Capacitor Tolerances

"E.I.A. TEMPERATURE COEFFICIENTS
Note: Does not apply to temperature compensating types such as NPO, COG, N150, N750, SL, etc.

1st Letter = Low end operating temperature
X= -55�C (-67�F); Y= -30�C (-22�F); Z= 10�C ( 50�F)

2nd Digit = High end operating temperature
2= 45�C ( 113�F); 4= 65�C ( 149�F); 5= 85�C ( 185�F)
6= 105�C ( 221�F); 7= 125�C ( 257�F)

3rd Letter = Maximum Capacitance change
D= �3.3%; E= �4.7%; F= �7.5%; P= �10%; R= �15%; S= �22%
T= 22 to -33%; U= 22 to -56%; V= 22 to -82%

Examples:
Z5U: Operating Temperature 10�C to 85�C. Max. Capacitance Change - 22% to -56%.
X7R: Operating Temperature -55�C to 125�C. Max. Capacitance Change - �15%"
