Eaton TPS-3L Telecommunication Fuse - 100 kAIC
Part Number: TPS-3L
Quick Summary
TPS telecommunication fuse by Eaton provides fast-acting overcurrent protection for telecom PCBs. Engineers often struggle to protect sensitive telecom electronics without increasing board size or sacrificing fault tolerance. Certified CE marked and RoHS compliant, the TPS-3L also delivers a 100 kAIC interrupt rating and a 170 Vdc rating for robust performance in high-current telecom environments. Its compact PCB tab design and 3 A rating simplify mounting on standard PCBs while helping reduce BOM complexity. Together with Eaton support and documented specifications, it enables reliable protection, faster integration, and lower total cost of ownership in telecom power paths.

Eaton Specification Sheet - TPS-3L
Feature: 3 A current rating provides precise overcurrent protection for low-power telecom rails, reducing heat buildup and protecting delicate components. Business Impact: Lower risk of PCB damage and field failures translates to reduced maintenance costs and shorter downtime in critical networks. Application: Ideal for power rails in telecom switches, edge devices, and remote radio units. Feature: 170 Vdc voltage rating supports independent DC distribution in telecom backplanes, enabling safe operation across common telecom power architectures. Business Impact: Enables wider compatibility with DC supply rails and improves protection margins, reducing the chance of nuisance trips. Application: On-board protection for DC- powered line cards and control boards. Feature: 100 kAIC interrupt rating delivers high fault-current protection, preserving upstream equipment and minimizing cascading failures. Business Impact: Improves system reliability in dense telecom deployments and data center edge gear. Application: Protection near power entry points in racks and cabinets. Feature: PCB tab termination with a glass melamine tube and silver-plated ferrules offers robust, vibration-resistant mounting. Business Impact: Durability in harsh environments and longer service intervals, lowering maintenance cycles. Application: Board-level fuse integration in telecom panels. Feature: Non-indicating fuse with standard packaging reduces BOM cost and simplifies replacement logistics. Business Impact: Streamlined inventory and faster field swaps without dedicated indicators. Application: Mass deployment in multi-site telecom deployments. Feature: Compliance with CE marking and RoHS directive ensures regulatory alignment for global deployments. Business Impact: Accelerates cross-border procurement and reduces compliance risk. Application: International telecom installations and equipment housings.
