New SMD thin film chip capacitors from AVX are especially designed for automotive signal and power applications that require extremely 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.
Qualified to AEC-Q200, the ACCU-P series is said to offer very low capacitance values (0.05 pF) and ultra tight capacitance tolerances (±0.01 pF). The series also offers remarkably 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.
The new capacitors are also subjected to a litany 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. Thses features make the components ideal for automotive applications stated above.
“Designed to exhibit ideal performance characteristics in high frequency signal and power applications, Accu-P Series capacitors virtually eliminate the variances in dielectric quality, electrode conductivity, and physical size that are inherent to ceramic capacitor technologies,” said Larry Eisenberger, principal technical marketing engineer, AVX.
“Named for the extreme accuracy they deliver in even demanding applications, Automotive Grade Accu-P Series SMD thin film chip capacitors feature high-purity electrodes for very low and repeatable ESR; high-purity, low-K dielectric for a high breakdown field, high IR, and low losses to frequencies above 40GHz; and very tight dimensional control for uniform unit-to-unit inductance.”
The capacitors are currently 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±30ppm/°C and 0±60ppm/°C) with capacitance values spanning 0.05pF to 68pF, and capacitive tolerances from ±0.01pF to ±5%.
Operating temperatures are specified from -55°C to +125°C. The rugged construction also offers four termination compositions, including RoHS compliant and lead-free compatible options, and nickel/solder-coated terminations that provide excellent solderability and leach resistance.
Designed for soldering onto flexible or alumina circuit boards, the capacitors can withstand the time and temperature profiles used in both wave and reflow soldering methods. Shipped on 7” or 13” reels, the components should be handled with plastic-tipped tweezers, vacuum pick-ups, or other pick-and-place machinery. Lead-time for the series is currently 10 weeks.
