The SMD Multi-Layer Ceramic Capacitor, Safety Cap from Knowles Precision Devices is designed to meet international UL and TvúV specifications, making it suitable for applications requiring safety certification. It is available in various sizes including 1808, 1812, 2211, 2215, and 2220, and is approved for mains AC voltages up to 250Vac. The capacitors are classified under Y2/X1, X1, and X2 categories, ensuring compliance with relevant safety standards. These capacitors offer a capacitance range from 4.7pF to 22nF, with temperature coefficients available in C0G/NP0 and X7R types. The C0G/NP0 variant provides a stable capacitance with minimal change over temperature, while the X7R variant allows for a ¬±15% variation across a temperature range of -55¬8C to +125¬8C. The capacitors also feature a high insulation resistance of 100G,Ѷ and a dielectric withstand voltage suitable for various applications. The surface mount design facilitates easy pick-and-place assembly, reducing board space and assembly costs compared to traditional through-hole components. A FlexiCap,Ñ¢ option is available to minimize the risk of mechanical cracking. This product is particularly suitable for use in modems, AC-DC power supplies, and environments where voltage transients may pose a risk to electronic equipment.
Safety Certified capacitors comply with international UL and TÜV specifications to offer designers the option of using a surface mount ceramic multilayer capacitor to replace leaded film types.
Offering the benefits of simple pick-and-place assembly, reduced board space required and lower profile, they are also available in a FlexiCap™ version to reduce the risk of mechanical cracking.
Knowles’s high voltage capacitor expertise means the range offers among the highest range available of capacitance values in certain case sizes.
Applications include: modems, AC-DC power supplies and where lightning strike or other voltage transients represent a threat to electronic equipment.
