➀ The author seeks advice on replacing vintage 1985 Philips capacitors (X-capacitor and MKT type) in a motor controller board after previously replacing a faulty tantalum capacitor;
➁ Details include concerns about the polyester-paper X-capacitor's reliability and uncertainty about the MKT capacitor's specifications;
➂ Asks the community to determine if these aging components require replacement for safety and functionality.

➁ 新款 MLCCs 提供七种尺寸，扩展了 Vishay 现有的高电压 MLCCs 的电容范围。
➂ 这些 MLCCs 使用超稳定的 C0G (NP0) 介电材料，并提供多种应用，包括能源、工业自动化、消费电子和电信基础设施等。
TDK has introduced Class-X2 EMI suppression capacitors, the B3292x series, which are 20% smaller and more humidity resistant than previous models. The series meets Grade III Test B for temperature, humidity, and bias and is available in sizes ranging from 18 x 5 x 10.5mm to 42 x 14 x 25mm with values from 0.1 to 4.7µF. The capacitors are rated for 305Vac and can handle a maximum 630Vdc continuously, with operating temperatures from -40 to +110°C.
➀ Wurth is offering vibration-resistant versions of its surface-mount aluminium electrolytics and aluminium hybrid polymer capacitors.
➁ These new capacitors can withstand up to 30g of acceleration due to their enlarged solder pads and thicker base plates.
➂ The capacitors have been tested beyond IEC 60384-4 standards and are suitable for use in tools, industrial equipment, construction machinery, and drones.
