PTC-Fuses

Product catalog summary
Introduction
This catalogue from SIBA GmbH & Co. KG presents a comprehensive range of Positive Temperature Coefficient (PTC) fuses, crucial for electronic applications. These fuses are designed to safely interrupt excessive currents and automatically reset once the fault condition is cleared. The catalogue highlights the versatility of SIBA's fuses across various sectors, including IT, telecommunications, household appliances, and industrial applications.
General Information
The document provides detailed specifications for PTC fuses, including parameters such as hold current (Ihold), trip current (Itrip), maximum voltage (Umax), and maximum current (Imax). It explains the significance of these parameters in ensuring the reliable operation of electronic devices.
Product Range
The catalogue lists various types of PTC fuses, each with specific characteristics and applications. The product range includes fuses with lead wires and Surface-Mount Device (SMD) configurations, catering to different design requirements.
Technical Specifications
Each fuse type is accompanied by detailed technical specifications, including construction materials, packaging options, and environmental specifications. The document also provides information on the resistance values (Rmin, Rmax, R1max) and the time to trip (ttrip) for each fuse type.
Environmental and Testing Standards
The catalogue outlines the environmental specifications for the fuses, such as operating and storage temperature ranges, resistance to thermal shock, and compliance with various international standards like UL 1434 and IEC 62391-1. It also details the testing methods used to ensure the durability and reliability of the fuses.
Conclusion
SIBA emphasizes the importance of selecting the right fuse for specific applications and offers expert assistance for custom solutions. The catalogue is designed to help customers navigate the selection process and ensure the safety and efficiency of their electronic systems.
Overview
This document provides technical specifications for various types of self-resetting fuses (PTC-Fuses) manufactured by SIBA GmbH & Co. KG. It includes details on construction, electrical characteristics, environmental specifications, and approvals.
Construction
The fuses are made with epoxy insulating material (UL94V-0) and tin-plated copper lead wires. The diameter of the lead wires varies based on the holding current (Ihold).
Electrical Specifications
  • Maximum Current (Imax): Ranges from 3 A to 40 A depending on the type.
  • Maximum Voltage (Umax): Ranges from 30 V to 90 V, with some types having an interrupt voltage up to 600 V.
  • Holding Current (Ihold): Varies from 0.04 A to 9 A across different types.
  • Trip Current (Itrip): Typically double the Ihold value.
  • Resistance: Minimum and maximum resistance values are provided for each type, indicating the range of resistance before and after tripping.
  • Time to Trip (ttrip): Specified in seconds at a given current, indicating how quickly the fuse will trip under overload conditions.
Environmental Specifications
  • Operating and Storage Temperature: -40 °C to +85 °C.
  • Passive Aging: Conducted at 85 °C for 1000 hours with a typical resistance change of ±8%.
  • Humidity Aging: Conducted at 85 °C and 85% relative humidity for 1000 hours with a typical resistance change of ±8%.
  • Thermal Shock Resistance: Tested from 125 °C to -55 °C, 10 times, with a typical resistance change of ±12%.
  • Solvent and Vibration Resistance: No change observed under specified test conditions.
  • Solderability: Tested at 220°C for 3 seconds, with resistance to soldering heat at 260 °C for 10 seconds.
Approvals
The fuses have various approvals including UL 1434, IEC 62391-1, and VDE 0898-1, with some types requiring specific requests for certain approvals.
Figures and Dimensions
The document includes figures illustrating the dimensions of the fuses, with maximum and typical measurements provided for each type.
