Let s examine some typical capacitor markings.
Ceramic capacitor positive side.
Make sure you pay close attention to the capacitor positive side and negative side such that you don t damage it or the rest of the circuit.
If there is no or you can orient the capacitor either way.
Many larger capacitors like electrolytic capacitors disc ceramics and many film capacitors are large enough to have their markings printed.
A ceramic capacitor is a fixed value capacitor where the ceramic material acts as the dielectric it is constructed of two or more alternating layers of ceramic and a metal layer acting as the electrodes the composition of the ceramic material defines the electrical behavior and therefore applications.
Some but not all capacitors have a positive and negative lead.
Some capacitors use a colored bar or a ring shaped depression to show polarity.
Below are 10µf left and a 1mf electrolytic capacitors each of which has a dash symbol to mark the negative leg as well as a longer positive leg.
There is no polarity in a ceramic capacitor the ceramic capacitor usually uses 3 digits to represent its value like 102 103 101 for indicating its value and.
Smd capacitor one of the derivatives of smt surface mount technology having small and easy to place components which enhances the manufacturing speed.
Use safety precautions when working with capacitors.
Ceramic capacitors are also called disc capacitors a code of 3 digit is generally printed on the body of this type of capacitors to tell their capacitance in pico farads.
Ceramic tantalum electrolytic capacitors are few of the available options when it comes to smd capacitor.
When new a further polarity making may be used because it may be seen that the positive lead is longer than the negative one.
If so the polarization marking indicates the negative side and generally takes the form of a lightly colored stripe.
How close to the given capacitance the capacitor can be expected to stay.
Smd capacitors most extensively used for capacitor requirements on the pcb which are perfect for large scale manufacturing.
Applying a negative voltage for an extended period to an electrolytic capacitor results in a briefly exciting but catastrophic failure.
Leaded tantalum capacitor markings markings for different types of capacitor.
