1 When ordering, please specify termination and packaging codes: e.g. 4513TC-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 (2500 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 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 at 25°C on a micro-ohmmeter. For other operating temperatures, use this DCR at Temperature calculator.use this DCR at Temperature calculator.
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
Tape and reel 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: +50 to +210 ppm/°C.
Refer to Application Notes Transponder Coils in an RFID System and Measuring Sensitivity of Transponder Coils for additional information.
Refer to Soldering Coilcraft Components before soldering.
PCB washing: Tested to MIL-STD-202 Method 215 plus an additional aqueous wash. More info.
