Hirose has designed an innovative FPC-to-board/board-to-board connector series that offers high density mounting and space-savings. Supporting USB4 Gen2 (10Gbps) transmission for a wide range of portable electronic and consumer devices, the DF40 Series combines a 0.4 mm pitch with a mounting depth of only 3.68 mm.
The robust DF40 Series connector features a superior stamped contact design with a clear tactile click that confirms secure mating. The stamped contacts enable a longer effective mating length of 0.45 mm that provides shock and vibration resistance common to portable device applications. Further protecting signal contacts, the DF40 Series has curved contacts to prevent buckling during mating.
The DF40 Series is available in a number of versions with stacking heights ranging from 4.0 mm down to 1.5 mm. The DF40 FPC-to-board connector family includes a high-temperature version, a positive lock version, EMC shielded versions and versions with or without retention tabs.
Easy mating is achieved via a wide self-alignment range of ±0.33 mm in the pitch direction and ±0.33 mm in the width direction. The contact area is enclosed in a housing to protect against solder waste and flux during mounting process. Solder wicking is prevented via a nickel barrier.
The DF40 Series is available in a wide range of positions ranging from 10 to 120 depending on the variations. The connector has a rated voltage of 30V AC and a standard operating temperature of –35° to 85° C. The high-temperature version is rated up to 125° C.
