The 4198ADH1K00019 is an contact parts used for RFI and EMI electric isolation, conductivity and to prevent leakage. It consists of contacts, fingerstocks and gaskets, and is commonly used in power and signal coupling application field.

The contact of 4198ADH1K00019 includes Hard Gold Finger and Solder Bucket (SB) contact. The Hard Gold Finger contact is made from domestically manufactured pre-tin-plated phosphor bronze and is tested to 200 mating cycles, making it suitable for mission critical devices. It offers better durability and contact resistance over the conventional soft gold contact, and also offers electrical and thermal conductivity. The Solder Bucket Contact is also domestically manufactured and press fit with tin-plated conductive clip – making it ideal for high current and high power applications.

The fingerstock of 4198ADH1K00019 is made from domestically manufactured pre-tin-plated phosphor bronze. It has precise radius and angle on both internal and external surfaces, and is tested to meet stringent requirements for mating and conductivity. The fingerstock offers excellent adhesion for components and conductivity between the contact and fingerstock, making it suitable for high reliability applications.

The gasket of 4198ADH1K00019 is made from fluoroelastomer to meet the required protection standards – such as an IP67 rating – for dust and water ingress protection. The gasket also provides the necessary protection against electro-magnetic interference (EMI). It can also be used as an electrical insulation on metal surfaces, helping to reduce the leakage current between components and provide circuit protection.

The working principle of 4198ADH1K00019 is as follows. When the contact and fingerstock are mated, the hard gold contact provides electrical and thermal conductivity, while the fingerstock provides the adhesion for components and conductivity between the contact and fingerstock. The solder bucket contact provides high current and high power connections between components. The gasket then provides the necessary protection against dust, water and EMI, while also providing electrical insulation on metal surfaces.

In summary, the 4198ADH1K00019 contact parts are ideally suited for power and signal coupling applications, and are used for RFI and EMI electric isolation, conductivity and to prevent leakage. They feature a Hard Gold Finger contact, a Solder Bucket contact, a fingerstock made from pre-tin-plated phosphor bronze, and a fluoroelastomer gasket. They offer excellent adhesion for components, electrical and thermal conductivity, protection against dust, water and EMI, and circuit protection, making them suitable for high reliability applications.
