Key Features
- 51 µH dual-line ferrite filter suppresses common-mode EMI on differential signal pairs with 4-pin 1812 package
- Low 1 Ω maximum DC resistance minimizes voltage drop and power loss in filtered signal or power lines
- 10 MΩ minimum insulation resistance ensures high isolation between lines in sensitive analog and digital circuits
Applications
The DLW43SH510XK2L is a dual-line common-mode choke used in USB, HDMI, Ethernet, and CAN bus interfaces to suppress common-mode EMI noise without attenuating differential signals. Its 1812 SMD package and 51 µH inductance make it effective for EMI filtering at frequencies from several MHz to hundreds of MHz in consumer electronics, automotive infotainment systems, and industrial communication modules. The 4-pin configuration integrates two line filters in a single component, reducing PCB area compared to discrete per-line chokes.

Frequently Asked Questions
How does the 51 µH inductance of DLW43SH510XK2L help suppress common-mode noise on communication lines?
The 51 µH ferrite inductance presents high impedance to common-mode noise currents typically found in the 1 MHz to 100 MHz frequency range on USB, CAN bus, or Ethernet lines. Differential signal currents flow in opposite directions through the 4-pin winding and largely cancel, so the filter passes differential data with minimal loss while blocking common-mode interference from radiating or entering the circuit.
How much voltage drop does DLW43SH510XK2L introduce at rated line current given its DC resistance spec?
With a maximum DC resistance of 1 Ω per line, the DLW43SH510XK2L introduces a voltage drop of 1 V at 1 A or 100 mV at 100 mA. In low-current signal lines such as CAN bus or RS-485, where line current is typically under 50 mA, the drop remains below 50 mV, negligible for most interface voltage budgets.
Which interface designs should use the DLW43SH510XK2L in place of a single-line ferrite bead?
Differential interfaces such as USB 2.0, CAN bus at 1 Mbit/s, RS-485, and 100 Mbit/s Ethernet benefit from DLW43SH510XK2L instead of two separate ferrite beads. The 4-pin common-mode choke structure matches inductance on both lines by construction, preventing impedance imbalance that causes mode conversion and increases differential insertion loss — a problem common when two discrete beads with ±20% inductance tolerance are placed on paired lines.
