Despite the convenience and availability of LEDs, the neon lamp still has a viable position as a power-on indicator as well as use in some specialty applications. This part continues the exploration of the neon lamp. Q: Are there more details of the various operational phases? A: Yes, the entire glow process has been studied […]
High-power sense resistors feature high temperature stability
For current sensing applications requiring high efficiency, low resistance values are required. Typically, high power sense resistors are very large and have TCR in the 200 to 400 ppm range. Stackpole’s HCSM2818 is rated at 5 watts and now provides a 2 milliohm resistance value with a TCR of 100 ppm. This ensures the HCSM2818 is stable at […]
The humble neon lamp: down, but definitely not out: Part 1
Despite the convenience and availability of LEDs, the neon lamp still has a viable position as a power-on indicator as well as use in some specialty applications. The classic neon indicator lamp with its reddish-orange glow has been used since the early 1990s. Now, the availability, convenience, longevity, and other attributes of LED-based indicators have […]
