Coilank International Ltd Taiwan launched and mass production the several kinds of tiny SMD power inductors/RF inductors and common mode choke to meet the portable /wireless device needs . The mobile devices applied COILANK components with the characteristic of low profile, low Rdc, and high current handling capacities. The magnetically shielded structure that ensures the high-density mounting configurations with flat bottom surface ensure secure and reliable mounting.
In the new generation of wireless mini PCI and multifunctional mobile devices, COILANK has the more advanced inductors with excellent function to achieve the higher power conversion efficiency. The PIN2510 has lunched and mass production for over one years with 2.5*2.5*1.0mm and outstanding IDC/ Irms to resolve power management issues of the new applications need, such as GPS, mobile phone, blue tooth, USB power device, and so on. The related combo including LCD series as well as PIN2010 is your best solution for the needs of downsizing and thinning mobile devices nowadays.
COILANK R&D and production team has applying its great experience tobalance the trade-off between size and efficiency in tiny wire wound power inductor, RF inductor and common mode choke for related IC's needs of the wireless/portable systems at present. Lower profile, lower loss and higher Current in Compact Size is the design guide of our R&D principles to design such inductors which made by unique automatic process. The present qualified product lines of tiny SMD power /RF inductor combo to fit customer needs of tiny electronic systems are proving what we are doing is not only the right things but also the contribution to save the energy for our children.
COILANK's experienced technology and operation team, with its active, positive, responsible spirit in conjunction with first-class quality control, manufacturing and R&D equipment to supply domestic and overseas customers. We are well prepared to face the industry generation change and ever-competing market trend of lighter, thinner, shorter and tinier.

Inductor Definition

1.1 An inductor (also choke, coil or reactor) is a passive two-terminal electrical component that stores energy in its magnetic field. For comparison, a capacitor stores energy in an electric field, and a resistor does not store energy but rather dissipates energy as heat.
Any conductor has inductance. An inductor is typically made of a wire or other conductor wound into a coil, to increase the magnetic field.

When the current flowing through an inductor changes, creating a time-varying magnetic field inside the coil, a voltage is induced, according to Faraday''''''''s law of electromagnetic induction, which by Lenz''''''''s law opposes the change in current that created it. Inductors are one of the basic components used in electronics where current and voltage change with time, due to the ability of inductors to delay and reshape alternating currents.

1.2 Inductance coil :Increasing current in a coil of wire will generate a counter EMF which opposes the current. Applying the voltage law allows us to see the effect of this EMF on the circuit equation. The fact that the EMF always opposes the change in current is an example of Lenz''''''''s law. The relation of this counter EMF to the current is the origin of the concept of inductance. The inductance of a coil follows from Faraday''''''''s law.
