BBSY00100505241Y00

Overview

The BBSY00100505241Y00 is a multilayer ferrite chip bead manufactured by Pulse Electronics, designed for surface-mount technology (SMD/SMT) applications. It features a 0603 (1608 metric) package with dimensions of 1.6 mm in length and 0.5 mm in width. The component provides an impedance of 240 Ohms at a test frequency of 100 MHz, with a tolerance of 25%. It supports a maximum DC current of 400 mA and has a maximum DC resistance of 0.29 Ohms. The device operates within a temperature range of -55°C to +125°C.

Feature Summary

• Provides high-frequency filtering capability for signal lines under 1 GHz
• Compact 0603 footprint suitable for dense board integration
• Multilayer construction for reliable EMI suppression

Applications

• General signal line filtering
• High-frequency noise suppression
• EMI control in compact electronic devices

Procurement Notes

Verify the specific impedance value against official datasheets, as distributor listings may vary between 220 Ohms and 240 Ohms. Confirm the maximum DC current rating of 400 mA matches your circuit requirements. Ensure the 0603 package size fits your PCB layout constraints. Check RoHS compliance status directly from the manufacturer's documentation before procurement.

Selection Notes

Select this component when shielding or low-impedance paths are not required, relying instead on standard ferrite absorption characteristics. Consider the 400 mA current rating to ensure it exceeds the peak operating current of the protected line. Evaluate the 240 Ohm impedance at 100 MHz to confirm effective attenuation for the target noise frequencies. Compare thermal performance within the -55°C to +125°C range against environmental conditions.

Part Context

This part belongs to the BBSY series of multilayer ferrite chip beads from Pulse Electronics. These components are engineered for surface-mount assembly, offering a balance of electrical performance and physical compactness. The series is commonly used in consumer electronics and telecommunications equipment where space is limited and effective high-frequency noise reduction is critical for signal integrity.

Replacement Considerations
