Radial Leaded 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.
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.
Radial lead type aluminum electrolytic capacitors are widely used in electronic precision instruments. Various small electronic devices for resonance, coupling, filtering, bypass.
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.

SHDR® Application Notes
Caution For Assembling Capacitors
1. Do not directly touch tetminal by hand.
2. Do not short between terminals with conductor near the capacitor.
3. Do not use conditions for assembling capacitors.
(1). Damp conditions such as water,saltwater spray, or oil spray or fumes.High humidity or humidity condensation situstions.
(2). In an atmosphere filled with toxic gasses(such as hydrogen sulfide, sulfurous acid,nitrous acid, chlorine,ammonia, etc.)
(3). Being exposed to direct sunlight, ozone, ultraviolet ray, or radiation.
(4). Being exposed to acidic or alkaline solutions.
(5). Under severe conditions where vibration and/or mechanical shock exceed the applicable ranges of the specification.
Maintenance Inspection
Please periodically inspect the capacitors that are installed in industrial equipment. Remarkable abnormality such as vent operation, leaking electrolyte etc. Capasitance, dielectric loss tangent,leakage currentand items specked in the specification.
Safe Precautions
1. If you see smoke due to operation of safety vent, turn off the main switch or pull out the plug form the outlet.
2. Do not bring your face near the capacitor when the pressure relief vent operates, because the gasses emitted from that are over 100C. If the gas gets into your eyes, please flush your eyes immediately in pure water. If you breathe the gas,immediately Wash out your mouth and throat with waber. Do not ingest electrolyte.If your skin is exposed to electrolyte, please wash it away using soap and water.
Storage
1. It is recommended to keep capacitors between the ambient temperatures of 5C to 35C and a relative humidity of 75% or below.
2. Confirm that the environment does not have any of the following conditions.
(1). Damp conditions such as water,saltwater spray, or oil spray or fumes.High humidity or humidity condensaUon situations.
(2). In an atmosphere filled with toxic gasses ( such as hydrogen sulfide, sulfurous acid, nitrous acid, chlorine,ammonia, etc.)
(3). Being exposed to direct sunlight, ozone, ultraviolet ray, or radiation
(4). Being exposed to acidic or alkaline solutions
(5). Under, severe conditions where vibration and/or mechanical shock exceed the applicable ranges of the specification
Disposal
1. Make a hole the in the capacitor body or crush Capacitors and incinerata them
2. If indneration is not applicable hand them over to a waste disposal agent and have them buried in landfill
Spedal Notice
When choosing capacitors if dients couldn't find the series or specification in catalogue and data sheet, please contact with our Sales or RD department we are able to base On clients'needs to develop product with specie functions.
