Procurement Notes
Verify the complete part number including suffixes against official Knowles Syfer documentation to ensure correct dielectric type, tolerance, and termination finish. Confirm RoHS compliance status and lead-free specifications if required by your manufacturing standards. Cross-reference with authorized distributors to validate authenticity and supply chain integrity before procurement.
Selection Notes
Select this component when a 1206 footprint is constrained and a 100V rating is necessary. Ensure the X7R temperature coefficient meets the thermal requirements of the specific application environment. Verify that the 3900pF capacitance value aligns with the circuit design needs for filtering or coupling functions without causing impedance mismatches.
Part Context
This part belongs to the Knowles Syfer general-purpose MLCC series. These capacitors are engineered for high reliability in commercial and industrial electronics. The 1206 case size offers a balance between capacitance density and physical space constraints, making it a common choice for modern printed circuit board designs.
Replacement Considerations
Consult official substitution guides for equivalent parts from Knowles Syfer or other manufacturers. Ensure replacement components match the 1206 case size, 100V rating, 3900pF capacitance, and X7R dielectric type. Verify compatibility with existing soldering profiles and PCB layout constraints.
