Procurement Notes

Verify the specific datasheet version and RoHS compliance status directly with Knowles Syfer or authorized distributors before procurement. Confirm that the 1812 footprint and pin configuration match the target PCB layout. Ensure the 500V DC and 10A ratings align with the system's electrical requirements. Check for any recent product change notifications or discontinuation notices associated with this part number.

Selection Notes

Select this component when a compact surface-mount solution is required for EMI suppression in high-voltage applications. The Pi filter structure provides superior attenuation compared to single-capacitor solutions. Ensure the operating environment stays within the specified -55°C to +125°C range. Verify that the 10 nF capacitance value meets the circuit's filtering frequency requirements without causing excessive inrush current issues.

Part Context

This component belongs to the Knowles Syfer SBSG series of EMI filter circuits. These devices are designed as surface-mount alternatives to traditional feed-through capacitors, offering improved integration density. The series combines capacitor functionality with filter network structures to provide comprehensive noise reduction in a small form factor suitable for modern PCB designs.
