Bourns launches 2nd-gen automotive isolation transformers

These AEC-Q200 compliant, automotive-grade push-pull high voltage isolation transformers offer a high reliability, compact solution that delivers reinforced insulation for working voltages up to 800V and basic insulation for working voltages up to 1,000V. By providing a separate reinforced insulating layer that protects against dangerous voltages, the Model HCT8xxxEAL Series helps designers better meet their safety and reliability goals compared to competitive isolation transformers that are only capable of functional insulation.

The advanced features in this series make these transformers ideal for use in isolation applications in automotive Battery Management Systems (BMS), RS-485, CAN interface, digital input module, and RS-323 isolation designs.

Bourns’ latest high voltage isolation transformers feature 3.3 or 5V input to various output voltages per turn (up to 350mA in various turns ratio configurations). Manufactured in a fully automated line that maximises device quality and reliability, the Model HCT8xxxxxEAL Series is designed with Bourns’ over-moulding technology that uses cost-effective FIW wire to deliver superior efficiency. In addition to the reinforced isolation with 8mm minimum clearance/creepage distance that delivers an elevated level of isolation from high voltage hazards, this series is compliant with IEC 62368-1 and IEC 61558-1 standards. Bourns developed these new transformers for isolation power supplies that employ Texas Instruments Model SN6501 and SN6505 transformer drivers.

Available now, the Bourns HCT8xxxxEAL Series is RoHS* compliant.
