BMB1J0070BN3JIT

Chip Ferrite Bead Overview

The BMB1J0070BN3JIT is a single-line ferrite bead from the BMB-B series, manufactured by TE Connectivity Passive Product. It features a 0603 (1608 metric) surface-mount package with dimensions of 1.60mm length and 0.80mm width. The component provides an impedance of 70 Ohms at 100 MHz and has a maximum DC resistance of 500 milliohms. It supports a rated current of 200mA and operates within a temperature range of -55°C to +125°C. The part is RoHS compliant and classified as obsolete.

Chip Ferrite Bead Feature Summary

• Provides effective electromagnetic interference suppression through high-impedance characteristics at target frequencies
• Utilizes a compact 0603 surface-mount footprint for space-constrained circuit board layouts
• Designed for noise filtering in high-frequency signal lines with stable thermal performance

Chip Ferrite Bead Applications

• EMI suppression in portable electronic devices
• Noise filtering for high-speed digital signal lines
• Power line decoupling in compact consumer electronics

Chip Ferrite Bead Procurement Notes

This component is officially listed as obsolete and no longer manufactured by TE Connectivity. Verification of availability should focus on surplus distributors or secondary market sources rather than direct manufacturer allocation. Buyers must confirm the authenticity and storage history of existing stock due to the discontinued status. Compliance documentation such as RoHS statements remains available for reference but does not indicate current production capability.

Chip Ferrite Bead Selection Notes

Engineers requiring this specific impedance value should evaluate alternative ferrite beads from other manufacturers that offer equivalent electrical characteristics in compatible packages. The discontinuation necessitates reviewing pin-compatible substitutes to ensure supply chain stability for new designs. Existing inventory may be suitable for maintenance repairs but is not recommended for long-term production projects without verified substitution strategies.

Chip Ferrite Bead Part Context

The BMB1J0070BN3JIT belongs to the BMB-B series of chip ferrite beads, which are designed for general-purpose EMI suppression. This series is characterized by its ability to absorb high-frequency noise energy and dissipate it as heat. The component serves as a passive filter element in circuits where signal integrity is critical and electromagnetic compatibility standards must be met.

Chip Ferrite Bead Replacement Considerations

Publicly confirmed substitute part numbers include BLM18KG700TN1D from Murata Electronics. Engineers should verify that the substitute matches the required 70 Ohm impedance at 100 MHz and fits the 0603 package constraints.
