SDTR1503 ; 5.75x3.6x2.5(max dimensions coated version) SMD Drop Resistant Transponder Coil (900pH - 9.00 mH) Fa g Features § The SDTR1503 Series of Surface Mount ferrite wound inductor was designed to offer 3 more sentivity than SDTR1103 series (up to 45% more). It is specially recommended = when larger reading distance is needed or operations with metalic parts around the coil S decrease the magnetic performance of the coils. § The construction is the same of the SDTR1103 series and offer a good mechanical B. performance with excellent electrical and magnetical behaviour. ig FE Main characteristics: Q -Same stability in temperature of SDTR1103. & -High mechanical performance. -High sensitivity. 40mV/A/m for 1.82mH (@125KHz). 98mV/A/m for 7.2mH (@125KHz). -Epoxy coated. Moulded with epoxy protection, 5 sides protected , high reliability with Pick&Place machines warranted. Taped & Reel: 3000pcs / reel.
