The JT4-1121HL is a type of jack with magnetics that is used in modular applications. This type of modular connector is a component that can be used to quickly connect different types of communications media, such as coaxial cables and printed circuit boards. The modular jack with magnetics is designed to provide electrical isolation and protection from interference, as well as reduce crosstalk and noise.

The JT4-1121HL characteristics of the series include a pleasant environmental characteristic, a characteristic that is reliable over a long term, high heat resistance, high temperature rating, a wide operational frequency band, low insertion loss, low return loss (RL) and superior reverse isolation. Most of all, this kind of modular jack with magnetics has enhanced performance in both insertions and terms of reliability.

To ensure quality performance, the JT4-1121HL is built with a solid thermoplastic body and a plated brass shell. The body of the connector is constructed from a polyethylene insulated thermoplastic which reduces the effects of thermal expansion and contraction from temperature changes. The brass shell is both corrosion and tarnish resistant, giving the jack superior performance over rough environmental conditions.

The housing for the JT4-1121HL is a die-casted zinc alloy with a rough, portable finish. It is also designed with a grounding clip and a spin & lock mechanism for a secure mating. The pins are made from beryllium copper and gold plated for maximum corrosion resistance. The contacts have a maximum current rating of 1 ampere per pin, while the magnetic core has a maximum current rating of 3 amperes.

The working principle of the JT4-1121HL consists of two components. The first component is the jack itself, which is held in place by the locking mechanism. When a plug is inserted into the jack, the locking mechanism will feed electrons through the pins, thus enabling the magnetic field to surround the plug. The other component is the plated copper magnetic core, which is also known as the steel plate. This plate is placed around the plug and it serves as a shield against electromagnetic interference (EMI). The two components act together as an effective shield against EMI and provide better signal quality and data transmission.

The JT4-1121HL is widely used in a range of applications, such as commercial, industrial and consumer electronics, networking, military, medical, automotive, and telecommunications. It is often used for both analog and digital signals, allowing for high speed data transmission and long range signal reliability. It is also typically used for providing power and signal transfer between electronic components, such as between modules and PCBs. Due to its reliable performance and durability, the JT4-1121HL is an ideal choice for a variety of applications.
