Non-Magnetic Capacitors: High Q, C0G/NP0, X7R
Components with a copper barrier and a tin finish on top provide a fully non-magnetic component to be used in medical applications where non-magnetic components are required.
MLC capacitors with silver/palladium (Ag/Pd) terminations are essential for medical and other non-magnetic applications, such as MRI equipment, where conventional nickel barrier terminations are unsuitable due to their magnetic properties. RoHS compliance requires lead-free soldering, increasing soldering temperatures and causing solder leaching in Ag/Pd terminations. A solution is using a copper barrier with a tin finish, ensuring a fully non-magnetic component. These capacitors are available with non-magnetic C0G/NP0, High Q, and X7R dielectrics, designed for optimized performance and durability. They serve various applications, including MRI, PIM-sensitive systems, navigation, and semiconductor processing.
