All are mechanically rugged and magnetically shielded, but each series offers unique performance benefits.
| Family | Unique Performance |
|---|---|
| XGL | Lowest DCR, highest current ratings and features soft saturation Widest range of inductance values Runs cooler than its counterparts |
| XAL XEL |
The highest current ratings and features soft saturation |
| XFL | Low loss, traditional saturation Most suitable for lower power applications |
The easiest way to choose is by using our Power Inductor Finder and Inductor Analysis & Comparison tool. They'll show performance under your exact operating conditions (current, ripple, temperature, etc.)
The soft saturation characteristic provides the XGL, XEL and XAL higher saturation that the XFL, making them ideal for applications requiring high peak current withstanding capability.
The XGL and XEL offer the lowest AC loss, making it the best choice for high switch frequency power converters. The XGL features the lowest DCR and the lowest total power losses for the same operating condition.
| Inductance (µH) | DCR typ (mOhms) | Isat (A) 30% | |
|---|---|---|---|
| XGL4020 | 1 | 8.2 | 8.8 |
| XEL4020 | 1 | 13.25 | 9.0 |
| XAL4020 | 1 | 13.25 | 8.7 |
| XFL4020 | 1 | 10.8 | 5.4 |
The power loss curves shown above are based on real measurements. Please use our Coilcraft Core and Winding Loss Calculator to analyze and compare the performance of these series in the condition of your applications.
Along with the lowest DCR, XGL4020 has increased Irms by 60% compared to XEL/XAL. Giving it the ability to run much cooler under the same operating conditions.
For example, at 80°C ambient for the conditions below, the part temperature of the XGL4020 is 30°C less!
IDC = 8 A, 40% ripple = 3.2 A, Freq = 1 MHz
| Inductance (µH) | DCR typ (mOhms) | Irms (A) | Part Temp @80°C | |
|---|---|---|---|---|
| XGL4020 | 1.0 | 8.2 | 12 | 101°C |
| XEL4020 | 1.0 | 13.25 | 9.6 | 128°C |
| XAL4020 | 1.0 | 13.25 | 9.6 | 131°C |
In the graph below, core loss remains constant for the Coilcraft inductor compared with dramatic core loss increases caused by thermal aging for other manufacturer's inductors after only 1500 hours at 155°C.
