AVX has released a series of SMD thin film chip capacitors designed to meet performance specifications in automotive signal and power applications. AVX’s automotive grade Accu-P series capacitors feature capacitance values spanning 0.05pF to 68pF, and capacitive tolerances from ±0.01pF to ±5%, in addition to a repeatable performance, low ESR and high Q at high frequencies (including VHF, UHF and RF bands) and high stability with respect to temperature, time, frequency and voltage variation when compared to ceramic capacitor technologies.

Automotive grade Accu-P Series capacitors have two dielectric temperature coefficients (0±30ppm/°C and 0±60ppm/°C). Rated for use in operating temperatures spanning -55°C to 125°C, the AVX automotive grade Accu-P series capacitors feature nickel/solder-coated terminations that provide solderability and leach resistance.

Based on thin film technology and materials, the Automotive Grade Accu-P Series capacitors are also subjected to test and quality control procedures, including on-line process control procedures, accelerated life, dampness and heat testing, and final quality inspections for capacitance, proof voltage, IR and breakdown voltage distribution, temperature coefficient, solderability, and dimensional, mechanical and temperature stability. These are requisites in automotive signal and power applications that require high accuracy, such as: in-vehicle and vehicle-to-vehicle communications systems, vehicle location and alarm systems, GPS, in-cabin wireless LANs and mobile communications including navigation, traffic information and connected security systems.

Designed for soldering onto flexible or alumina circuit boards, automotive grade Accu-P series capacitors can withstand the time and temperature profiles used in both wave and reflow soldering methods.
