The CN custom through hole resistor network series from Exxelia Ohmcraft® provides a fully customisable solution for your resistor network needs. The CN series offers ohmic values up to 2GΩ, very low noise and ultra-high stability. It also offers tight ratio tolerances to ±0.1%, low absolute TCR to ±10 ppm/°C, a tracking TCR down to ±5 ppm/°C and a low VCR to 0.05 ppm/V. By utilising their patented Micropen® precision printing technology, FineFilm, Exxelia Ohmcraft are able to provide an entirely new level of performance and stability in custom leaded resistor networks. The long serpentine pattern used in manufacturing Exxelia Ohmcraft’s Custom Networks (CNs), coupled with the use of low ohms/ square thick film inks, makes it possible to create virtually any divider ratio. For example, Exxelia Ohmcraft produces 7 decade networks (20K to 20G ohm) with precision ratio tolerances.Due to the endless possibilities with the Exxelia Ohmcraft CN custom resistor network series, each requirement will be individually reviewed and a part number allocated upon approval. Please include the following information for any requirement:

• A schematic and physical diagram showing how all of the resistors interconnect
• The value of each resistor
• The desired TCR value (ppm/°C)
• Overall tolerance and the tolerances for each individual component value
• Type and length of leads
• Any other information necessary to the manufacture of the network
