TWE085421925S4L3H RJ45 Jack, Tab Up, Yellow/ Green LED

The TeleWire Technology TWE085421925S4L3H is a EMI-finger shielded RJ45 jack. 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

  • Yellow/ Green LEDs — wired to the host PHY, not to internal logic.
  • −40 °C to +85 °C — beyond what a commercial-grade jack is rated for.
  • No integrated magnetics — pair it with the discrete transformer your PHY vendor specifies.
  • EMI grounding fingers — chassis bond made at the bezel, not through the PCB.

Typical application: industrial gateways and factory-floor equipment rated beyond the commercial range.

Pricing for the TWE085421925S4L3H ranges from $0.50 to $3.00 USD depending on order quantity and configuration, with volume tiers available on request.

Validate the TWE085421925S4L3H 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.
