X7R - HIGH RELIABILITY - 16Vdc to 10KVdc
NOVACAP manufactures and tests X7R chips
in accordance with MIL-PRF-55681, MIL-PRF-123, MIL-PRF-
49467, or customer SCD. Product is designed for optimum reliability, burned in at elevated voltage and
temperature, and 100% physically and electrically inspected to ascertain conformance to strict perform-
ance criteria. Voltage ratings from 16 VDC to 10,000 VDC are available on standard EIA case sizes.
Applications for High Reliability products include medical implanted devices, aerospace, airborne and var-
ious military applications, and consumer uses requiring safety margins not attainable with conventional
product.
CAPACITANCE & VOLTAGE SELECTION FOR POPULAR CHIP SIZES
3 digit code: two significant digits, followed by number of zeros eg: 183 = 18,000 pF. R denotes decimal, eg. 2R7 = 2.7 pF
