Woking, United Kingdom, April 25, 2018 — TT Electronics, a global supplier of engineering electronics products for the manufacture of performance-critical applications, today announced the availability of two new resistors that extend and enhance its high-performance CR and HR series products. The two latest versions of the thick film chip resistors use a smaller 0603 size, thus providing more opportunities for compact circuits that need to ensure performance and space.
For the aerospace, military, communications, medical and industrial markets, these two resistor series thick-film devices are more tolerant of surges than thin-film resistors, and their reliability is also greatly improved. CR0603 Resistors The available parameter values of the device range from 1R0 to 10M, the tolerance value is as low as 0.1%, and can be optionally produced in accordance with CECC 40401-008 (European Electronic Components Council 40401-008 specification). In addition to military and aerospace applications The two products can also be used for other specific applications, including submarine repeaters, host systems, and high reliability systems. Available parameter values for HR0603 resistors range from 10M to 20G, tolerance values as low as 5%, and can be supported Multiple applications, including high-gain amplifiers, infrared and glass break sensors, as well as smoke, gas and medical monitors.
TT Electronics has introduced the optional screen printing technology CR series resistors to improve the reliability of resistors and reduce practical application failures. In addition, for circuit designers who need to ensure the reliability of critical circuits within a compact printed circuit board The failure rate of this type of resistor is lower than the competitor's product. There are currently seven sizes available - from 0503 to 2512. The CECC-approved resistors are also available as short-circuit links.
Circuit designers who need to achieve a stable high ohmic value in a compact printed circuit board space typically use a connected multi-chip solution. Compared to such solutions, the HR series high-ohm value resistors have higher reliability and practical application. Less failures. These types of resistors have lower voltage coefficients, are versatile, and can be custom-designed and dimensioned. The power dissipation of high-resistance devices is usually very low. Therefore, the rating of such devices is only determined by the voltage factor, and the size is the smallest. The 0503 resistor is rated at 50V, and the largest 1206 resistor is rated at 200V. There are currently five sizes.
Both of these resistor series have a nickel barrier on the soldering tip to ensure excellent 'percolation leach' performance and solderability, and can withstand continuous immersion of solder at 260°C for 30 seconds. The series of products are specified for ambient temperatures ranging from -55 to +155°C and are well-structured with a thick film of resistive material with a glazed organic protective layer (screen printed on a 96% alumina substrate). CR and HR series products have gold wire or welding end, inner packaging or reel contains all the relevant identification information.
