PE-0603HFB102ST

Overview

The PE-0603HFB102ST is a surface-mount ferrite bead from Pulse Electronics, designed for high-speed signal line filtering under 1 GHz. It features a 1 kOhm impedance at 100 MHz and operates within a temperature range of -55°C to +125°C. The component has a maximum DC current rating of 100 mA and a maximum DC resistance of 1.6 Ohms. It utilizes an SMD/SMT termination style in a 0603 (1608 metric) package with dimensions of 1.6 mm length, 0.8 mm width, and 0.65 mm height.

Feature Summary

• Provides effective electromagnetic interference suppression for high-speed digital signals
• Utilizes a compact 0603 surface-mount footprint for space-constrained designs
• Ensures stable performance across a wide industrial temperature range

Applications

• High-speed data interface protection
• Clock signal line filtering
• USB and HDMI port noise suppression

Procurement Notes

Verify the specific impedance tolerance and DC resistance values against the official manufacturer datasheet prior to integration. Confirm that the 100 mA current rating aligns with the target circuit's operational requirements. Ensure the 0603 package dimensions match the PCB land pattern specifications to guarantee proper soldering and mechanical stability during assembly processes.

Selection Notes

Select this component when designing circuits requiring attenuation of high-frequency noise on single-line signal paths. The 1 kOhm impedance value is suitable for suppressing broadband interference without significantly affecting the desired signal integrity. Consider the 100 mA current limit to ensure the component does not saturate or overheat during normal operation, maintaining consistent filtering performance.

Part Context

This ferrite bead belongs to Pulse Electronics' passive component portfolio, specifically engineered for EMI mitigation in electronic assemblies. It complements other signal conditioning components by providing targeted frequency-dependent resistance. The product is part of a broader series of chip beads designed to meet modern electronics demands for compact, reliable noise control solutions in consumer and industrial devices.

Replacement Considerations

Cross-reference with other 0603 ferrite beads offering 1 kOhm impedance and similar current ratings. Verify compatibility regarding physical dimensions and thermal characteristics before substitution.
