Susumu URG Series Ultra Precision Thin Film Chip Resistors

Susumu URG Series Ultra Precision Thin Film Chip Resistors have ±0.01% tolerance, ±2ppm TCR, and low noise THIN FILM (NiCr) construction. The URG series thin film resistors from Susumu are available in EIA standard case sizes 0805 and 1206 and are 100% lead-free. This series offers resistance range up to 68kΩ and maximum voltage of 200V.

Susumu RG Series Ultra Precision Thin Film Chip Resistors

Susumu RG Series Ultra Precision Thin Film Chip Resistors feature high reliability and excellent stability at different environmental conditions with resistance tolerances from ±0.02% to ±0.5%. With low noise, thin film (NiCr) construction, the RG series is ideal for automotive, test and measurement, optical, telecommunication, medical, and industrial equipment. The Susumu RG Series Ultra Precision Thin Film Chip Resistors are RoHS compliant and 100% lead-free (matte Sn termination finished).

Susumu RM Series Thin Film Network Resistors

Susumu RM Series Thin Film Network Resistors feature ultra accuracy with a relative resistance tolerance of +/-0.01% and relative TCR of +/-1ppm/°C. RM Series Thin Film Network Resistors from Susumu offer ultra reliability with 10,000 test hours of 85°C/85%RH at 155°C with less than+/-0.1% resistance drift. Applications include those that require a precise relative resistance ratio such as voltage dividers and gain-setting circuits for amplifiers.

Susumu KRL Series Precision Current Sensing Resistors

Susumu has expanded the KRL Series to include large resistive elements that evenly distribute heat. Susumu KRL Series Precision Current Sensing Resistors extend the resistance range from the existing RL / PRL series down to 1mΩ. The KRL series has improved TCR that is as low as ±50 ppm/ºC and is available in two geometries - longer side and shorter side terminal type - ranging from 1/3W to 5W power rating. Also available are types for high temperature applications (up to 170ºC) and for low thermal emf applications. The Susumu KRL Series Precision Current Sensing Resistors offer a face down mounting for accurate sensing. RoHS compliant, the protective coating is halogen-free.

Susumu PRL Series Current Sense Resistors

Susumu PRL Series Current Sense Resistors are very low resistance value chip resistors with long-side electrodes for high-precision current detection. Featuring excellent performance in resistance tolerance, noise, long term stability, and heat dissipation, the PRL series is useful in many current sensing applications. The Susumu miniature PRL series Current Sense Resistors are offered in 1/3, 1/2, 2/3, 1, and 2-watt power handling thin film resistors (PRL1632 are realized as 1W for 3.2x1.6mm [1206]).

Susumu YJP Series Current Sense Resistor Jumpers

Susumu YJP Series Current Sense Resistor Jumpers feature higher current 10A, less than 0.2 mohm of the resistance values, low ESL, and noise, and excellent performance for high frequency. Susumu YJP Series Current Sense Resistor Jumpers are RoHS compliant and 100% lead free.

Susumu PCMB/PCMC Series Power Choke Coil

Susumu PCMB/PCMC Series Power Choke Coils feature a small size of 7.3 mm x 6.6 mm and low tap of 3.0 mm maximum. Susumu PCMB/PCMC Series Power Choke Coils feature excellent loss characteristics and high saturation current. Applications include high speed drive DC/DC inverter for servers and routers, and CPU power for PCs.

Susumu PXV Series Thermo-Variable Chip Attenuators

Susumu PXV Series Thermo-Variable Chip Attenuators feature excellent high frequency characteristics. Susumu PXV Series Thermo-Variable Chip Attenuators are used for simplifying temperature drift compensation of GaAs high frequency amplifiers. Applications include base station and others.
