Resistors optimised for conductive adhesive bring tiny SMD outlines to specialised applications
New chip resistors optimised for use with conductive adhesives, from TT electronics, maintain performance at high temperature up to 200°C and in applications such as hybrid microcircuits or medical MRI scanners where non-magnetic components must be used.
The Conductive adhesive is preferred for assembling some types of hybrid microcircuits, non-magnetic electronics and equipment designed to operate at temperatures capable of melting ordinary solder. These include down-hole drilling equipment, as well as military, aerospace and automotive assemblies. TT electronics GCR series resistors are compatible with most approved adhesives, and allow a mechanically strong bond with low electrical resistance. The resistors, when optionally supplied with no organic materials, are also suitable for applications requiring low outgassing, such as scientific equipment and space instruments.
Designers can choose from devices with 1% or 5% tolerance, to fulfil a variety of application requirements. The temperature coefficient of 100ppm/°C (200ppm/°C for values below 10?) ensures outstanding stability throughout the specified operating temperature range from -55°C to +200°C.
Major features of GCR series resistors:
* Standard 0805, 1206, 2010 and 2512 chip sizes
* Planar gold (G type) or platinum-silver (P-type) electrodes
* Polymer-silver (EW type) or gold/nickel-barrier (GW type) wraparound coated options
* Non-magnetic (G, P & EW types)
* Operating temperature range -55°C to 200°C
