Overview
The Littelfuse Inc. 06R075BU is a PolySwitch resettable PTC fuse belonging to the POLY-FUSE USBR series. It features a radial disc package designed for through-hole mounting. The device has a maximum voltage rating of 6V and a hold current (Ih) of 750 mA. This component functions as a polymeric overcurrent protection device, offering resettable protection in low-voltage circuits.
Feature Summary
- Polymeric construction providing resettable overcurrent protection capabilities
- Radial leaded disc package configuration suitable for through-hole PCB mounting
- Designed for low-voltage circuit applications with specific hold current ratings
Applications
- Low-voltage electronic circuit protection
- USB port overcurrent protection
- Peripheral device input protection
Procurement Notes
Verify part status carefully as this specific model may be obsolete. Confirm exact hold current and voltage ratings against current design requirements. Ensure compatibility with existing PCB footprint and thermal management strategies. Check for available replacement alternatives within the same manufacturer series if discontinuation is confirmed.
Selection Notes
Select based on strict adherence to the 6V maximum voltage and 750 mA hold current specifications. Evaluate thermal dissipation requirements for the radial disc package. Consider the resettable nature of the PTC technology versus one-time fuses for maintenance accessibility. Verify RoHS compliance and material safety declarations for end-use regulations.
Part Context
This component belongs to the POLY-FUSE USBR series from Littelfuse Inc., specializing in polymeric resettable fuses. These devices are engineered for compact, low-voltage protection scenarios where space constraints and reset functionality are critical. The series typically targets consumer electronics and portable device power lines.
Replacement Considerations
Consult official Littelfuse documentation for direct cross-reference or recommended substitute part numbers within the POLY-FUSE family. Ensure any replacement matches the radial disc form factor and electrical ratings.
