H1601CG LAN 10/100 Base-T Pulse Transformer | Antminer C87 Control Board Repair
The H1601CG is a LAN 10/100 Base-T pulse transformer used in the Ethernet communication circuit of the Antminer C87 control board. When this component fails, the miner loses network connectivity — it won't appear on the network dashboard or respond to configuration commands despite the hashboards functioning normally. The H1601CG provides 350µH primary inductance and mounts via SMD pads, making it a straightforward replacement during control board repair.
H1601CG Pulse Transformer: Ethernet Signal Isolation for Antminer C87
Pulse transformers in Ethernet circuits serve two critical functions: they provide galvanic isolation between the miner's internal circuitry and the external network, and they match impedance for reliable 10/100 Mbps data transmission. A degraded H1601CG causes intermittent network dropouts, reduced data throughput, or complete network failure on the C87 control board. The surface-mount package (12.70mm × 7.10mm, 6.20mm height) matches the original component footprint precisely.

Antminer C87 Control Board Network Repair
If your Antminer shows "miner not found" on the network while hashboards are powered and fans are spinning, the control board's Ethernet circuit is a likely culprit. Test by swapping the control board with a known-good unit first. If the replacement board resolves the issue, inspect the original board's H1601CG transformer for physical damage or cold solder joints. Desolder the failed component with a hot-air station, clean the pads, and solder the new H1601CG. For other control board replacements across Antminer models, see the Antminer L9 CV1835 Control Board, the S21XP CBK Control Board, or the Whatsminer CB6 V9 Control Board.
