14 x7r dielectric general specifications x7r formulations are called ?emperature stable?ceramics and fall into eia class ii materials. x7r is the most popular of these intermediate dielectric constant materials. its tem- perature variation of capacitance is within ?5% from -55? to +125?. this capacitance change is non-linear. capacitance for x7r varies under the influence of electrical operating conditions such as voltage and frequency. x7r dielectric chip usage covers the broad spectrum of industrial applications where known changes in capaci- tance due to applied voltages are acceptable. part number (see page 2 for complete part number explanation) % cap change 10 -60 -40 -20 0 20 40 60 80 100 120 140 temperature c x7r dielectric typical temperature coefficient 5 0 -5 -10 -15 -20 -25 % capacitance +10 +20 +30 0 -10 -20 -30 1khz 10 khz 100 khz 1 mhz 10 mhz frequency capacitance vs. frequency insulation resistance (ohm-farads) 1,000 10,000 100 0 0 20 120 40 60 80 temperature c insulation resistance vs temperature 100 impedance, 10 100 1000 frequency, mhz variation of impedance with cap value impedance vs. frequency 1,000 pf vs. 10,000 pf - x7r 0805 0.10 0.01 1.00 1,000 pf 10,000 pf 10.00 impedance, 110 100 1,000 frequency, mhz variation of impedance with chip size impedance vs. frequency 100,000 pf - x7r 0.1 .01 1.0 1206 0805 10 1210 impedance, 110 100 1,000 frequency, mhz variation of impedance with chip size impedance vs. frequency 10,000 pf - x7r 0.1 .01 1.0 1206 0805 10 1210 0805 size (l" x w") 5 voltage 4v = 4 6.3v = 6 10v = z 16v = y 25v = 3 50v = 5 100v = 1 200v = 2 500v = 7 c dielectric x7r = c 103 capacitance code (in pf) 2 sig. digits + number of zeros m capacitance tolerance j = 5% k = ?0% m = 20% 2 packaging 2 = 7" reel 4 = 13" reel 7 = bulk cass. 9 = bulk contact factory for multiples a special code a = std. product t terminations t = plated ni and sn 7 = gold plated* z= flexiterm ** a failure rate a = not applicable *optional termination **see flexiterm x7r section note: contact factory for availability of termination and tolerance options for specific part numbers. contact factory for non-specified capacitance values.
