Melf resistors designed for harsh environmental conditions

Melf resistors designed for harsh environmental conditions
Stackpole has recently introduced the MLFA Series of metal film melf resistors. The MLFA Series is fully AEC-Q200 compliant and offered in the 0204 (0.4W) and 0207 (1W) sizes. The MLFA has exceptional stability demonstrated over life, biased humidity, and short time overload testing. In addition, the MLFA offers pulse power handling up to 3500 watts for single short duration pulses, and lightning surge withstanding up to 6KV for resistance values above 100K ohms.

Ultracapacitors operate in tough conditions

Ultracapacitors operate in tough conditions
Durable under adverse conditions, Nesscap’s XP-series has been specially engineered for applications that operate over long durations in environments with high temperature and humidity. They are available at Rutronik. Under the ‘Biased Humidity Test’ conditions (2.7V, 90% relative humidity, 60°C), the XP-series stands out with a significantly longer service life under direct current conditions in comparison with standard cells.
