The PEMI2STD/WE,115 is a second-order low-pass RC Pi-filter EMI filter with integrated ESD protection. It features two channels with a resistance of 100 ohms per channel and a total capacitance of 18.5 pF. The device provides an attenuation value of 25dB at frequencies between 800MHz and 3GHz. It operates within a temperature range of -40°C to 85°C and utilizes a surface-mount SOT-665 package.
Verify the specific suffix WE against the manufacturer's current product status documentation. This part number is listed as scheduled for obsolescence by the manufacturer. Confirm availability through authorized distributors or secondary market suppliers like Rochester Electronics, as standard production may have ceased. Ensure the datasheet version matches the required specifications before finalizing procurement orders.
Select this component when designing circuits requiring combined EMI filtering and ESD protection in a compact form factor. The 100-ohm resistance and 18.5pF capacitance values are optimized for high-speed data lines. Consider the SOT-665 package dimensions for PCB layout constraints. Verify that the operating temperature range meets the environmental requirements of the target application.
This component belongs to the PEMIxQFN and PEMI2STD families from Nexperia/NXP. These series offer integrated passive filter networks with varying channel counts (1, 2, 4, 6, 8) and ESD protection levels. The PEMI2STD/WE,115 specifically represents a 2-channel variant within this broader portfolio of signal conditioning components.
PEMI2STD/RP,115 is a documented alternative within the same family offering similar filtering characteristics.
