100C4R7BW2500X – ATC

The ATC 100C4R7BW2500X is a ceramic multilayer capacitor designed for high-frequency applications. It features a capacitance value of 4.7 pF with a tolerance code of ‘B’, indicating a ±0.1 pF tolerance. The ‘W’ case size denotes specific physical dimensions, typically around 0.055″ x 0.055″ (1.4mm x 1.4mm), influencing its self-resonant frequency and suitability for miniaturized circuits. The 2500X termination indicates a nickel barrier with solder plating, optimized for reliable solderability and resistance to leaching during reflow processes. Given the “ATC D/C: 15+ NON-ROHS” designation, this part was manufactured in date code 2015 or later and does not comply with the Restriction of Hazardous Substances (RoHS) directive, meaning it may contain lead or other restricted substances. This characteristic must be considered for applications requiring RoHS compliance.
