Overview
The Littelfuse 2035 is a subminiature surface mount fuse belonging to the FLAT-PAK 202 Series. It features a low-profile rectangular package available in gull-wing surface mount or DIP configurations for through-hole mounting. The device provides overcurrent protection with a voltage rating of 250 VAC and an ampere rating of 2A. Electrical characteristics include a minimum opening time of 4 hours at 100% of the ampere rating, a minimum opening time of 1 second at 200% of the ampere rating, and a maximum opening time of 30 seconds at 202% of the ampere rating.
Feature Summary
- Offers both fast-acting and Slo-Blo versions within the Flat-Pak design family
- Available in gull-wing surface mount or DIP through-hole configurations
- Features UL recognition and CSA certification under the Components Program
Applications
- Protection of printed circuit boards and integrated circuits from shorts and overcurrent events
- Overcurrent protection in battery chargers and electronic ballasts
- Circuit protection in AC-DC and DC-DC power converters
Procurement Notes
Verify the specific ordering suffix against official Littelfuse documentation to confirm the exact physical configuration (gull-wing vs. DIP) and blowing characteristic (fast-acting vs. Slo-Blo). Ensure the selected variant matches the required mounting method and electrical timing specifications for the target application circuit.
Selection Notes
Select this component based on the 250 VAC rating and 2A current capacity requirements. Confirm whether the application demands a fast-acting response or a time-delayed Slo-Blo characteristic. Verify that the chosen package style aligns with the PCB assembly process, as the series offers distinct gull-wing and DIP options.
Part Context
This part belongs to the Littelfuse FLAT-PAK 202 Series, which are subminiature fuses designed for surface mount and through-hole applications. The series is characterized by its low-profile rectangular package and 250 VAC rating, serving as a compact solution for protecting sensitive electronics in various industrial and consumer devices.
Replacement Considerations
Consult Littelfuse documentation for confirmed substitute part numbers within the 202 Series or compatible FLAT-PAK variants. Do not assume generic equivalents match the specific opening time curves or agency approvals without verifying against official cross-reference data.
