Balun Procurement Notes

This component is officially listed as obsolete by Murata Electronics. Procurement should focus on verifying stock availability through authorized distributors or secondary markets. Buyers must confirm the specific lot date and authenticity due to the discontinued status. Integration into new designs is discouraged; existing systems should plan for migration strategies. Verify RoHS3 compliance documentation if required for regulatory adherence in final assemblies.

Balun Selection Notes

Engineers selecting this part should note its obsolete lifecycle status, which impacts long-term supply chain stability. The 0805 footprint and specific impedance transformation from 50 Ω to 200 Ω are critical design constraints. Alternative components with similar frequency ranges and package sizes should be evaluated for future-proofing. Ensure that the PCB layout accommodates the specific RF requirements of hybrid baluns to maintain signal integrity.

Balun Part Context

The LDB21924M20C-001 belongs to Murata's portfolio of passive components focused on signal conditioning. As a balun, it serves to interface balanced differential signals with single-ended lines in RF systems. This specific model represents a legacy solution within the broader category of multi-layer hybrid baluns, previously utilized in various wireless communication hardware before being phased out.

Balun Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Due to the obsolete status, engineers must identify equivalent components based on electrical specifications such as frequency range, impedance ratio, and package size. Consultation with Murata technical support or distributor engineering teams is recommended to find suitable cross-references.
