1. What are the main features of DE1B3KX681KA4BN01F?
DE1B3KX681KA4BN01F is a 680 pF ceramic safety capacitor with ±10% tolerance and a 250 VAC rated voltage. It is a radial leaded disc capacitor classified as a Class X1/Y2 safety capacitor. The component supports an operating temperature of up to 125°C, uses flame-retardant epoxy resin meeting UL94V-0 requirements, and provides high dielectric strength. Its compact construction also helps save PCB and installation space compared with larger conventional safety capacitors.
2. What is DE1B3KX681KA4BN01F used for?
DE1B3KX681KA4BN01F is mainly used for AC-line noise suppression and safety isolation in electronic equipment. Typical applications include power supplies, household appliances, industrial equipment, chargers, and other products where electromagnetic interference needs to be controlled while maintaining the required safety insulation. Its X1/Y2 safety classification makes it suitable for applications where the capacitor is connected across or from the AC line to protective earth, subject to the applicable circuit and safety requirements.
3. Does DE1B3KX681KA4BN01F have any alternative manufacturer and part number, such as?
Yes. Similar X1/Y2 ceramic safety capacitors are available from manufacturers such as TDK, Vishay, KEMET, and Panasonic. Potential alternatives may include TDK CK1 series, Vishay VY1 series, or KEMET safety-certified ceramic capacitors with comparable capacitance and voltage ratings. However, an alternative should not be considered a direct replacement without checking the safety classification, capacitance tolerance, rated AC voltage, impulse withstand capability, lead spacing, package dimensions, temperature rating, and applicable safety certifications.
4. Is technical support available for DE1B3KX681KA4BN01F?
Yes. Technical documentation and application information are available for Murata's safety capacitor products. Engineers can refer to the relevant specifications for electrical characteristics, safety classifications, insulation requirements, temperature ratings, and mechanical dimensions. When selecting a replacement or designing an AC-line filtering circuit, it is important to verify the required X1/Y2 classification and applicable safety standards rather than selecting a component based only on capacitance and voltage ratings.
