PEMI2STD/HE,115

Overview

The PEMI2STD/HE,115 is a second-order RC Pi-network EMI filter manufactured by Nexperia USA Inc. It integrates resistors and capacitors within a single surface-mount package to suppress electromagnetic interference on data lines. The component features a resistance value of 45 Ohms and a total capacitance of 8.5 picofarads. It is housed in the SOT-665 package, designed for compact circuit board layouts.

Feature Summary

• Integrates a complete second-order RC Pi-filter topology into a single compact component
• Provides effective attenuation of electromagnetic interference (EMI) and radio frequency interference (RFI)
• Designed specifically for signal integrity preservation on high-speed data lines

Applications

• Data line filtering in mobile devices
• High-speed interface protection in consumer electronics
• Signal conditioning for communication ports

Procurement Notes

Verify current manufacturing status as the part may be obsolete or restricted. Confirm exact package dimensions against the official datasheet before finalizing layout. Ensure compatibility with automated pick-and-place equipment regarding the SOT-665 footprint. Check for alternative sources if supply chain continuity is required.

Selection Notes

Select this component when space constraints prevent discrete R-C network implementation. The integrated design simplifies bill of materials and assembly processes. Verify that the 45 Ohm resistance and 8.5 pF capacitance values align with the target impedance and bandwidth requirements of the specific application circuit.

Part Context

This component belongs to Nexperia's portfolio of passive integrated circuits designed for signal integrity management. It addresses the growing need for compact EMI suppression solutions in portable electronics where board real estate is limited. The integration reduces parasitic effects associated with discrete component placement.
