Johanson Technology Inc. 0900FM15D0039001E is listed under the Ceramic Filters category and is commonly used when correctness, reliability, and qualification repeatability matter. Engineers evaluate saturation current, DCR, frequency response, and thermal rise to avoid hidden performance collapse under load. They are widely used to reduce conducted emissions, protect sensitive analog/RF blocks, and clean up switching regulator ripple. In RF designs, filtering controls out-of-band energy and improves coexistence with nearby radios and high-speed digital noise. In sensor nodes, clean power rails improve ADC performance and reduce false triggers due to supply ripple. Overall, it improves predictability by keeping key performance stable across manufacturing variance and operating conditions.
