Product catalog summary
Overview: The document provides comprehensive technical specifications and guidelines for various series of varistors by KEKO VARICON, including ZOV, ZOVR, SV, CV+, AV, ZV, PV/DV, OV, MV, and SMD series. These varistors are designed for surge protection in diverse applications such as industrial, automotive, and low voltage environments.
Product Description: The ZOV series includes standard-sized and custom-designed varistors, available as epoxy-coated or metalized blocks. Customers can specify parameters like operating voltage and clamping voltage. The ZOVR series offers round-shaped varistors for surge protection in outdoor and industrial settings.
Features: Varistors across the series offer a wide range of operating voltages, compliance with UL and CSA standards, and are lead-free. They are designed for high current and energy handling capabilities, with options for epoxy coating and metallized discs.
Custom Varistors: Custom-designed varistors allow for tailored electrical parameters and physical dimensions, with engineering support from KEKO VARICON.
Absolute Maximum Ratings: The document outlines maximum ratings for varistors, including voltage ranges, peak surge current, and temperature ranges. Varistors have a response time of less than 25 ns and high insulation resistance.
Device Ratings and Characteristics: Detailed tables provide specific ratings for various models, emphasizing the importance of proper soldering and coating to maintain characteristics.
General Technical Data: Technical data for custom-designed varistors include threshold voltage range and temperature behavior, with physical design options available.
Specifications: The document lists specifications for different series, including operating voltage ranges, model sizes, and temperature ranges. It highlights compliance with relevant standards and environmental considerations.
Protection Level and Pulse Rating Curves: Protection levels are specified for different model sizes under demanding conditions.
Ordering Information: Details on ordering standard and custom-designed varistors, including marking and coding for specifications.
Reliability and Lifetime: Reliability is defined by the ability to function under various conditions, with mean life influenced by voltage and temperature factors.
Soldering Recommendations: Guidelines for soldering techniques, including wave and infrared reflow processes, and recommendations to avoid thermal shock.
Packaging and Lead Styles: Information on packaging options and lead styles for compatibility with automatic insertion equipment.
Disclaimer: KEKO VARICON reserves the right to change specifications without notice and disclaims responsibility for product use or patent infringements.
