Susumu's proprietary NiCr based alloy exhibits excellent TCR characteristics as compared to other resistive materials such as tantalum nitride. Despite the belief that NiCr thin film has reliability issues, especially in humid environment, Susumu has developed technologies to apply an inorganic passivation coating that acts as a hermetic seal. The result is an ultimate thin-film resistor that far exceeds even thick film resistor reliability.
RG series thin-film chip resistors boast high precision, near zero TCR and unprecedented reliability with all the benefits of thin-film resistors.
