Effective Testing Methods for CDRH-R Magnetically Shielded Inductor

Q Factor Test

Q factor is a dimensionless parameter that indicates the quality and efficiency of an inductor. It is defined as the ratio of the inductive reactance to the resistance of the inductor at a given frequency. A higher Q factor means a lower power loss and a sharper resonance peak. To perform a Q factor test, you need to apply an alternating current (AC) signal to the inductor and measure the voltage across it. The Q factor can be calculated by dividing the frequency by the bandwidth of the voltage peak. The reading should be within the acceptable range for the intended application of the inductor.

ESR Test

ESR is the sum of all the resistive elements in an inductor, including the wire, the core, and the solder joints. ESR is measured in ohms and varies with frequency. A lower ESR means a higher efficiency and a lower temperature rise of the inductor. To perform an ESR test, you need to apply a high-frequency AC signal to the inductor and measure the voltage drop across it. The ESR can be calculated by dividing the voltage drop by the current. The reading should be as low as possible for the inductor to function properly.

Ring Test

A ring test is a qualitative method that can reveal the presence of any defects or irregularities in the inductor. To perform a ring test, you need to connect the inductor in series with a resistor and a capacitor to form a resonant circuit. Then, you need to apply a pulse signal to the circuit and observe the waveform on the oscilloscope. The waveform should show a smooth and symmetrical ringing pattern, with no distortions or spikes. If the waveform is abnormal, it means the inductor has some faults or imperfections that affect its performance.

Maintenance of CDRH-R Magnetically Shielded Inductor

Moisture and dustproof
If the working environment is relatively harsh, protective measures should be taken, such as using a sealed housing or coating to prevent moisture and dust from entering the inductor.

Regular inspection and maintenance
Inspect the inductor regularly to check whether there is any abnormality such as damage or discoloration on the appearance, and measure whether its parameters are within the normal range.

Packing & Transportation

Packaging	Protective film, cardboard box, wooden crate
Shipping	By logistics; by shipping; by air.

FAQ

Q: When to use shielded inductors?

A: Shielded inductors are often required for sys- tems that require low-noise operating conditions. Examples include applications where the inductor is located near oth- er electronic components that are sensitive to EMI, such as precision analog circuits, microcontrollers, or sensors.

Q: What is the difference between shielded and unshielded inductors?

A: Shielded inductors are manufactured to fully encapsulate the coil in a form of magnetic shielding. With unshielded inductors, the coil windings are typically exposed or otherwise magnetically not shielded. These are generally the worst offenders from an EMI perspective due to the unhindered propagation of EM fields.

Q: Can we use an inductor in an AC circuit?

A: An inductor can oppose or block the passage of current through it. There are two cases to do so. One case is for the DC circuit, and another is for the AC circuit. The first inductor is connected to a DC supply, and the second one is connected to the AC supply.

Q: Do inductors block high frequency?

A: At high frequency the inductor becomes a high impedance element that can be used for RF isolation. High frequency cannot pass through the inductor, but dc current and very low frequency signals are allowed to pass.

Q: How can we guarantee quality?

A: Always a pre-production sample before mass production; Always final Inspection before shipment.
