PH9185.011NL

Pulse Transformers Overview

The PH9185.011NL is a high isolation power transformer from the PH9185 series, designed for surface mount applications. It features a 750µH inductance with a 1:1 turns ratio and dual primary/dual secondary winding configuration. The component operates at 100kHz and includes an integrated shield to minimize electromagnetic interference. Physical dimensions are 10.00mm x 10.00mm x 12.50mm maximum height. It complies with RoHS3 standards and holds UL/TUV certification for safety isolation requirements.

Pulse Transformers Feature Summary

• High isolation capability suitable for sensitive communication interfaces
• Dual primary and dual secondary winding structure for balanced signal transmission
• Integrated shielding design to reduce electromagnetic interference
• Surface mount package optimized for automated assembly processes

Pulse Transformers Applications

• RS-485 communication interface circuits
• RS-232 communication interface circuits
• Industrial control systems requiring isolated signal transmission
• Building automation network nodes

Pulse Transformers Procurement Notes

Verify that the specific order matches the PH9185.011NL designation rather than the tape-and-reel variant PH9185.011NLT if cut-tape or reel quantity flexibility is required. Confirm UL/TUV certification status is necessary for the target application's regulatory compliance. Check moisture sensitivity level handling procedures during storage and reflow soldering to ensure component integrity.

Pulse Transformers Selection Notes

Select this component when high isolation voltage is required for RS-485 or RS-232 data lines. The 750µH inductance supports standard baud rates in industrial environments. Ensure board space accommodates the 12.50mm maximum height. Consider the PH9185.012NLT if a 1:2 turns ratio is needed instead of the 1:1 configuration provided by this model.

Pulse Transformers Part Context

This part belongs to the PH9185 series of high isolation transformers manufactured by Pulse Electronics. The series is engineered for switch-mode power and communication applications where galvanic isolation is critical. The PH9185.011NL specifically targets serial communication protocols, offering a compact solution compared through-hole alternatives while maintaining robust electrical performance.

Pulse Transformers Replacement Considerations

PH9185.011NLT serves as the functional equivalent with identical electrical characteristics but differs in packaging format (tape and reel vs. cut tape/reel). Verify pin compatibility and mechanical footprint before substitution. No other direct cross-model replacements are documented in public sources.
