Also, some of the miniature capacitor datasheets don't list the Impedance or ESR , and only Impedance ratio is listed. Adding Filter Capacitor at power rails of LM35: The fluctuation of temperature output might be the noise available in the power supply so it's better to use an electrolytic capacitor at the power supply i.e. Vl380 3528. The information can be used for identifying and selecting capacitors correctly for a given circuit application. The 35 volt part has an 8 mm diameter, while the 63 volt part is 10 mm. Key features follow, with a list of the most popular applications and available safety agency approvals. 1pF = 10 F = 0,000000000001 F nanoFarads ( nF) is the most common unit, and standard polyester capacitors usually fall within this range. Ceramic capacitors should have a voltage derating factor of 0.60 [110C max]. The three-digit capacitance code works as follows: If the third digit is 0 through 6, add that many zeroes to the end of the number. For codes S, X, and Z, the actual capacitance may be as much as 20% below the stated value or as much as 50%, 40%, or 80% over the stated value. 47 * 10000 = 470000 pF = 470 nF = 0.47 uF with the J meaning a 5% tolerance.
