KEMET X7R Series

KEMET X7R series capacitors with KONNEKT™ technology

KEMET X7R Series

KEMET's X7R with KONNEKT™ technology surface mount capacitors are designed for applications where higher capacitance and voltage are needed without requiring additional board space. KONNEKT high density packaging technology uses an innovative Transient Liquid Phase Sintering (TLPS) material to create a surface mount multichip solution for high density packaging.

KEMET’s X7R dielectric features a +125°C maximum operating temperature and is considered temperature stable. The Electronics Components, Assemblies and Materials Association (EIA) characterises X7R dielectric as a Class II material. Components of this classification are fixed, ceramic dielectric capacitors suited for bypass and decoupling applications or for frequency discriminating circuits where Q and stability of capacitance characteristics are not critical. X7R exhibits a predictable change in capacitance with respect to time and voltage, boasting a minimal change in capacitance with reference to ambient temperature. Capacitance change is limited to ±15% from −55°C to +125°C.

In addition to their use in power supplies, these capacitors can be used in industries related to automotive (hybrid), telecommunications, medical, military, aerospace, semiconductors and test/diagnostic equipment. Automotive Grade devices are also available which meet the demanding Automotive Electronics Council's AEC-Q200 qualification requirements
