Product catalog summary
Overview: The KEKO VARICON 2015 catalogue details specifications for protective devices such as varistors, varicons, and capacitors. It highlights the company's right to modify specifications without notice and advises verifying data sheets before ordering.
Varistors: The catalogue includes SMD, THD, high energy, and automotive varistors. Key parameters are maximum steady state applied voltage (Vrms and Vdc), peak single pulse surge current, and energy absorption levels. Custom designs are available.
Varicons: These include multilayer SMD and THD varicons with dual function options, designed for specific applications with customizable parameters.
Capacitors: The catalogue lists safety class X and Y disc capacitors, high voltage disc capacitors, and RFI suppression ceramic capacitors, detailing capacitance range, voltage ratings, and termination types.
SV Series - Special Medium Voltage Varistors: Features lead style epoxy coated varistors with AC operating voltages from 60 V to 550 V, offering high current and energy capabilities with low clamping voltage. Custom designs are available.
Device Ratings and Characteristics: Tables provide ratings for SV series models, including operating voltages, surge current capabilities, and dimensions. Custom designs and specific models are available upon request.
Key Features: Products are designed for high reliability with low clamping voltage, broad current and energy handling capabilities, and compliance with UL and CSA standards. Available in various sizes and configurations.
Specifications:
  • Varistor Threshold Voltage (Vn): 100 to 910 V at 1 mA.
  • Steady State Applied Voltage: DC 85 to 745 V, AC 60 to 550 V.
  • Transient Characteristics: Peak Single Pulse Surge Current > 5500 A/cm², Single Pulse Surge Energy > 400 J/cm³.
  • Clamping Voltage: < 1.9 times the DC voltage.
  • Temperature Behavior: Operating -40 to +85 °C, Storage -40 to +125 °C.
Design and Size Parameters: Varistors are available in square and rectangular shapes with epoxy coating and lead styles. Size ranges from 3x3 mm to 23x23 mm, with various lead spacing and wire diameters.
Ordering Information: Detailed breakdown of ordering codes, including series name, maximum continuous operating voltage, Vn tolerance, surge current code, packaging type, and lead style.
Pulse Rating Curves: Includes pulse rating curves for different model sizes, illustrating protection levels under various conditions.
Packaging: Varistors are available in bulk, tape, and reel packaging options, with specific quantities per package depending on model size.
Additional Notes: KEKO VARICON reserves the right to change specifications without notice. Customers are advised to verify data sheets before ordering. The document emphasizes accuracy and reliability but disclaims responsibility for its use.
Product Overview: Technical specifications and packaging details for KEKO VARICON's ZV, AV, CV, CV+, and SV series components, available in reel, bulk, and ammo pack.
Packaging Specifications: Lists packaging units for different series and sizes, indicating the number of components per package type.
Technical Specifications: Provides dimensions and specifications for different model sizes, including carrier tape width, hold-down tape width, sprocket hole position, and lead spacing.
Assembly Recommendations: Guidelines for handling through-hole components to prevent damage during lead bending and soldering.
Soldering Guidelines: Outlines resistance to soldering heat and provides a Pb-free wave soldering profile.
Terminology: Definitions for technical terms related to varistors, aiding in understanding operational parameters and limitations.

SPECIAL MEDIUM VOLTAGE VARISTORS - SV SERIES Description The SV series is a series of lead style epoxy coated square or rectangular shaped varistors with an AC operating voltage ranging from 60 V to 550 V. There are two groups of these varistors. The first consists of square shaped varistors with extremely high current and energy capabilities and a low clamping voltage, providing an increased level of protection necessary for the transients expected in telecommunication and AC power networks. Compared to electrically equivalent disc varistors, SV varistors come in smaller nominal dimensions....
