SUSUMU’s low noise and anti-sulfur thin film structure provides long term stability due to an additional protective layer (inorganic passivation). Characteristics of the resistors are a very low resistance tolerance (±0,05%) and TCR value (±5ppm/°C). The parameters indicate that the RG / HRG / KRL series, all of which are part of our stock-deal program with superb shipping conditions, are very suitable for various automotive, medical or measurement electronics.

RG Series

The RG series ensure anti sulfur and low noise. It is especially reliable on long term against high temperature, humidity and impurities. The characteristics of SUSUMU's resistors are, thanks to an additional protective layer (inorganic passivation), a tolerance of ±0,02% to ±0,5% and a low TCR of ±5ppm/°C. After testing the RG series for 10.000 hours on reliability, the resistance value drift less than ±0.1%. The SUSUMU RG series is RoHs compliant and 100% lead-free.

The main application benefits various high quality industrial, medical and measurement instrumentations and machines. It’s also AEC-Q200 qualified for automotive grade components.

Product Benefits:

·        Long term stability because of protective layer(inorganic passivation)

·        Less than ±0.1% drift after 10.000 hours of reliability test

·        High precision resistance tolerance: ±0.05%, very low TCR: ±5ppm/°C

·        Thin-film structure enabling low noise and anti-sulfur

Market Applications:

·        Automotive electronics

·        Industrial measurement, instrumentation, industrial machines

·        Various sensors, medical electronics


HRG Series

Derived from the RG series, the HRG series was developed. It has a 4x higher rated capacity with the same high precision and reliability of the RG series. The increased performance and heat dissipation is made possible by a wider contact.

The HRG series is characterized by its long term stability in harsh condition. It is suitable for applications where high performance is needed along with high precision and reliability, like robotics, direct current motors and inverters.

The SUSUMUS’ HRG series is RoHs compliant and also 100% lead-free. It ensures anti-sulfur and low noise also further advantages of the thin-film-technology. It comes with a standard size of 1206 and 2512.

Product Benefits:

·        Thin film structure enabling low noise and anti-sulfur

·        Precision resistance tolerance: ±0.1%, low TCR: ±25ppm/°C

·        Long term stability due to SUSUMU thin-film structure

Market Applications:

·        Power source related devices

·        DC motors
