TYA-Low Profile High Current SMT Power Inductor TYA4012 Series FEATURES AND APPLICATIONS Laird TYA series high current power inductors improve performance, reliability and power efficiency. A lower profile benefits consumer electronics, industrial and telecom design. Products feature extremely low DCR with greater efficiency and enable a large current in a small size. Inductors are of magnetic shielding and wire wound construction and perform in operating temperatures ranging from -40 C to 125 C including self-heating rise in temperature. FEATURES Magnetic shielded structure Low DCR and high efficiency Low profile and small size Metal alloy core with high saturation APPLICATIONS DC-DC Converter and Power Suppliers LCD TVS and Gaming Console Tablet, Notebooks, Servers and Printers Networking and Data storage GPS, Set-top-box and Base stations Smart meters and Medical instruments PART NUMBER EXPLANATION T Y A 4 0 1 2 4 R 7 M - 1 0 Tolerance % Inductance Product series Product size Standard value code (i.e. M: 20%) code code Catalog P.N (i.e. 4R7: 4.7 ELECTRICAL SPECIFICATIONS Tolerance: M: 20% or N: 30% Inductance tested at 1MHz, 1.0Vrms Heat Rated Current (Irms) is defined based on temperature rise approximate 40C (ambient temperature 255C) Saturation Current (Isat) is the DC current at which the inductance drops off approximately 30% from its value without current. (ambient temperature 255C) Operating temperature range: -40C~+125C (including self-heating temperature rise) Storage temperature range (packaging conditions): -10C~+40C and RH 70%(MAX.) Note: Heat Rated Current (Irms) is tested on a typical PCB and apply a constant current in still air. The temperature rise is dependent on the application system condition including PCB PAD pattern, trace width and thickness and adjacent components etc. Its suggested to verify the temperature rise of the component under the real operation application conditions.Laird Performance Materials Shielded Power Inductor www.laird.com TYA4012 Series Rev: A SPECIFICATION 1.MECHANICAL & DIMENSIONS (UNIT: mm) A 4.000.30 B 4.000.30 C 1.30 Max 3.300.30 D E 1.20 REF F 1.60 REF G 3.70 REF H 1.60 REF I 1.30 REF REMARK 2.PART NUMBER NOMENCLATOR: D: Inductance Tolerance.
