Product Overview
The Pulse Engineering PE-64103 is a 16-pin DIP LAN isolation transformer module engineered for Ethernet network interfaces and pulse transmission lines. Built with a 1:1 turns ratio and 100 µH minimum open-circuit inductance, it provides signal coupling, noise rejection, and electrical isolation across vintage network hardware and specialized digital communications circuitry.
Key Features
- Dual in-line 16-pin through-hole package (DIP-16)
- 1:1 turns ratio for network signal coupling
- 100 µH minimum open-circuit inductance (OCL)
- 500 Vrms isolation rating
- 0.20 to 0.30 ohm typical DC resistance (DCR)
- Marked date code 9344-W
Applications
- Soldering direct replacement transformers onto vintage 10BASE-T and Ethernet adapter cards
- Isolating balanced digital pulse signals on custom breadboards and microcontroller projects
- Restoring legacy industrial networking interfaces and telecommunications gear
- Benchtop RF and pulse coupling experiments requiring compact 1:1 isolation
Frequently Asked Questions
What is the pin configuration and package format?
This module uses a standard 16-pin through-hole DIP package with standard row spacing, making it compatible with through-hole circuit boards and breadboard sockets.
What isolation rating does this transformer provide?
The PE-64103 is rated for 500 Vrms galvanic isolation across its windings, isolating connected digital circuitry from external line surges and common-mode ground noise.
Why buy this specific unit instead of taking a chance on an unknown surplus lot?
You receive the exact unused, individually inspected component photographed here with clean pins and verified markings, eliminating the risk of mismatched revisions or bent leads. Shipping is $8 flat rate, free once the order passes $28, and orders leave our Idaho warehouse the same or next business day.
Real copper wire wound into miniature cores to solve clean-signal headaches before modern integration swallowed it all whole. Plug it into the circuit board, bridge the isolation gap, and let your legacy hardware talk again.
