Through Hole Resistors

Through hole resistors are resistors that are mounted with leads which pass through and are soldered on the opposite side. Through hole resistors are commonly used in military applications where vibration and shock are an issue, as the leads provide excellent holding power for the device. Some through hole resistors are also used in extreme temperature applications where the devices need to be mounted to a heat sink. The most commonly used through hole resistor is the MP9100-2.50-1% resistor.

Application Field

The MP9100-2.50-1% resistor is ideally suited for precision instrumentation, automotive, aerospace, consumer electronics, medical and telecommunications markets. It is one of the most popular through hole resistors because of its high reliability, long operational life and power handling capability. The resistor is rated up to 50 V and 1/2 Watt maximum power dissipation, making it perfect for high power applications.

Working Principle

The MP9100-2.50-1% resistor is an axial lead resistor with a lead length of 2 to 4 mm (0.08 to 0.16 in). It has an operating temperature range of -65°C to +150°C and a resistance tolerance of 1%. The resistance is determined by a three digit coding format. The first two digits are the first two digits of the resistance value and the third digit is the number of zeroes to follow. For example, the code MP9100-2.50-1% reads as 25 zero one, which is 2.50 to 1%.

The MP9100-2.50-1%through hole resistor is constructed using a thick film resistor element mounted between two metal lead frames. It is then covered with a resistive material that has excellent heat and temperature stability. The resistor is then soldered onto a substrate and sealed with a plastic material to ensure the highest reliability.

The MP9100-2.50-1% resistor is designed for operation over a wide temperature range, making it suitable for many military and space applications. It is also well suited for use in automotive applications where high power and high temperature operation is required. The resistor also has excellent electrical characteristics, making it a reliable choice for many industrial applications.

The MP9100-2.50-1% through hole resistor is a reliable device with high quality construction and excellent performance under a wide range of operating conditions. It is used in a variety of applications including military, aerospace, automotive, consumer electronics, medical and telecommunications.
