Chip resistors available for high-power GaN battery management
For GaN-based battery management for consumer electronics and computer peripherals, the demand for high power and precision is escalating. While a variety of technology options offer lower resistance values suited for these applications, all-metal element resistors, like Stackpole’s CSS/CSSH Series, remain a popular choice despite their higher cost and wider tolerance range of 1% and […]
How trimming affects thick-film resistor performance
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
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 […]
Thin-film resistor comes in compact package
Stackpole Electronics’ CSRT2512-UP was developed to provide accurate, high-power current sensing for consumer and industrial electronic devices that exceed the capabilities of most 2512 case sizes available in the industry. The AEC-Q200 compliant CSRT2512-UP has unique thin-film material properties and processing to provide higher continuous power ratings and higher pulse power ratings than other thin […]
Thermal challenges with high-power 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
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 […]
