(HI82)

Token non-magnetic SMD resistor (HM) series, applied to the field of medical high magnetic fields, such as electronic circuits located in magnetic resonance (MRI) and computed tomography (CT), or in the extreme environment of oil and gas industries, such as downhole instruments for oil wells, or flight control in aerospace applications.

(HM) SMD Resistor series its junction area does not contain nickel, they are made of metal alloy PtAg, can be used as thick film slurry, suitable for roll coating or impregnation process to the packaging chipset parts area. The standard SMD soldering process can also be used in the bonding process of silver conductive epoxy resins. The bonding technology of conductive epoxy resin is mainly used in the case of welding technology can not be applied, such as the temperature sensitive component which is affected by the high welding temperature, or the semiconductor without cladding on the same board. PtAg terminals are suitable for high temperature welding applications, which can be higher than the 155°c of typical soldering.

Similarly, (HM) chip resistors do not contain organic materials, no tin or tin lead layer, and resistance and conductive layer at 850°c high-temperature sintering, so the resistor chip will not have a substantial change, and has a stable electrical characteristics. The terminal material also affects the VCR (the voltage coefficient of the resistor), which is an important characteristic of the high-voltage resistor, and lower VCR is also designed for the Token of the non-magnetic SMD resistor.

Token non-magnetic thick flim chip resistor (HM) series, it consists of two main categories: (HMM) Precision High Value Chips and (HMS) Conventional Precision Megohm Chips. Sizes are 0402, 0603, 0805, 1206, 1210, 2512, and 4020 available. Resistance range from 100KΩ to the highest value 10TΩ. Operating voltage can reach 6000V. Precision tolerance has 0.25%/0.5%/1%/2%/5%/10%/20%/30% alternative. The temperature coefficient is low to 25ppm/°c. The voltage factor VCR can be specified within the range, from low to 25ppm/v.

(HM) chips compliant with RoHS and lead-free standards. Provide more competitive prices and fast delivery services. For technical requirements and special applications outside the specification, please contact the business representative of the Token Electronics.
