Radial Lead Capacitor

Radial Lead Capacitor

Radial lead capacitor has two leads that protrude from the bottom of the capacitor. In this sense, they are different from the configuration of axial capacitors, which have one lead at each end.

We offer different types of radial leaded capacitors customized ranging from 1000uf25v to 4700uf35v, customizing radial electrolytic capacitors to your requirements for all your applications.

Features:

Radial leaded electrolytic capacitors are high volume, small size, high reliability, long life, high reliability, stable capacity, good resistance to high temperature and humidity, etc.

Application scope:

Radial leaded capacitor is widely used in electronic precision instruments. Various small electronic devices for resonance, coupling, filtering, bypass.

How to distinguish the positive and negative polarity of radial lead capacitors?

Radial electrolytic capacitors are polarized, so it is important for them to have the polarity soldered correctly. If not, they will exhaust (bulge at the top) after a few minutes of operation.

The positive and negative electrolytic capacitors are distinguished: the black block with the logo on top of the capacitor is the negative pole, there are two semicircles on the capacitor position on the PCB, the color painted semicircle corresponding to the pin is the negative pole, also the length of the pin is useful to distinguish the positive and negative polarity.

1、Bolt type electrolytic capacitor positive and negative identification. Bolt type aluminum electrolytic capacitors have clear positive and negative identification on the casing, positive pole is marked with "+" and negative pole is marked with "-". Most of the bolt type capacitors have "+" and "-" marks engraved next to the terminals on the cover.

2、Differentiation of positive and negative electrodes of solder lug aluminum electrolytic capacitors. Solder lug aluminum electrolytic capacitors are also called bullhorn capacitors, currently all manufacturers choose "negative pole marking", that is, the solder pin corresponding to the casing "-" mark is the negative pole. Most of them adopt "embossing" to identify the negative pole, and some electrolytic capacitor manufacturers directly print "+" and "-" on the rivet. logo.

3、Lead structure electrolytic capacitor positive and negative identification method. The lead structure electrolytic capacitor also adopts "negative pole identification", that is, the lead corresponding to the "-" mark of the casing is negative pole. There is also the identification by the length of the lead, the long lead is the positive pole, the short lead is the negative pole.
