TPH×××-R Series

Product catalog summary

Overview
The iTCO (idea Thermal CutOff) TPHxxx-R Series is a non-resettable thermal fuse designed for over-temperature protection in various applications such as electric motorcycles, golf carts, yachts, home energy storage, and base station power supplies. It features low impedance, low power consumption, and is RoHS and REACH compliant.

Specifications
The series supports a rated current of 20 A, a rated voltage of 400 VDC, and a rated functioning temperature of 150°C. The fusing time is controlled to be ≤ 60 seconds.

Product Structure
The iTCO consists of components like flux resin, thermal element, alloy thermal-link, electrode, feed heater, sealant, and lead wire, all housed in plastic or ceramic.

Dimensions
Key dimensions include a length of 23.0 mm, width of 18.0 mm, and height of 11.2 mm, with various tolerances specified.

Part Number System
The part number system includes parameters such as rated voltage, current, and operating voltage, with specific codes for each configuration.

Usage and Installation
Ensure operating conditions are within specified voltage and current limits. Avoid direct contact with the device when powered to prevent burns or electric shock. Proper mechanical and electrical connections are crucial to prevent abnormal heating.

Soldering Guidelines
Soldering should adhere to specified conditions to avoid premature opening of the control circuit. A heat sink fixture is recommended for severe soldering conditions.

Packaging
Packaging includes trays, PE bags, and cartons, with specific dimensions and quantities outlined.

Glossary
Definitions for terms like Main Circuit (MC), Control Circuit (CC), Rated Current (Ir), and others are provided to clarify technical specifications.

Attention
Operating conditions, electrical connections, and storage guidelines are emphasized to ensure product reliability and safety.

idea Thermal CutOff TPHxxx-R Series Description Features idea Thermal CutOff (iTCO) is a fuse that uses low melting point alloys as the electrical connection point of the main circuit, with built-in heater as the control circuit, to achieve controlled fusing function. idea Thermal CutOff (iTCO) is consist mainly of Flux Resin, Thermal Element, Alloy Thermal-Link, Electrode, Feed Heater, Sealant and Lead wire, sealed in plastic or ceramic housings. idea Thermal CutOff (iTCO) is mainly used in the protection of new energy security, and secondary protection for charging and discharge circuits. idea Thermal CutOff (iTCO) mainly uses two electrodes which are connected with the thermal element of the fusing elements as electrical connections with passive temperature-sensing fusing actions. At the same time, Built-in heater with independent over-temperature protection heats the thermal element, provides sufficient heat to the fuse, cuts off the main circuit and disconnects the control circuit to achieve self-protection.
