For signal & power applications in applications calling for AEC-Q200, the Accu-P Series SMD capacitors deliver the tightest capacitive tolerances, in addition to exceptionally repeatable performance, extremely high stability, and low ESR and high Q at high frequencies

Qualified to AEC-Q200, AVX’s new automotive grade Accu-P Series capacitors deliver the tightest tolerances of any capacitor available on today’s market (down to ±0.01 pF), in addition to repeatable performance, low ESR and high Q at high frequencies (including VHF, UHF, and RF bands), and extremely high stability with respect to temperature, time, frequency, and voltage variation when compared to ceramic capacitor technologies.


Based on well-established thin film technology and materials, the capacitors are also subjected to a battery of test and quality control procedures in accordance with ISO 9001, CECC, IECQ, and USA MIL — 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.


The capacitors are available in three standard case sizes (0402, 0603, and 0805), six rated voltages (10V, 16V, 25V, 50V, 100V, and 200V), and two dielectric temperature coefficients (0±30 ppm/°C and 0±60 ppm/°C) with capacitance values spanning 0.05 pF to 68 pF, and capacitive tolerances from ±0.01 pF to ±5%. Rated for use in operating temperatures spanning -55°C to +125°C, the ruggedly constructed series also offers four termination compositions.


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.
