PM61300-3

Overview

The PM61300-3 is a surface-mount inverter transformer manufactured by Bourns Inc., designed for Cold Cathode Fluorescent Lamp (CCFL) applications. It features an inductance of 27uH with a tolerance of 10%. The component is specified for use in CCFL inverters operating at 15V. This specific part number is identified as obsolete, indicating it is no longer in active production or distribution.

Feature Summary

• Surface mount construction for automated assembly
• Designed for CCFL inverter circuits
• Fixed inductance specification

Applications

• CCFL backlighting systems
• Display panel illumination inverters

Procurement Notes

This component is officially listed as obsolete by the manufacturer and distributors. Verification of current availability requires checking secondary market sources or authorized surplus dealers. Confirm RoHS compliance status, as some listings indicate non-compliance for this specific suffix. Ensure the replacement part meets the original electrical requirements before integration.

Selection Notes

Due to the obsolete status of the PM61300-3, direct sourcing from primary channels is not possible. Selection should focus on identifying equivalent transformers with matching 27uH inductance and SMD package dimensions. Verify that substitute components support the required 15V operation and fit the existing PCB footprint without modification.

Part Context

The PM61300-3 belongs to the Bourns PM61300 series of SMD CCFL transformers. This series was discontinued due to lack of sales volume and diminishing demand for CCFL technology. The product line has been phased out in favor of newer LED-based solutions, rendering these legacy components unavailable through standard manufacturing pipelines.

Replacement Considerations

Public confirmed substitutes are not explicitly listed in the provided documentation. Users must identify cross-reference parts based on identical inductance (27uH), voltage rating (15V), and physical package constraints.
