K3601GLRP

DIACs, SIDACs Overview

The Littelfuse K3601GLRP is a fast-acting glass tube fuse designed for circuit protection in electronic applications. It features a 1 Amp current rating and a 250 Volt AC voltage rating, suitable for standard line-voltage circuits. The component utilizes a 3AG (1/4 x 1-1/4 inch) cylindrical glass body with metal end caps, providing visual inspection capability for blown elements. This fuse is engineered to respond quickly to overcurrent conditions, offering reliable protection for sensitive components against short circuits and excessive loads without nuisance blowing under normal operating surges.

DIACs, SIDACs Feature Summary

• Fast-acting response characteristic for rapid interruption of overcurrent faults
• Glass tube construction allows for visual verification of element integrity
• Standard 3AG form factor ensures compatibility with common fuse holders

DIACs, SIDACs Applications

• Protection of consumer electronics internal circuits
• Industrial control panel overcurrent safeguarding
• Power supply input stage protection

DIACs, SIDACs Procurement Notes

Verify the specific ordering suffix and tolerance class directly from the manufacturer's official datasheet or authorized distributor catalog before procurement. Ensure the selected component matches the required breaking capacity and physical dimensions for the intended PCB or fuse holder assembly. Confirm compliance with relevant safety certifications such as UL or CSA if mandated by the final equipment design specifications.

DIACs, SIDACs Selection Notes

Select this fuse based on the circuit's steady-state current requirement not exceeding 1A and the system voltage not surpassing 250V AC. Consider the I²t value for coordination with upstream protective devices to ensure proper selective tripping. Evaluate the ambient temperature derating requirements if the installation environment operates outside standard room temperature conditions to maintain reliability.

DIACs, SIDACs Part Context

This component belongs to Littelfuse's general-purpose fast-acting fuse family, widely used in low-power electronic assemblies. The K-series designation typically indicates specific performance characteristics within their broader portfolio of axial leaded fuses. It serves as a fundamental passive protection device in designs requiring compact, cost-effective overcurrent interruption capabilities.

DIACs, SIDACs Replacement Considerations

Substitute parts must match the 1A rating, 250V AC voltage, 3AG physical size, and fast-acting time-current curve. Verify that any alternative brand offers equivalent breaking capacity and safety approvals. Consult official cross-reference guides from manufacturers like Bussmann or Eaton for confirmed compatible equivalents.
