Yellow LED

The TeleWire Technology TWE09249925S1LOTB1 is a 10/100/1000 Base-T shielded RJ45 MagJack with integrated magnetics. It is a TeleWire Technology original design, manufactured in Taiwan.

Design Origin

  • TeleWire Technology original design — tooled and manufactured in Taiwan.
  • Send your footprint — the engineering team will confirm mechanical compatibility.

Selection Notes

  • Vertical (180°) body — cable exits perpendicular to the PCB, not over its edge.
  • 10/100/1000 Base-T — the rate the internal transformer is wound for.
  • Green/ Yellow LEDs — wired to the host PHY, not to internal logic.
  • −40 °C to +85 °C — rated for unheated cabinets across the seasonal swing.

Typical application: outdoor and unheated cabinets where the port exits through a top cover.

Pricing for the TWE09249925S1LOTB1 ranges from $0.50 to $3.00 USD depending on order quantity and configuration, with volume tiers available on request.

Validate the TWE09249925S1LOTB1 on your board first. Samples are available for design validation, and the mechanical drawing gives the footprint before you commit a layout. Request a sample or quotation.
