B2013FNLT

Overview

The B2013FNLT is a surface-mount common mode choke manufactured by Pulse Electronics. It features an inductance of 9 mH at 100 kHz and a maximum DC current rating of 100 mA. The component has a DC resistance of 1 Ohm and supports a voltage isolation of 1500 Vrms. Designed for two-line applications, it utilizes a shielded construction to minimize electromagnetic interference. The device operates within a temperature range of -40°C to +125°C and is packaged in a standard SMD form factor suitable for automated assembly processes.

Feature Summary

• Provides effective common mode noise suppression for high-speed data lines
• Features high insulation voltage capability for signal integrity protection
• Utilizes shielded design to reduce external electromagnetic interference

Applications

• ADSL line filtering
• High-speed data interface protection
• Telecommunications equipment signal conditioning

Procurement Notes

Verify the specific datasheet revision and qualification status before integration. Confirm that the 100 mA current rating aligns with the target circuit's operational requirements. Ensure the 1500 Vrms isolation specification meets safety standards for the intended application environment. Cross-reference the package dimensions with the PCB footprint to guarantee mechanical compatibility during assembly.

Selection Notes

Select this component when designing circuits requiring significant common mode attenuation for low-current data lines. The 9 mH inductance value is optimized for ADSL frequency bands. Consider the 1 Ohm DC resistance impact on signal loss. Evaluate the thermal performance at the maximum operating temperature of 125°C to ensure long-term reliability under continuous load conditions.
