TWE085421925SDG RJ45 Jack, Tab Down

The TeleWire Technology TWE085421925SDG is a 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

  • −40 °C to +85 °C — beyond what a commercial-grade jack is rated for.
  • Shielded shell without EMI fingers — grounding becomes a layout decision, not a mechanical one.
  • No integrated magnetics — pair it with the discrete transformer your PHY vendor specifies.
  • Tab-down latch — suits an inverted board where the release faces the operator.

Typical application: process and utility equipment installed in unconditioned plant rooms.

Pricing for the TWE085421925SDG ranges from $0.50 to $3.00 USD depending on order quantity and configuration, with volume tiers available on request.

Validate the TWE085421925SDG 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.
