S22230

Overview

The S22230 is a specialty isolation transformer manufactured by Newava Technology Inc., designed specifically for use with Maxim Integrated MAX250 and MAX251 transceiver ICs. This component provides digital and audio signal isolation with a 1:1 turns ratio. It features an inductance of greater than 2.0 mH measured at 10 kHz and 0.1 Vrms. The device exhibits low DC resistance, with nominal values of 0.8 mΩ for pins 1-3 and 1.0 mΩ for pins 4-6. It is supplied in tape and reel or cut tape packaging and is RoHS compliant.

Feature Summary

• Provides galvanic isolation for digital and audio signals
• Optimized compatibility with Maxim MAX250/MAX251 transceivers
• High inductance ensures effective signal coupling at operating frequencies

Applications

• Isolation interfaces for MAX250 transceiver circuits
• Isolation interfaces for MAX251 transceiver circuits
• Digital signal transmission in isolated communication systems

Procurement Notes

Verify the specific package variant (Tape & Reel vs. Cut Tape) required for your assembly process when ordering. Confirm that the application environment supports the specified operating temperature range and voltage levels. Ensure compatibility with the target Maxim transceiver models before finalizing procurement to avoid integration issues.

Selection Notes

Select this component only if designing around Maxim MAX250 or MAX251 devices requiring isolated signal paths. Consider the physical dimensions and mounting requirements relative to the PCB layout. Evaluate whether the standard 1:1 isolation ratio meets the system's electrical isolation needs without additional buffering.

Part Context

Newava Technology Inc. specializes in cost-effective transformers for power supply, avionics, military, medical, and test equipment applications. The S22230 belongs to their specialty transformer lineup, focusing on precise isolation solutions for integrated circuit interfacing rather than general-purpose power transformation.

Replacement Considerations

No public confirmed substitute part numbers are available for the S22230. Due to its specific design for Maxim MAX250/251 transceivers, alternative components must be carefully evaluated for pinout compatibility, inductance characteristics, and isolation ratings.
