B82799S333N1

Overview

The B82799S333N1 is a surface-mount common mode choke manufactured by EPCOS (TDK Electronics). It features a ring core design with two lines, providing an inductance of 33 µH. The component supports a maximum current of 200 mA and has a typical DC resistance of 200 mOhm. It operates within a temperature range of -55°C to 150°C and is housed in a horizontal package with four L-leads. This part is AEC-Q200 qualified for automotive applications.

Feature Summary

• AEC-Q200 qualified for automotive reliability standards
• Ring core construction for effective common mode noise suppression
• Surface mount design for automated assembly integration

Applications

• Automotive data line filtering
• Signal line protection in vehicle electronics
• Common mode interference suppression in compact modules

Procurement Notes

Verify the specific suffix N1 against official TDK documentation to confirm exact tolerance and packaging specifications. Ensure compatibility with AEC-Q200 requirements if used in automotive contexts. Cross-reference datasheet revision dates to avoid obsolete stock. Confirm lead form and mounting orientation match PCB layout constraints before ordering.

Selection Notes

Select this component when high-temperature stability up to 150°C is required for signal integrity. The 33 µH inductance suits moderate frequency noise attenuation. Verify that the 200 mA current rating meets circuit load demands without saturation. Consider the horizontal footprint dimensions for space-constrained automotive board designs.
