AVX implantable capacitors

AVX has brought out thin film chip capacitors for implantable medical devices.

Delivering extremely tight capacitive tolerances, repeatable performance, low ESR and high Q at high frequencies — including VHF, UHF, and RF bands — AVX’s Accu-P MP Series capacitors are stable with respect to temperature, time, frequency, and voltage variation.

Based on thin film technology and materials, and subjected to on-line process control procedures, in addition to accelerated life, damp, 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, Accu-P MP Series capacitors are for use in medical RF signal and power applications that require high accuracy, such as embedded medical systems and implantable medical devices.

Accu-P MP Series medical grade capacitors are currently available in three standard case sizes (0201, 0402, and 0603), five rated voltages (10V, 16V, 25V, 50V, and 100V), two dielectric temperature coefficients (0±30ppm/°C and 0±60ppm/°C), and with capacitive tolerances spanning ±0.01pF to ±5%. Rated for use in operating temperatures spanning -55°C to +125°C, the series is also available with tin/lead (Sn/Pb) terminations or RoHS compliant and lead-free compatible 100% tin terminations.

Designed for soldering onto flexible or alumina circuit boards, Accu-P MP Series capacitors can withstand the time and temperature profiles used in both wave and reflow soldering methods. Shipped in bulk or on 7” or 13” reels, the components should be handled with plastic-tipped tweezers, vacuum pick-ups, and other pick-and-place machinery. Lead time for the series is nine weeks for production quantities.
