Enhanced Safety Capacitors (Class X1, X2, Y2)

Syfer / Knowles Enhanced Safety-Certified Capacitors (Class X1, X2, Y2) comply with international UL and TÜV specifications to provide designers the option of using a surface-mount ceramic multilayer capacitor to replace leaded film types. These capacitors offer the benefits of simple pick-and-place assembly, a lower profile, and reduced board space required. The FlexiCap™ version of these capacitors minimizes the risk of mechanical cracking. The lineup features a range of high capacitance values for selected case sizes. Syfer / Knowles Enhanced Safety-Certified Capacitors (Class X1, X2, Y2) are ideal for modems, AC-DC power supplies, and other applications where lightning strike or other voltage transients represent a threat to electronic equipment.
