What are Terminals and Terminal blocks?

SNK Terminals are a type of industrial control terminal that is used in industrial automation, process control, and other applications. These terminals are designed to provide a secure and reliable connection between the user and the machine. They are typically used to control machinery, monitor production processes, and manage data. SNK Terminals are available in a wide range of sizes and configurations, allowing them to be used for many different types of applications.

Modular terminals are components that can be used to connect two or more devices together in a network. They are typically used to connect computers, servers, routers, switches, and other network devices. Modular terminals are often referred to as RJ-45 connectors because they use an 8-pin RJ-45 connector.

A terminal block is a type of electrical connector used to connect two or more wires together. It typically consists of a metal or plastic housing containing multiple terminals, which are the points at which the wires are connected. Terminal blocks are commonly used in industrial and commercial applications to provide a secure connection between electrical circuits.

Schurter STTP 9550: Three-Terminal Fuse

Schurter Three-Terminal Fuses (STTP) for Battery Systems

Intelligent Fuse Solutions for Battery Systems

Ultra-Low Contact Resistance for High Efficiency
High Contact Reliability for Low Signals
Enhanced Wear Resistance for Long‑Term Contact Integrity
Supports Miniaturization and High‑Power Density Design

The Schurter three-terminal fuses STTP 9550 combine conventional overcurrent protection with an actively triggered overcharge protection function, providing an additional layer of safety for lithium-ion battery systems.

In addition to current-dependent interruption, the integrated trigger terminal enables controlled activation in critical operating conditions. This allows reliable disconnection of charge and discharge paths even in the event of protection IC or FET failure.

Gold-plated terminals ensure low and stable contact resistance, high signal integrity, and
excellent corrosion resistance. The compact package supports high-power-density battery pack
designs ranging from 1 to 24 cells.

Applications:
Typical applications include energy storage systems, power tools, UPS equipment, e-bikes, e
scooters, and automated guided vehicles (AGVs). Supported by UL approvals and designed for
redundant protection architectures required by modern battery safety standards, three-terminal
fuses provide a robust and intelligent protection solution for advanced energy systems.

Schurter PPTC Resettable Fuses: Compact Protection for Maximum Reliability

PPTC: Compact Protection for Maximum Reliability

The new PPTC series PFTA, PFTB, PFTC and PFTL provide reliable resettable overcurrent
protection for modern electronic applications. In the event of a fault, the polymer PTC device
automatically increases resistance to effectively protect systems against overloads and short
circuits — without replacing fuses.

The portfolio includes radial leaded and SMD versions with current ratings from 0.05 to 5 A and
voltage ratings up to 72 V. UL-compliant flame-retardant materials and compatibility with
automated assembly processes make these series ideal for industrial high-volume applications.

Applications:
Typical applications include energy storage systems, power supplies, industrial electronics,
consumer electronics, automotive systems, wearables, SSDs and Li-ion batteries. The compact
PFTL SMD series additionally enables space-saving designs with high integration density.
