Product Description
Product Overview
Johanson Technology's Multi-Layer High-Q Capacitors are engineered for high-performance applications, including High-Q and microwave circuits. The S-Series offers ultra-high Q performance with NP0 temperature characteristics, while the L-Series provides mid-high Q performance, also with NP0 characteristics. The E-Series delivers excellent high-Q performance across HF to Microwave frequencies, suitable for high voltage and high current applications. All unleaded parts are RoHS compliant, and automotive versions (AEC-Q200) are available upon request for select series.
