T9021

Pulse Transformers Overview

The T9021 is a quad-port surface mount pulse transformer designed for T1/E1 applications. It features a turns ratio of 1:2.42 for both transmitter and receiver channels with a minimum inductance of 600µH. The component measures 28.58mm x 12.32mm x 7.24mm and operates within a temperature range of 0°C to +70°C. It includes IC side protection circuits on each channel to suppress low voltage transients and offers a minimum isolation voltage of 1500 Vrms.

Pulse Transformers Feature Summary

• Integrates four independent transformers in a single low-profile surface mount package
• Includes integrated IC side protection circuitry on each channel to suppress low voltage transients
• Utilizes patented interlock base construction for high reliability
• Compatible with IC grade transfer-molded packages that withstand 235°C IR reflow

Pulse Transformers Applications

• T1 line interface circuits
• E1 line interface circuits
• CEPT standard communication systems
• ISDN-PRI network interfaces

Pulse Transformers Procurement Notes

Verify the specific suffix (e.g., NLT) against the required packaging format such as tape and reel or cut tape. Confirm RoHS compliance status and moisture sensitivity level requirements for your assembly process. Ensure the operating temperature range aligns with your system environment specifications before finalizing procurement orders.

Pulse Transformers Selection Notes

Select this component when designing T1/E1 interfaces requiring integrated transient protection. The quad-port configuration reduces board space compared to discrete solutions. Verify compatibility with target controller chips, such as PMC-Sierra’s Comet series, to ensure signal integrity and proper impedance matching for the 1:2.42 ratio.

Pulse Transformers Part Context

This part belongs to Pulse Electronics' audio and signal transformer category, specifically engineered for digital telecommunication standards. It serves as a critical interface component between line drivers and physical media converters in telecommunications infrastructure equipment.

Pulse Transformers Replacement Considerations

Check for direct substitutes within the same manufacturer's T1/E1 transformer portfolio. Verify pinout compatibility and electrical parameters if considering alternative brands. No specific public substitute part numbers are confirmed in available documentation.
