How trimming affects thick-film resistor performance

February 16, 2022 By Kory Schroeder Leave a Comment

thick film resistors

Ordinary thick-film resistors can display varying qualities depending on how the manufacturer elected to trim the device. It pays to know what to look out for. Kory Schroeder, Stackpole Electronics Inc. Surface-mount thick-film chip resistors are the predominant type of resistor in electronic circuits today. This technology is inexpensive; thick-film resistors are produced by screen-printing […]

Four-terminal shunts provide precision current sensing

February 2, 2022 By Redding Traiger Leave a Comment

Low resistance values are important for high-efficiency current sensing because lower values mean less wasted power on the current sensing measurement itself.  But sensing low resistance values accurately becomes challenging because of lead resistance errors. Using a four-terminal shunt resistor eliminates the detrimental effects of lead resistance on the current sensing measurement operation. The HCSK1216 provides […]

Thermal challenges with high-power resistors

October 12, 2021 By Kory Schroeder Leave a Comment

resistors

Shrinking component sizes have complicated the task of ensuring temperatures stay below their allowable maximum. Kory Schroeder • Stackpole Electronics Inc. Electronic components of all types continue to shrink in size. In response, resistor manufacturers are devising resistors with higher power ratings but which come in commonly used sizes. Of course, when more power gets […]

High-current, four-terminal shunt resistors now in 1216 and 4026 sizes

March 11, 2020 By Aimee Kalnoskas Leave a Comment

HCSK series

Low resistance values are important for high-efficiency current sensing in that lower values mean less wasted power on the current sensing measurement itself. But sensing low resistance values becomes challenging because of lead resistance. Using a four-terminal shunt resistor eliminates the detrimental effects of lead resistance on the current sensing measurement operation. Stackpole recently added […]
