Overview
The PEMI2STD/CM,115 is a surface-mount RC Pi-filter EMI filter circuit manufactured by NXP USA Inc. It integrates passive filtering components with electrostatic discharge (ESD) protection diodes to safeguard downstream electronics. The device features two channels with a resistance of 20 Ohms per channel and a total capacitance of 16 picofarads. Designed for high-frequency noise suppression, it operates within a temperature range of -40°C to +85°C and is housed in an SOT-665 package.
Feature Summary
- Integrates RC Pi-filter topology for effective electromagnetic interference attenuation
- Includes built-in ESD protection diodes to shield sensitive downstream components
- Compact surface-mount design suitable for space-constrained mobile applications
Applications
- Data lines for mobile devices
- Portable consumer electronics
- High-speed digital signal interfaces
Procurement Notes
Verify the specific suffix CM against the official NXP datasheet to confirm pinout and electrical characteristics match the design requirements. Ensure the component status is active or available through authorized distributors, as lifecycle changes may affect long-term supply. Cross-reference the SOT-665 package dimensions with PCB footprint libraries to guarantee mechanical compatibility during assembly.
Selection Notes
Select this component when low capacitance values around 16pF are required to minimize signal distortion on high-speed data lines while providing necessary ESD robustness. The 20-ohm resistance offers a balance between filtering performance and signal integrity. Consider the SOT-665 package size relative to available board real estate and thermal management needs for the target application environment.
Part Context
This part belongs to the PEMI2STD family of EMI filter circuits from NXP Semiconductors. These devices are engineered to meet stringent EMC standards in portable electronics. The standard designation indicates a dual-channel configuration with integrated protection, distinguishing it from single-channel variants or those with different resistance/capacitance ratios within the same product line.
Replacement Considerations
Check for direct substitutes within the PEMI2STD series that share the SOT-665 package but differ in R/C values, such as PEMI2STD/RP,115. Verify functional equivalence regarding ESD protection levels and insertion loss characteristics before substituting.
