| 1 | When ordering, please specify termination and packaging codes: e.g. HA4158-BLD | |
| Termination: | L = RoHS compliant tin-silver over copper. Special order, added cost: T = RoHS tin-silver-copper (95.5/4/0.5) or S = non-RoHS tin-lead (63/37). |
|
| Packaging: |
D = 13" reel, machine-ready EIA-481 embossed plastic tape (400 parts per full reel). B = Less than full reel In tape, but not machine-ready. To have a leader and trailer added ($25 charge), use code letter D instead. |
|
| 2 | Maximum power into specified load that causes less than a 40°C temperature rise. Measured at 1 kHz with a 14.4 Vdc supply for the 2-Ohm load and a 21 Vdc supply for the 4-Ohm load. Output Power table shows typical output conditions. Tested using TAS5414A evaluation board from Texas Instruments. | |
| 3 | Inductance is for each winding, measured at 100 kHz, 1.0 Vrms, 0 Adc using an Agilent/HP 4284A impedance analyzer. | |
| 4 | DCR is for each winding, measured on a micro-ohmmeter. | |
| 5 | SRF measured using Agilent/HP 8753D network analyzer. | |
| 6 | Total harmonic distortion + noise measured at 20 W into a 2-Ohm or 4-Ohm load at 1 kHz with a 21 Vdc supply. | |
| 7 | Isat: DC current (typical) at which the inductance drops the specified amount from its value without current. | |
| 8 | Irms: Current applied to windings connected in series that causes the specified temperature rise from 25°C ambient. | |
| 9 | Ambient temperature range: | –40°C to +125°C with Irms current, +125°C to +165°C with derated current |
| 10 | Storage temperature range: | Component: –40°C to +165°C T&R packaging: –40°C to +80°C |
| 11 | Resistance to soldering heat: Three reflows at >217°C for 90 seconds (+260°C ±5°C for 20 – 40 seconds), allowing parts to cool to room temperature between. | |
| 12 | Electrical specifications at 25°C. | |
| Refer to Soldering Coilcraft Components before soldering. | ||
