Radial Leaded Capacitor

Radial Leaded 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 lead type aluminum electrolytic capacitors are 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 type capacitor?

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

■ Equipment operation

a) Do not touch the capacitor directly with your hands.

b) Do not short-circuit the terminals of the capacitor by touching it

with any conductive object. Also, do not spill conductive liquids such as

 Acid or alkaline solutions on capacitors.

c) Do not use capacitors where they will be subject to ex-

 Have the following materials ready:

· Oil, water, salt water or damp places.

· Direct sunlight.

· Toxic gases such as hydrogen sulfide, sulfurous acid, nitrous acid, etc.

 Chlorine or its compounds and ammonium.

· Ozone, UV light or radiation.

· Severe vibration or mechanical shock conditions beyond the limit presc-

 Ribbed in catalog or product specification.

■ Maintenance inspection

a) Periodic inspection of capacitors already used in industry

 application. Before checking, please turn off the power and check carefully

 Discharge the electricity in the capacitor. Verify polarity when measuring

 Measure the capacitor with a volt-ohmmeter. Also, do not apply any mechanical-

 anical stress to the terminals of the capacitor.

b) The following items should be checked during periodic inspection.

· Severely damaged appearance: exhaust gas and electrolyte leakage.

Electrical characteristics: leakage current, capacitance, tanδ, etc.

 Characteristics specified in a catalog or product specification. us

 If the part is out of specification, it is recommended to replace the capacitor.

■ When exhausting

a) If non-solid aluminum electrolytic capacitors vent gas when venting,

 emits odor or smoke, or burns in the event of a short circuit

 fail. Immediately turn off or unplug the device from the mains power supply.

b) When venting, a non-solid aluminum electrolytic capacitor fuses

 Gases with temperatures over 100°C. (Solid aluminum electrolytic

capacitors release decomposition gases or combustion gases, while

The outer resin shell is burning. ) Do not expose your face near the vents

capacitor.

If your eyes inadvertently come into contact with the expelled gas or

you inhale it, immediately flush your open eyes with plenty of water

Use water and mouthwash separately. If the electrolyte is on the skin,

 Wash the electrolyte from the skin with soap and plenty of water.

Do not lick the electrolyte of non-solid aluminum electrolytic capacitors.

■ Storage

We recommend the following storage conditions.

a) Do not store capacitors in high temperature or high humidity environments. shop

 capacitors at room temperature of 5 to 35°C and relative to

 Humidity is 75% or less.

b) Store capacitors in a place free of water, oil or salt water.

c) Store capacitors in places free from toxic gases (hydrogen sulfide,

 Sulfurous acid, chlorine, ammonium, etc.)

d) Store capacitors in a place free from ozone, UV light or

 radiation.

e) Keep the capacitors in their original packaging.

■ Disposal

 Consult your local industrial waste disposal specialist
