Inductance value and tolerance,DCR, saturation current (Isat), temperature rise current (Irms), package size, package method.
The saturation current(Isat) is based on the inductance, which decreases to 30% . The current passing through the inductor is defined as the saturation current(Isat),
Temperature rise current(Irms) to temperature as a benchmark, temperature rise to 40℃, the inductor temperature reached a constant, at this time through the inductor current for temperature rise current(Irms).
- The storage condition of the product in the package: the temperature is 5-40℃, the relative humidity is less than or equal to 70% , if take out to use, the remaining product please use the plastic bag seal to preserve according to the above condition, avoid the terminal (electrode) oxidation, affect the state of welding.
- Please do not keep the product in high temperature, high humidity, dust, corrosive gas environment.
We usually define the tolerance with specific letters in inductor naming .such as the following tolerances of power inductors, J: 5% ; K: 10% ; M: 20% ; N: 30%.
The heat-shrink sleeve has no effect on the inductor performance, but with the heat-shrink sleeve can better protect the coil, and can increase the voltage resistance of the inductor.
At present, we have the RI series type inductors, RI0507 inductors, RI810 type inductors are produced with heat-shrink sleeve.
Zxcompo Inductor doesn’t have defined the rated voltage because most of the inductors are used in the low-voltage DC-DC convector. For any applications in which inductor high-voltage is required, please contact ZXcompo.
- The peak current in inductors application circuit exceeds the inductors rated current.
- For two-in-one inductor heating, the coil and core short circuit.
- The inductor is applied at the wrong frequency. Each core has a suitable application frequency at which loss is minimal.
- MN-ZN inductors are used in high voltage circuits larger than 300V. For example, manganin inductors can produce heat when used in half-bridge/full-bridge resonant circuits.
Shielded inductors can better protect wires, circuits and coils from external magnetic fields, as well as reduce the electromagnetic field generated by the circuit on other components of the interference.

The symbols for chip beads and inductors in a circuit are the same, but they are different devices. The magnetic beads are in ohms (Ω) and the inductors are in Hines (H) .
Chip beads are made of oxygen magnets, inductors are made of cores and coils, chip beads convert AC signals into heat energy, inductors store AC and slowly release it, so inductors store energy, magnetic beads are energy conversion devices.
Chip beads mainly solve the problem of radiation interference, signal line multi-use magnetic beads, some high-frequency circuits such as RF, oscillating circuit, DDR SDRAM and so on need to add chip beads in the power supply input part.
Inductors mainly solve the problem of conduction interference, high-frequency inductors are mainly used in low-and medium-frequency filter circuit, RF matching, etc.
