Chassis mount resistors are electronic components used to regulate electric current in electronic circuits. They are designed to be fixed to a chassis and use metal conducting elements to create a current path within a circuit. The L100J7K5E is a type of chassis mount resistor that is primarily used in telecommunications systems and power supplies.The L100J7K5E is a high power surface mount resistor with a power rating of 250W at 400V. It is designed to dissipate large currents over short pulses. The L100J7K5E is a ceramic encased resistor that features an epoxy coating and an insulated base to ensure that it does not heat up excessively. The resistor also has a metalized aluminum alkyd coating that provides excellent protection against electrical arc over.The L100J7K5E resistor works by using a structure known as a \'ceramic bed\'. This bed is composed of two sheets of ceramic material with a metallized surface layer on them. The surface layer is composed of a metalized aluminum alkyd. When a current passes through this bed, it causes the metallized surface layer to heat up, and this generates an impedance within the circuit. The impedance generated by the resistor is dependent on the voltage gradient across the resistor, and this determines the amount of current that is allowed to pass through the resistor.The L100J7K5E resistor is used in telecommunications systems, power supplies, and certain products with high voltage requirements, such as MRI machines. It is typically used in large scale production lines because it can handle high current pulses without overheating. The L100J7K5E is also used in DC and AC circuits where a high power resistor is needed for noise reduction or over-voltage protection.The L100J7K5E is one of the most reliable and durable chassis mount resistors on the market. It is designed to withstand high current pulses and temperatures. The epoxy coating and insulated base prevent the resistor from becoming overwhelmed with heat, ensuring that it continues to provide a reliable impedance. The fast response time and durable construction of this resistor make it one of the best choices for resistor applications in which high power and performance are required.In conclusion, the L100J7K5E is a high power surface mount resistor designed for telecommunications systems and power supplies. It works by creating an impedance within a circuit when a current passes through its ceramic bed. The metallized alkyd coating and insulated base protect the resistor from electrical arc over and excessive heat. The reliable performance and durable construction make the L100J7K5E an ideal choice for applications where high power and performance are a must.
