ATFL4220BU

Designed for automotive electronics, the ATFL4220BU by Amphenol PCD sets new standards for Terminal Blocks - Din Rail, Channel reliability in vehicle applications. The vibration-resistant construction and extended temperature range make it ideal for engine compartment and chassis-mounted installations.The Disconnect, Feed Through architecture provides essential ground path redundancy for automotive safety systems. The dual-isolation design prevents single-point failures in critical circuits.The Fuse, Lever feature enables quick disconnection during vehicle servicing. The tool-less operation complies with dealership service time requirements.With 2 contact points, this terminal block accommodates complex automotive wiring harnesses. The high-density layout reduces bulkhead penetration points by 40%.The 1 tiered configuration enables logical separation of power and signal circuits. This arrangement minimizes EMI coupling between sensitive automotive networks.The 8.0mm terminal size optimizes current density for automotive power distribution. The tin-plated brass construction resists fretting corrosion in high-vibration environments.Utilizing Screw technology, the connection system withstands 50G mechanical shock loads. The self-adjusting contact pressure compensates for thermal cycling effects.Rated for 6.3 A continuous load, the terminal meets automotive peak current requirements. The thermal mass design handles engine compartment temperatures up to 125 C.The 500V dielectric strength ensures reliable operation in 48V mild hybrid systems. The insulation material maintains properties across -40 C to 150 C temperature swings.UL-recognized for 6.3 A operation, the terminal block exceeds typical automotive electrical system demands. The current derating curve remains linear up to 105 C ambient.Tested at 220V per UL standards, the component withstands load dump transients common in vehicle electrical systems. The insulation resistance exceeds 100M after humidity exposure.Compatible with 10-22 AWG automotive-grade wiring, the terminals accommodate both thin-wall and high-temperature conductors. The strain relief feature prevents wire fatigue at connection points.Integrated LED provide diagnostic capabilities for modern vehicle architectures. These smart features interface with onboard diagnostic systems without additional wiring.The Blue housing meets automotive OEM color specification requirements. The matte finish reduces glare for improved service visibility.Designed for automotive 5mm x 20mm, 5mm x 25mm protection devices, the fuse holder meets IP6K9K dust and water ingress standards. The sealed construction prevents corrosion in underbody locations.
