Silicon diodes act as one-way valves for electrical current, allowing it to flow in only one direction. Like any electronic component,

diodes can fail from excessive voltage or current. Fortunately, diodes are simple to test, needing only a good multimeter to check them.

If you set the multimeter to read resistance and put the probes across the diode, you should read a low resistance one way and high resistance

with the probes reversed. A shorted diode will read low resistance both ways, and a blown diode will read high resistance both ways.

Instructions

1.Turn off the power to your circuit or equipment. Let the equipment sit for at least 30 minutes before removing the case or cover to allow the power supply to discharge。

2.Locate the diodes you want to test. They are typically small, two-lead parts with a stripe on the body to indicate the diode's cathode side.

3.Turn the multimeter on and turn the function knob so it points to the resistance setting. Hold the plastic body of the probes and are not touching the metal tips.

Touch the tip of the positive probe to one side of the diode and the negative probe to the other side. Read the resistance measurement and write it down.

Reverse the probes so they're touching the opposite sides of the diode. Write down the resistance you read . The higher resistance should be at least 10

times greater than the lower one. If it's less than five, the diode is very likely bad.

A tantalum capacitor is a type of capacitor with parts made out of the metal tantalum. Because they offer several advantages over older and more standard aluminum capacitors, tantalum capacitors are becoming increasingly popular and are often included in newer circuit designs.

IdentificationA capacitor is an electronic component made out of two conductive plates separated by an insulating material. It is used to store energy.

Tantalum

Tantalum is a rare, hard, heavy, blue-grey metal. It is highly resistant to corrosion and is mostly chemical inert, making it a durable

metal for electronic components. Tantalum capacitors are made from a small amount of mostly pure tantalum powder.

Uses

Tantalum capacitors are used in situations where the capacitor must hold power for a longer period of time.

They are also used with power supplies and in environments that operate at high temperature.

Durability

Because of the way tantalum capacitors are constructed and the natural resistance to corrosion of tantalum,

tantalum capacitors are exceptionally durable. They do not have any parts that wear out with use.

Polarity

One disadvantage to tantalum capacitors is that they are polar devices. They can only operate with power

flowing through them in one direction, unlike some other types of capacitors.

Finding a Bridge Rectifier? How to find the best Bridge Rectifier? Do nothing before you visit our site! We kingtronics is Specialty in design,manufacture of bridge rectifier! We are your best choice.

The bridge rectifier is the most commonly used full wave rectifier circuit for several reasons, one advantage of a bridge rectifier over a conventional full-wave rectifier is that with a given transformer the bridge rectifier produces a voltage output that is nearly twice that of the conventional full-wave circuit.

(1) It does not require the use of center-tapped transformer, and therefore can be coupled directly to the ac power line, if desired.
(2)Using a transformer with the same secondary voltage produces a peak output voltage that is nearly double the voltage of the full wave center-tapped rectifier. This results in the higher dc voltage from the supply.

Kingtronics have UL certification for bridge rectifier, pls see picture of our products, we are glad to get your inquiries!
