Resistors and Capacitors
Stackpole develops 1% tolerance chip resistors
Stackpole Electronics, Inc. announced the addition of 1% tolerance to the popular RPC Series of thick film high pulse withstanding chip resistors. Previously this series was only available down to 5% tolerance due to the elimination of the calibration laser trim. Through proprietary materials and processing, Stackpole is now able to offer 1% accuracy with only minor sacrifices to the pulse power handling of the product.
AVX Expands MLCC family
AVX Corporation has expanded its extensive family of multilayer ceramic chips (MLCCs) to include gold plated terminations. Designated the Au Series, the RoHS compliant MLCC eliminates the use of tin and lead and subsequent tin whiskering events on the PCB. Available for most standard MLCC values, AVX offers a range of gold thicknesses for flash terminations (soldering applications) from 1.9μin to 7.87μin, while the gold Std termination thicknesses start at 100μin minimum (epoxy / wire bonding applications).
Stackpole’s HVC Series High Voltage Resistors Offer ESD Withstanding Up To 40KV
The HVC Series thick film high voltage chip resistors from Stackpole are designed to operate and withstand extremely high voltages which would destroy other standard and medium voltage resistors. The high resistance values in the HVC Series in standard chip sizes of 1206 and larger are rated for voltage handling above 15KV, and the 3512 size chip can withstand up to 40KV transients. This means that even repetitive ESD surges of 15KV will not significantly affect the performance of these resistors. Standard and medium voltage chip resistors can have ESD perfomance that ranges from good to completely unacceptable at 3KV and 10KV levels. This is due to the wide range of laser calibration trimming necessary to achieve the required tolerances for these series. However the HVC Series utilizes a unique direct deposition onto the substrate, which allows for the highest resistance values and highest voltage handling with typically very little laser trim calibration needed.
Stackpole’s Customizable SWT and EWT Series Tubular Wirewounds
Stackpole's SWT and EWT Series are high power tubular wirewounds that can be customized to fit many different applications. Along with the standard sizes, these two series can be provided with non-standard core sizes, adjustable center taps, non-inductive windings, different size mounting brackets, and different tab connectors. Many high power resistor applications require a resistor to fit into a fixed enclosure, housing, or space within another piece of equipment.
