BLE32PN300SZ1L

Chip Ferrite Bead Overview

The BLE32PN300SZ1L is a single-line ferrite chip bead manufactured by Murata Electronics, designed for power line noise suppression. It features a 1210 (3225 metric) surface-mount package with dimensions of 3.2 mm length, 2.5 mm width, and a maximum height of 2.20 mm. The component exhibits an impedance of 30 Ohms at 100 MHz with a tolerance of ±10 Ohms. It supports a maximum rated DC current of 10 A and maintains a maximum DC resistance (DCR) of 1.6 mOhms. The device operates within a temperature range of -55°C to +125°C and holds AEC-Q200 qualification.

Chip Ferrite Bead Feature Summary

• Provides effective electromagnetic interference suppression on high-current power lines through high-capacity ferrite material.
• Engineered for automotive reliability with AEC-Q200 qualification and extended operating temperature range.
• Utilizes a compact 1210 surface-mount footprint to facilitate dense circuit board layouts.

Chip Ferrite Bead Applications

• Automotive electronic control unit power distribution networks
• High-current DC-DC converter output filtering
• Power supply input noise attenuation in industrial equipment

Chip Ferrite Bead Procurement Notes

Verify the specific suffix configuration against official Murata documentation to ensure correct impedance and packaging specifications. Confirm that the requested quantity aligns with standard factory pack sizes or cut tape availability. Cross-reference the manufacturer part number with authorized distributor listings to validate authenticity and traceability before finalizing procurement orders.

Chip Ferrite Bead Selection Notes

Select this component when designing circuits requiring significant current handling capability alongside noise filtration. The 10 A rating makes it suitable for main power rails where lower-current beads would saturate. Ensure the PCB layout accommodates the 1210 package dimensions and that the thermal environment remains within the specified -55°C to +125°C operational limits for long-term stability.

Chip Ferrite Bead Part Context

This component belongs to the BLE32PN series of chip power beads from Murata Electronics. The series is characterized by high saturation current capabilities and low DC resistance, making it distinct from standard signal-line ferrite beads. It serves as a specialized solution for managing conducted emissions in power-sensitive applications while maintaining electrical integrity under heavy load conditions.

Chip Ferrite Bead Replacement Considerations

Consult official Murata substitution guides for verified equivalents. Generic cross-references may not match the specific AEC-Q200 qualification or the precise 10 A current handling requirements of this model.
