TG74-1406P1RLTR

Pulse Transformers Overview

The TG74-1406P1RLTR is a surface-mount LAN isolation transformer module designed for 10BASE-T applications. It features a single-channel configuration with a 1:2 turns ratio, supporting 1CT:1CT transmitter and 1CT:2CT receiver connections. The component operates within a temperature range of -40°C to +85°C and provides 1.5 kV insulation voltage. Key electrical parameters include an inductance of 25 µH and a maximum DC resistance of 300 mOhms. It utilizes an SMD-16 package with gull-wing terminals, measuring 12.7 mm in length, 7.11 mm in width, and 5.08 mm in height.

• LAN port isolation modules

Pulse Transformers Procurement Notes

Verify the specific suffix P1RLTR against the official HALO Electronics datasheet to confirm pinout compatibility and RoHS status. Ensure the ordering quantity aligns with factory packaging constraints, typically requiring multiples of the reel quantity. Cross-reference the manufacturer part number with authorized distributor catalogs to confirm current availability and lead times prior to finalizing procurement orders.

Pulse Transformers Selection Notes

Select this component for designs requiring dedicated 10BASE-T isolation rather than higher-speed standards like 10/100BASE-TX. Confirm that the 25 µH inductance value meets the specific impedance matching requirements of the target PHY transceiver. Verify that the SMD-16 footprint dimensions fit within the available PCB area and that the thermal operating range covers the intended environmental conditions.

Pulse Transformers Part Context

This part belongs to the TG-10BT series of LAN isolation transformers manufactured by HALO Electronics. It is distinct from other variants such as the TG74-1406N1RLTR, which may differ in internal winding configurations or filtering capabilities. The product line focuses on providing reliable galvanic isolation for legacy Ethernet physical layer interfaces in compact surface-mount packages.

Pulse Transformers Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Users should consult the official HALO Electronics catalog for direct equivalents within the TG-10BT series or verify cross-reference data through authorized distributor channels before attempting substitution.
