SMRH125 Shielded Smd Power Inductor 5D28 2.6 3 4.2 100uh PCB Coil
Inductor
Product performance:
The shielded chip inductor is different from the general chip inductor. The general chip inductor is not shielded in the circuit. When used, the inductor cannot achieve the desired effect in the circuit, and the shielded chip inductor can be shielded. The instability of current in some circuits plays a good role in blocking. The metal shield with complete shielding inductance will surround the positive conductor, and the inner side of the shield will induce the same amount of negative charge as the charged conductor. The same amount of positive charge as the charged conductor appears on the outside. If the metal shield is grounded, the positive charge on the outside will flow into the ground, and there will be no electric field on the outside, that is, the electric field of the positively charged conductor is shielded in the metal shield.
Attributes:
Chip inductance is a property of a closed loop. When the coil of the chip inductor passes current, the chip inductor forms a magnetic field induction in the coil, and the induced magnetic field will generate an induced current to resist the current passing through the coil. The role of the chip inductor in the circuit is to generate a changing magnetic field when an unsteady current is passed, and this magnetic field will in turn affect the current. , It is high resistance to high frequency pulses, so it plays the role of passing DC resistance AC pulses.
Feature:
1. The flat bottom surface is suitable for surface mount.
2. Excellent end face strength and good solderability.
3. It has the characteristics of high Q value and low impedance.
4. The characteristics of low leakage flux, low direct resistance
and high current resistance.
Application:
Products are widely used in digital products, PDAs, notebook computers, mobile phones, network communications, graphics cards, LCD backlights, power modules, automotive electronics, security products, office automation, home appliances, walkie-talkies, electronic toys, sports equipment and medical equipment, etc.
