BLE18PS080SZ1D

Chip Ferrite Bead Overview

The Murata Electronics BLE18PS080SZ1D is a surface-mount ferrite chip bead designed for electromagnetic interference suppression in high-current applications. Housed in a compact 0603 (1608 metric) package with dimensions of 1.6 mm length, 0.8 mm width, and 0.6 mm height, it provides an impedance of 8.5 Ohms at 100 MHz. The component supports a maximum DC current of 8 A and maintains a low maximum DC resistance of 4 mOhms. It operates within a temperature range of -55°C to +125°C and carries AEC-Q200 qualification for automotive reliability.

• EMI suppression in vehicle infotainment systems

Chip Ferrite Bead Procurement Notes

Verify the specific suffix code against official Murata documentation to confirm exact electrical tolerances and material composition. Ensure the ordered variant matches the required AEC-Q200 certification status for automotive integration. Cross-reference the impedance value at 100 MHz with system requirements to validate EMI performance specifications before finalizing procurement orders.

Chip Ferrite Bead Selection Notes

Select this component when designing circuits requiring significant current capacity alongside effective high-frequency noise attenuation. The 8 A rating distinguishes it from lower-current alternatives in the same series. Consider the 0603 package size for board density constraints while ensuring the thermal management capabilities align with the intended operating environment and duty cycle requirements.

Chip Ferrite Bead Part Context

This part belongs to the BLE series of ferrite beads manufactured by Murata Electronics. It is specifically engineered for robust performance in demanding environments, distinguishing itself through its high current tolerance compared to standard signal-line ferrites. The series targets applications where both power integrity and signal cleanliness are critical design parameters.

Chip Ferrite Bead Replacement Considerations

The BLE18PS080BH1D serves as a verified alternative within the same series, offering similar impedance characteristics but with a reduced maximum DC current rating of 5 A and an extended maximum operating temperature of +150°C. Verify that the lower current capacity meets the specific circuit load requirements before substitution.
