76250ENC

Overview

The 76250ENC is a through-hole encapsulated converter transformer designed for industrial and medical applications. It provides isolated RS-232 interfaces when used with Maxim chipsets. The component features EN60950 approval, ensuring compliance with safety standards for information technology equipment. It operates within a temperature range of -40°C to +85°C and utilizes a DIP package configuration suitable for robust board mounting in demanding environments.

Feature Summary

• Provides galvanic isolation for RS-232 communication interfaces
• Encapsulated construction for enhanced durability in industrial settings
• Certified to EN60950 safety standards for IT equipment

Applications

• Isolated serial communication links in industrial automation systems
• Medical device data transmission requiring certified isolation
• Ruggedized control panels operating in extreme temperatures

Procurement Notes

Verify the specific revision level and packaging format against current distributor listings, as legacy components may have updated supply chain statuses. Confirm that the target application strictly adheres to the EN60950 standard scope. Ensure compatibility with the intended Maxim chipset variant before finalizing procurement orders to avoid integration issues.

Selection Notes

Select this component when a through-hole solution is required for high-reliability RS-232 isolation. The encapsulated design offers superior protection compared to non-encapsulated variants. Consider thermal constraints and mechanical space requirements for the DIP footprint during PCB layout planning to ensure proper fit within the enclosure.

Part Context

This transformer belongs to the MAX250 series family, specifically engineered for use with Maxim Integrated's MAX250 and MAX251 transceiver chips. It serves as a critical passive component for establishing secure, isolated serial connections in systems where ground potential differences must be managed safely.

Replacement Considerations

Direct substitutes are not explicitly documented in public sources. Evaluate other 76250 series transformers only if electrical parameters and pinout configurations match exactly. Consult Murata Power Solutions directly for official obsolescence management or approved alternative part numbers.
