Safety Certified Ceramic Capacitors/High Voltage

Product catalog summary

Overview: This document is a technical catalog for Safety Standard Certified Ceramic Capacitors and High Voltage Ceramic Capacitors, published on April 7, 2014. It includes specifications, certifications, and guidelines for handling and usage.

Compliance and Safety: All products comply with EU RoHS, restricting hazardous substances in electrical equipment. Users are advised to read ratings and cautions to prevent hazards like smoking or burning.

Product Specifications: Capacitance is expressed in pico-farads (pF) using a three-figure code. Products are categorized by insulation type and class, such as Type KY (Basic Insulation) and Type KX (Reinforced Insulation).

Certifications: Products are certified by various international standards including UL, CSA, VDE, and others. Specific certifications are listed for different voltage ratings and product types.

Features and Applications: Compact size with high dielectric strength, suitable for AC line filters and power supplies. Coated with flame-retardant epoxy resin, conforming to UL94V-0 standards. Not recommended for automotive power train or safety equipment unless specified.

Packaging and Marking: Available in various lead styles and packaging options like Ammo Pack Taping and Bulk. Markings include type designation, capacitance tolerance, and manufacturing codes.

Test Methods and Data: Specifications and test methods are detailed for each series, ensuring compliance with safety standards. Typical characteristics data and packaging details are provided for both safety certified and high voltage capacitors.

Important Notes: Users are advised to read the ratings and cautions for storage, operating, soldering, mounting, and handling to prevent issues like smoking or burning. The catalog provides typical specifications, and users should approve product specifications before ordering.

High Voltage Ceramic Capacitors - DES Series: Features include low dissipation factor suitable for power supplies with increased switching frequency, improved allowable power in the 100 to 300kHz band, and operating temperature range up to 125°C. Applications include high-frequency pulse circuits such as snubber circuits for switching power supplies.

Specifications and Voltage Considerations: DC-rated capacitors used in AC or ripple current circuits must maintain the Vp-p value within the rated voltage range. Irregular voltages during circuit start or stop due to resonance or switching should be considered, ensuring the capacitor's rated voltage range includes these variations.

Operating Voltage and Temperature: The surface temperature of capacitors should remain below their rated operating temperature. Self-generated heat from high-frequency or pulse currents should not exceed 20°C above ambient temperature.

Withstanding Voltage Test Conditions: Test equipment should simulate a 50/60Hz sine wave. The voltage should be applied gradually from near zero to avoid defects. A zero-cross method is recommended to prevent surge voltage issues.

Fail-Safe Measures: Capacitors may fail as a short circuit. Implement fail-safe functions like fuses to prevent electric shock, fire, or fuming.

Storage and Operating Environment: Capacitors should not be stored in corrosive atmospheres or exposed to moisture. Storage conditions should be within -10 to 40°C and 15 to 85% humidity. Use capacitors within six months of delivery.

Soldering and Mounting: Avoid exceeding solder heat resistance specifications. Soldering should be done with a maximum iron-tip temperature of 400°C, 50W wattage, and 3.5 seconds duration.

Vibration and Impact: Capacitors should not be exposed to excessive shock or vibration. Secure them on circuit boards using adhesives or coatings.

Cleaning: Ultrasonic cleaning should be limited to 20 watts per liter and 5 minutes maximum to prevent lead wire fatigue.

Capacitance Change and Performance Check: Capacitors may experience aging and capacitance changes due to temperature or voltage. Verify equipment performance and surge-proof ability before use.

Quality Certifications: Manufacturing plants have obtained ISO9000 quality system certification.
