0826-1X1T-43-F Gigabit MagJack 1x1 Tab Up RJ45 ICM 350µH OCL
1. How does the 0826-1X1T-43-F handle EMI and signal cross-talk?
Electromagnetic interference (EMI) is one of the leading causes of EMC certification failures in high-speed Ethernet switches and routers. The 0826-1X1T-43-F utilizes a fully enclosed, nickel-plated copper shield with multiple solder-dipped ground leads that tie directly to the chassis ground. Furthermore, its superior crosstalk suppression (-30 dB min up to 60MHz) and high common-mode rejection ratios isolate internal noise from radiating outside the system.
2. Why is 350µH OCL critical for Gigabit stability?
Maintaining a minimum of 350 µH OCL with an 8mA DC bias ensures that the magnetic core does not saturate when handling DC currents inherent in active data lines. This guarantees signal fidelity, minimizes packet jitter, and protects transceiver physical layers (PHY) from line transients.
0826-1X1T-43-F 1000Base-T Magjack Overview
The Bel Fuse 0826-1X1T-43-F is an industry-standard, high-reliability 1000BASE-T Gigabit MagJack Integrated Connector Module (ICM). Designed for engineers and hardware developers who refuse to compromise on signal integrity and electromagnetic compatibility (EMC), this single-port (1x1), Tab Up through-hole connector integrates precision magnetics directly into the RJ45 housing.
Backed by Bel Fuse's patented technology (US Pat. 7,123,117) and rigorous UL recognition (Files #E196366, #E169987), the 0826-1X1T-43-F ensures seamless data transmission for commercial networking equipment, industrial control systems, and high-speed communication hardware operating from 0°C to +70°C.

Frequently Asked Questions:
Q: Is the Bel Fuse 0826-1X1T-43-F compatible with standard reflow soldering processes?
A: No. This is a Through Hole Mount component designed primarily for Wave Soldering. The recommended peak wave-solder temperature is 260°C maximum for a duration of no longer than 10 seconds.
Q: What is the difference between Tab Up and Tab Down configurations?
A: The Tab Up configuration (such as this model) places the latching tab at the top of the connector port. This layout is typically chosen when the PCB layout requires the Ethernet cable latch to release from the top, or to align with specific enclosure port geometries and internal clearance constraints.
Q: Does this MagJack support Power over Ethernet (PoE)?
A: No, the 0826-1X1T-43-F is rated as Non-PoE. If your application requires power delivery over data pairs (such as PoE, PoE+, or PoE++), please explore Bel Fuse's dedicated PoE-rated MagJack series.
