Procurement Notes

This product is listed as obsolete and is no longer manufactured by Bourns Inc. Procurement should focus on verifying availability through authorized distributors or secondary market channels. Designers must confirm compatibility with existing inventory and consider long-term supply chain risks associated with discontinued components when integrating this transformer into new or maintenance projects.

Selection Notes

Selection of this transformer requires strict adherence to the electrical specifications defined by the ST VIPER controller family it supports. Engineers must verify pinout compatibility, winding ratios, and core material suitability for the intended frequency range. Due to its obsolete status, alternative solutions from current product lines may offer improved availability and updated performance characteristics for modern design implementations.

Part Context

Bourns Inc. manufactures a broad portfolio of passive components, including resistors, potentiometers, and transformers. The 08378 falls under the specialty transformers category, distinct from their more widely known resistor and protection products. This specific item represents a targeted solution for legacy or specialized power management applications involving VIPER technology.

Replacement Considerations

As the 08378 is obsolete, direct substitutes are not officially confirmed in public documentation. Designers should consult STMicroelectronics application notes for recommended transformer specifications for VIPER ICs and evaluate current Bourns specialty transformers that match those electrical parameters.
