Chassis mount resistors are typically mounted directly on the circuit board and are used to limit current, divide voltages, modify signals, and protect circuits. The TE2500B3R9J is a highly reliable, planary mounting, multi-tap resistors ideal for bridge voltage level applications. This article will discuss the applications and workings of the TE2500B3R9J.

The TE2500B3R9J is ideal for high-volume, high-density applications such as board-level voltage regulation. With a 0.25W peak power dissipation, the resistor can be used for general electronic equipment where low-cost, high accuracy, and reliability are required. The TE2500B3R9J features seven taps that provide a constant resistance of 0.5 ohms to 10 ohms. The planar design and mounting method provide excellent physical stability.

Working Principle

The TE2500B3R9J uses a planar construction with graphite-based resistive material sandwiched between two copper circuit layers. These layers are etched and stamped to form a multitude of resistive circuits. The strips are electrically isolated from each other by cutting out portions of the copper layers. The resistive material is held in place by a layer of epoxy resin between the copper layers. This construction allows the resistor to withstand harsh operating conditions while maintaining its high accuracy.

The resistance of the resistor can be adjusted by cutting away sections of the copper layers to form the desired resistance value. The resistor is mounted onto a circuit board via a threaded hole and a top lug. The resistor is secured to the board with a nut, washer, and a steel rivet that connects the copper layers to the board. This method allows for easy installation and removal of the resistor.

Applications

The TE2500B3R9J is a highly-reliable chassis mount resistor that can be used in a variety of applications, including high-end motor control, SMPS, LED lighting, and spread-spectrum clock generators. The resistor is also ideal for use in DC-DC, AC-DC, and DC-AC power supplies, as it can be used to regulate and control the voltage. The resistor can also be used to divide voltage levels and to scale amplitude signals.

The TE2500B3R9J is also suitable for use in automotive and aerospace applications, where its highly stable design and construction can provide the necessary resistance and voltage control. The resistor can also be used in military and medical devices, where its high accuracy and reliability are necessary for precise operation.

The TE2500B3R9J is a highly reliable and cost-effective resistor that is suitable for a wide range of applications. Its planar construction and mounting method provide excellent stability and reliability, while its wide range of taps make it an ideal choice for board-level voltage regulation, motor control, SMPS, and LED lighting.
