Ceramic Capacitor Positive Side

If there is no or you can orient the capacitor either way.

Ceramic capacitor positive side.

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. Smd capacitor one of the derivatives of smt surface mount technology having small and easy to place components which enhances the manufacturing speed. 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.

Some but not all capacitors have a positive and negative lead. Many larger capacitors like electrolytic capacitors disc ceramics and many film capacitors are large enough to have their markings printed. Leaded tantalum capacitor markings markings for different types of capacitor. 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.

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. Make sure to connect the capacitor s end to the positive side of the circuit or the capacitor could eventually cause a short or even explode. Smd capacitors most extensively used for capacitor requirements on the pcb which are perfect for large scale manufacturing. Some capacitors use a colored bar or a ring shaped depression to show polarity.

Applying a negative voltage for an extended period to an electrolytic capacitor results in a briefly exciting but catastrophic failure. Use safety precautions when working with capacitors. 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. Let s examine some typical capacitor markings.

You can determine an electrolytic capacitor polarity by measuring its voltage drop and capacitance in an electric circuit. The first two digits represent the value of the capacitor and the third digit represents the number of zeros to be added.
