Overview
The TX1681NL is a signal transformer manufactured by Pulse Electronics, designed for Power Line Communication (PLC) applications. It supports a wideband frequency range of 3 MHz to 30 MHz and is engineered in compliance with IEC-62368 standards for 250V main supply isolation. The component features a turns ratio of 1:1 with a center-tapped secondary configuration and provides 1500 VRMS insulation voltage. This module facilitates data transmission over power lines while maintaining electrical safety and signal integrity within the specified operational bandwidth.
Feature Summary
- Supports wideband PLC operation from 3 MHz to 30 MHz
- Complies with IEC-62368 safety standards for 250V mains
- Provides 1500 VRMS isolation voltage
- Features 1:1 turns ratio with center-tapped secondary
Applications
- Power Line Communication (PLC) systems
- Data transmission over AC power lines
- Smart metering infrastructure
- Home automation networks
Procurement Notes
Verify that the specific application requires the 3 MHz to 30 MHz bandwidth and 1500 VRMS isolation rating. Confirm compatibility with IEC-62368 safety requirements if used in mains-connected equipment. Ensure the PCB footprint matches the surface-mount package dimensions provided in the official datasheet. Cross-reference the manufacturer part number to avoid confusion with similar LAN transformers.
Selection Notes
Select this component when designing PLC interfaces requiring robust isolation for 250V environments. The wide frequency range suits various PLC standards operating above 1 MHz. Consider the center-tapped secondary design for differential signaling architectures. Validate thermal performance within the intended operating temperature range before finalizing the design.
Part Context
TX1681NL belongs to the Pulse Electronics portfolio of audio and signal transformers. It is distinct from standard Ethernet LAN transformers like the HX5181NL or H1062NL, which operate at lower frequencies (up to 125 MHz for Gigabit Ethernet). This model is specialized for PLC magnetics rather than traditional network cabling applications.
Replacement Considerations
Consult the official Pulse Electronics substitution guide for verified alternatives. Generic PLC transformers may not match the specific 1500 VRMS isolation or wideband frequency response required for IEC-62368 compliance.
