FAQs
The TPS-20L uses a PCB tab configuration for straightforward surface or through-board mounting on telecom PCBs. With a 170 Vdc rating and 20 A current capacity, it matches common DC supply rails used in telecom and data-communication devices, supporting reliable insertion into standard fuse holders and board layouts while maintaining robust electrical contact through silver-plated ferrules.
Key specs include a 20 A amperage rating, 170 Vdc voltage rating, 100 kAIC interrupt rating, non-indicating status, and a glass melamine tube construction. Together, these characteristics deliver rapid current limiting during faults, high surge tolerance, and dependable operation in harsh telecom environments, reducing downstream damage and downtime.
Yes. The TPS-20L is CE Marked and RoHS compliant, aligning with common regulatory expectations for European and global telecom equipment. This simplifies compliance documentation, supports sustainable product design, and helps manufacturers meet end-market regulatory requirements during design reviews and audits.
Ideal for telecom PCB protection in line cards, network switches, and other DC-powered telecom assemblies. The PCB tab feature and compact dimensions suit dense board layouts, while the 100 kAIC interrupt rating provides protection against high-energy faults typical of telecom rack environments.
Because the TPS-20L is non-indicating, it minimizes nuisance visual checks; its high reliability reduces replacement frequency after surges. The robust 100 kAIC rating lowers the risk of collateral damage, translating to lower downtime costs and fewer spare parts requirements while maintaining regulatory compliance and supply chain predictability.
