1000B-5001NL

Overview

The iNRCORE 1000B-5001NL is a surface mount audio and signal transformer designed for high-frequency applications. It features a quad configuration with shunt choke functionality, supporting a frequency range of 100 kHz to 100 MHz. The component provides an inductance of 350 µH and maintains a 1:1 turns ratio. It operates within a temperature range of -55°C to +125°C and includes a 1.5 kV insulation voltage rating. The unit utilizes SMD/SMT termination types and is housed in a compact package measuring 17.53 mm in length, 12.19 mm in width, and 5.72 mm in height.

Feature Summary

• Quad channel architecture with integrated shunt choke functionality
• High-frequency operation capability spanning 100 kHz to 100 MHz
• Robust thermal performance suitable for extreme environments up to 125°C

Applications

• Telecommunications signal processing circuits
• Ethernet interface implementations requiring 100Base-TX compatibility
• Audio signal isolation and transformation systems

Procurement Notes

Verify the specific suffix designation during procurement, as variants such as FXNL or XNL may indicate differences in packaging or terminal configuration. Confirm RoHS compliance status directly with the manufacturer or authorized distributors, as regulatory adherence can vary by production batch. Ensure that the selected part number matches the required channel count and inductance specifications for the target circuit design to avoid integration issues.

Selection Notes

Select this component when a quad-channel solution with shunt choke capabilities is required for high-frequency signal integrity. The wide operating temperature range makes it suitable for industrial or automotive environments where thermal stability is critical. Consider the physical dimensions and SMD footprint compatibility with the PCB layout constraints before finalizing the design choice.

Part Context

This component belongs to the 1000B series of audio and signal transformers manufactured by iNRCORE. The series is characterized by its versatility in handling both audio and telecommunication signals across various frequency bands. The 1000B-5001NL specifically addresses applications needing multiple isolated channels within a single compact surface-mount package, distinguishing it from single-channel alternatives in the same product family.

Replacement Considerations

Direct substitutes include the 1000B-5001FXNL and 1000B-5001FXNLT, which share similar electrical characteristics but may differ in reel packaging or terminal plating. Verify pinout compatibility and mechanical dimensions before swapping parts to ensure seamless board integration without redesigning the footprint.
