Radial leaded MOV’s for general purpose overvoltage protection
Stackpole’s RV Series of radial leaded metal oxide varistors is available in a wide range of disk sizes and working voltages designed for general purpose overvoltage protection. The RV Series is UL1449 certified and offers disk sizes from 5mm up to 20mm with peak current ratings up to 18,000 amps and energy handling up to […]
Precision resistors offers resistance values from 10K Ω up to 50G Ω
The HGC Series from Stackpole utilizes high resistance materials and special patterning to achieve high resistance values with the capability of providing tight tolerances and low TCR. The HGC offers resistance values from 10KΩ up to 50GΩ . Sizes from 0402 through 3512 are available. For sizes 1206 and larger, the HGC Series offers absolute tolerance […]
HCS Series AEC-Q200 Qualified High Current Shunts
Stackpole’s popular HCS series is fully compliant with AEC-Q200. AEC-Q200 requires the resistors to have an operating temperature range of -55 degree C to +150 degree C and survive a wide range of electrical and mechanical stress tests. These tests include exposure to high temperatures, temperature cycling, high tem perature operational life, biased humidity, ESD, […]
Fusible wirewounds offer advanced pulse handling, failsafe operation
The WWF Series from Stackpole is a fusible wirewound technology. Wirewounds typically handle at least 5 times the pulse energy of similar film resistors. Although this attribute is ideal for surge handling, it creates a risk under continuous overloads where the part may continue to generate heat until igniting itself, the PCB, or surrounding components […]
612-size current sense resistors now offered in 2mΩ resistance value
Stackpole has expanded the value range of its CSRF0612 surface mount resistors. The 0612 size features terminations on the long side of the part for improved power handling, heat dissipation, and lower resistance values. The CSRF0612 handles 1.5 watts versus the equivalently sized 1206 chip that is only rated at 1 watt. This lower resistance […]
MELF resistor technology provides cooler operating temperatures at full-rated power
Stackpole’s MLF / MLFM is a series of metal film, surface mount MELF resistors. The MELF technology provides cooler operating temperatures than flat chip resistors at full rated power. For example, the MLFM1 will typically run more than 70 degrees C cooler than the equivalent 1W 2512 size flat chip resistor and has a smaller […]
Working with Wirewounds
by Kory Schroeder, Director of Product Marketing and Engineering, Stackpole Electronics Inc. For high currents, axial-leaded wirewound resistors are often good candidates because they can handle up to 10 W and double as fuses. When a task calls for dissipating kilowatts of power over an extended period, wirewound resistors are often a logical choice. These […]
Low Resistance Values Ideal for Portable Consumer Electronics
The CSRF Series is a surface mount current sense resistor series that utilizes foil on ceramic carrier technology. This structure allows for very low resistance values in small case sizes while maintaining good TCR. The 0402 size is available in the popular 10 milliohm value, while the 0603 size is available in values down to […]
