Gideon Analytical Laboratories received several T491D475K050AT Kemet tantalum capacitors for electronic failure analysis. A capacitor is a passive two-terminal electronic component that stores electrical energy in an electric field. While some capacitance exists between any two electrical conductors in proximity in a circuit, a capacitor is a component designed to add capacitance to a circuit. The Kemet T491D475K050AT has a capacitance of 4.7 uF, a voltage rating of 50 VDC, and a tolerance of 10%, measures 7.
Gideon Analytical Laboratories received two 1N645 silicon rectifier diodes for failure analysis. One was bad and the other was a quality diode to be used for comparison. A rectifier is an electrical device that converts alternating current(AC), which periodically reverses direction, to direct current(DC), which flows in only one direction. Rectifiers are used inside the power supplies of virtually all electronic equipment. AC/DC power supplies may be broadly divided into linear power supplies ands witched-mode power supplies.
Gideon Analytical Laboratories received several Murata Electronics GCM21BR70J106KE22L Multi-Layered Ceramic Capacitors (MLCCs) for failure analysis. An MLCC consists of a number of individual capacitors stacked together in parallel and contacted via the terminal surfaces. The starting material for all MLCC chips is a mixture of finely ground granules of paraelectric or ferroelectric raw materials, modified by accurately determined additives. The Murata Electronics GCM21BR70J106KE22L has a capacitance of 10 uF, a DC voltage rating of 6.
Gideon Analytical Laboratories received two On Semiconductor SS16 rectifier for failure analysis. The On Semiconductor SS16 Schottky Rectifier features glass-passivated junctions and a high-current capacity. Their applications include low voltage, high-frequency inverters, freewheeling, and polarity protection. Their storage temperature range is between -65 and 150 Degrees Celsius and the operating junction temperature is between -65 and 125 Degrees Celsius. Along with the two failed rectifiers, several good devices were also supplied for comparison.
Gideon Analytical Laboratories received two Sunon Maglev MC35101V2-000U-G99 12V fans which did not operate. Along with the nonoperational fans, two functional fans were also sent to us for comparison. The Sunon Maglev MC35101V2-000U-G99 12V fan is an axial DC fan, with a speed of 7500 RPM and airflow of 6.5 CFM. An axial fan is a type of fan that causes gas to flow through it in an axial direction, parallel to the shaft about which the blades rotate.
Gideon Analytical Laboratories received four Vishay CRCW2512220RJNEG thick film chip resistors to be analyzed. Thick film resistors are the most used resistors in electrical and electronic devices. The resistive material is a special paste with a mixture of a binder, a carrier, and the metal oxides to be deposited. These Vishay CRCW2512220RJNEG resistors thick film chip resistors feature stability at different environmental conditions and 2mm pitch packaging option for 0603 sizes.
Gideon Analytical Laboratories received two LUMEX SSL-LX093UWC/Gc LEDs for failure analysis. A LED (Light Emitting Diode), is a semiconductor light source that emits light when current flows through it. LEDs can be used in many different applications. Electrons in the semiconductor recombine with electron holes, releasing energy in the form of photons. Some of the more creative uses include creating an LED virtual sky, LED bionic contact lenses, and LED wallpaper.
Gideon Analytical Laboratories received six pulse transformer. Three were good, three were failures. Transformers can be thought of as an electrical component rather than an electronic component. A transformer basically is very simple static (or stationary) electro-magnetic passive electrical device that works to convert electrical energy from one value to another. The transformer does this by linking together two or more electrical circuits using a common oscillating magnetic circuit which is produced by the transformer itself.
Gideon Analytical Laboratories received a programmable logic device (PLD) P18586P for failure analysis. A programmable logic device is an electronic component used to build reconfigurable digital circuits. Unlike a logic gate, which has a fixed function, a PLD has an undefined function at the time of manufacture. Before the PLD can be used in a circuit it must be programmed. A PLD is a combination of a logic device and a memory device.
Gideon Analytical Laboratories received two acrylic film capacitors for electronic failure analysis. Six good capacitors were also provided for comparison. A capacitor is a passive two-terminal electrical component that stores potential energy in an electric field. The effect of a capacitor is known as capacitance. While some capacitance exists between any two electrical conductors in proximity in a circuit, a capacitor is a component designed to add capacitance to a circuit.
