| 1 | When ordering, please specify tolerance, termination and packaging codes: e.g. 4312RV-725XGLD | |
| Termination: | L = RoHS compliant gold over nickel over phos bronze 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" machine-ready reel EIA-481 embossed plastic tape (3000 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 | Inductance and Q measured using Agilent/HP 4192A impedance analyzer at125 kHz. For recommended test procedures, contact Coilcraft. | |
| 3 | Read distance measured using the KEELOQ® Transponder Evaluation Kit part number DM303005 from Microchip. Distance was recorded as the voltage across the resonant circuit dropped below 10 mV. | |
| 4 | Sensitivity measured in accordance with Coilcraft application note Measuring Sensitivity of Transponder Coils. | |
| 5 | Matching capacitor value required for parallel resonant circuit operating at 125 kHz. | |
| 6 | DCR measured on micro-ohmmeter. | |
| 7 | SRF measured using Agilent/HP 8753D network analyzer. Details | |
| 8 | Ambient temperature range: | –40°C to +125°C |
| 9 | Storage temperature range: | Component: –40°C to +125°C T&R packaging: –40°C to +80°C |
| 10 | 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. | |
| 11 | Electrical specifications at 25°C. | |
| 12 | Temperature coefficient of inductance: +300 to +1100 ppm/°C. | |
