Product catalog summary
Overview:
This document provides comprehensive technical specifications for various types of fuses, including quick-acting and slow-blow fuses. It covers materials, functional characteristics, testing parameters, and product codes.
Specifications:
  • Quick Acting Fuse: Available in ratings from 0.5A to 10A at 250V AC and 125V AC. Detailed parameters include resistance, average voltage drop, current, average power dissipation, and average I2t values.
  • Slow Blow Fuse: Available in ratings from 200mA to 5A at 250V AC and 125V AC, with similar detailed parameters as quick-acting fuses.
Materials:
  • Fuse bodies are constructed from either ceramic or glass tubes.
  • End caps are made from nickel-plated brass.
Procedures:
To select the correct fuse code, refer to the temperature/current diagram. Consider factors like maximum product temperature (Tp), safe temperature range (Th), self-heating, and ventilation.
Standards and Recommendations:
Maintain a space of more than 3mm between the thermal cutoff and conductors. During soldering, do not exceed Tf-24°C. Avoid using fuses in liquids or poisonous gases. The minimum order quantity is 1000 pieces.
Functional Characteristics:
The document details the testing current, current range, and blow time for different percentages of rated current. For example, at 100% rated current, the blow time can range from 4 hours to milliseconds depending on the fuse type and current range.
Key Data from Tables:
Tables provide fuse codes with voltage, resistance, average voltage drop, current, average power dissipation, and I2t values. For instance, the FUS37F0025US-P has a resistance of 1.460 Ω and an average voltage drop of 810 mV at 0.250A.
Precautions:
Do not connect heaters directly to the thermal cutoff. Ensure the temperature of the area where the cutoff is connected remains below Th under standard conditions.
Additional Information:
Specifications are subject to change without prior notification. Contact information is provided for further inquiries, and a minimum order quantity of 1000 pieces is noted for certain products.
