PET-HT DIELECTRIC – CB Series
GENERAL DESCRIPTION
Film chip
capacitor specification using a naked and stacked construction withmetallized High Temperature PET (polyethylene terephtalate).
ADVANTAGES
• Use of high temperature dielectric films makes thesecapacitors suitable for IR or vapor phase reflow processes.
This chip is built without specific encapsulation.• The intrinsic elasticity of the dielectric film allows anexcellent compatibility of the capacitor with all types of
material for printed circuit boards.• The self-healing property of film technology results to asafety open failure mode and better overall reliability.• Excellent thermal shock resistance.
• Low dissipation factor ESR & ESL.
• No piezoelectric effect.
• Available in tape and reel suitable for automatic placement.
• Non-polar construction.
APPLICATIONS
General purpose function in low voltage applications whereminiaturization and SMD is required. Typical applications
would be:• Automotive (Airbag, Fuel injection calculator...)
• Telecom (Public switching systems,
industrial modems, telephoneset, cordless, mobile)• Industrial (SMPS, Power convertor module...)
