Low noise, high voltage chip dividers now available up to 4KV
High voltage applications frequently require high resistance value resistors with the ability to handle high working and overload voltages. Engineers may have difficulty finding thick film chip resistors with the required precision for applications requiring tight resistance tolerance and TCR tracking. For precision high-voltage applications, a high-voltage divider chip can be beneficial. Stackpole’s new HVCD […]
FAQ on pull-up/pull-down resistors: part 2
Even this relatively simple circuit arrangement has subtleties that affect performance. Part 1 explored the role of pull-up and pull-down resistors to ensure that the binary (digital) circuit points are at an unambiguous 1 or 0 level. This part explores basic issues of sourcing, sinking current, and resistor sizing. Sourcing and sinking current Q: What […]
FAQ on pull-up/pull-down resistors: part 1
Even this relatively simple circuit arrangement has subtleties that affect performance. In the crisp, clean, theoretical binary world, signals exist in only two unambiguous states, generally called 1 and 0 (one and zero). However, when engineering students, hobbyists, and digital-only professionals get into the hands-on real world of circuits and systems, they find that binary […]
0201-size, automotive-grade resistors bring enhanced reliability in consumer and industrial applications
Many types of electronic devices now benefit from the higher reliability of automotive grade resistors. By specifying automotive grade resistors, design engineers in any market segment can increase electrical stability and environmental reliability without the significant increase in cost normally associated with established reliability resistors. Stackpole’s RMCA series is AEC Q200 qualified and provides excellent long-term reliability. The […]
The why and how of matched resistors: part 2
Paired resistors with low-temperature drift are critical to many precision analog circuits. The previous part discussed the need and “why” for matched resistors, as well as errors due to tolerance and TCR. This section transitions to their physical embodiment and looks at the “how” of obtaining needed matched resistors to minimize errors, temperature-related effects, and […]
The why and how of matched resistors: part 1
Paired resistors with low-temperature drift are critical to many precision analog circuits. Achieving high performance, precision, and consistency in an analog signal chain requires attention to subtle details. In many cases, these details include the absolute accuracy of passive components such as resistors and the more subtle effects on component characteristics due to aging, mechanical […]
Resistors provide improved reliability for automotive and industrial applications
Many types of electronic products across a variety of market segments require higher reliability components. Automotive grade resistors offer increased reliability and improved performance without the high cost and limited availability of components procured to established reliability military specifications. For those applications that also require a defined pulse withstanding the options become limited. Stackpole’s RPCA […]
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 […]
EC-Q200 qualified automotive-grade chip resistor is also anti-sulfur and lead-free
Stackpole introduces the RMEA Series, an automotive grade chip resistor that is not only fully lead-free but also AEC-Q200 qualified and anti-sulfur. Automotive grade chip resistors adhere to higher materials and process standards as well as 100% AOI to ensure the consistent performance and long-term reliability that general-purpose chip resistors cannot guarantee. The RMEA is […]
