Abstract

The invention discloses a low-temperature-coefficient metal film resistor. A resistor body comprises a base body, a metal film wrapping the outer side of the base body, a first electrode cap and a second motor cap, the first electrode cap and the second motor cap are connected to the front end and the rear end of the metal film, and the outer portion of the resistor body is coated with a paint layer; the rear end of the second motor cap is connected to the epoxy resin block through a protective tube, a T-shaped fixing plug inserted into the protective tube is arranged in the second motor cap,a limiting plug is inserted into the rear end of the interior of the protective tube, and the rear end of the pin penetrates through the T-shaped fixing plug, the protective tube and the limiting plugin sequence; the rear end of the limiting plug is inserted into a positioning hole in the epoxy resin block, and a fixing ring on the outer side of the rear end of the protection pipe is fixed to a groove in the front portion of the positioning hole through a screw. According to the invention, the protection effect on the pins is improved, so that the structure is firmer; the protection tube is firmly connected with the epoxy resin block, so that the pins are effectively protected; and heat generated when the resistor body works can be dissipated quickly.

Description

technical field [0001] The invention belongs to the technical field of resistors, and in particular relates to a metal film resistor with a low temperature coefficient and a manufacturing process thereof. Background technique [0002] With the rapid development of the electronics industry, electronic equipment has higher and higher requirements for high-precision, high-stability, and high-reliability electronic components, especially resistors. According to the material of the resistor film, resistors mainly include carbon film resistors and metal film resistors, etc. At present, the precision metal film resistors commonly found in the market have low precision and high temperature coefficient, resulting in low stability. They cannot meet the higher requirements of high-end electronic equipment, and their pin connections are not firm and easily damaged. Therefore, we propose a metal film resistor with a low temperature coefficient and its manufacturing process to solve the ...
