PM2003-600

Overview

The PM2003-600 is a single-line ferrite chip manufactured by Bourns Inc. It features a 3612 (9131 Metric) package with dimensions of 9.10mm length and 3.10mm height. The component provides an impedance of 90 Ohms at 100 MHz and operates within a temperature range of -55°C to 125°C. It is designed for high-frequency noise suppression in electronic circuits.

Feature Summary

• Provides effective attenuation of high-frequency electromagnetic interference signals
• Utilizes a compact surface-mount footprint for dense circuit board layouts
• Maintains stable electrical characteristics across a wide industrial temperature range

Applications

• High-frequency noise suppression in signal lines
• Electromagnetic interference filtering in consumer electronics
• Signal integrity enhancement in digital communication interfaces

Procurement Notes

Verify the specific suffix designation, as the PM2003-600-RC variant explicitly denotes RoHS compliance. Confirm the package type matches the required 3612 footprint. Check current availability status, as some listings indicate this part may be obsolete or discontinued. Ensure the impedance specification aligns with the target frequency requirements of the design.

Selection Notes

Select this component when a 90 Ohm impedance at 100 MHz is required for noise control. The 3612 package size offers a balance between performance and board space. Consider the operating temperature range if the application involves extreme environmental conditions. Verify compatibility with the specific trace width and current carrying capacity needs of the circuit.

Part Context

This ferrite bead belongs to the PM2000 series from Bourns Inc., which focuses on passive components for signal conditioning. The series is engineered for applications requiring reliable high-frequency attenuation. Ferrite chips in this category are commonly used to suppress common-mode noise without affecting the desired signal bandwidth.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Engineers should consult manufacturer cross-reference tools or datasheets for equivalent ferrite beads with matching impedance curves and package dimensions.
