Tolerance: K = 10%. Electrical specifications at 25C. Operating temperature: -40C to +125C. L measured with HP 4284A LCR meter. SRF measured with HP 4291B or HP 8753E. DCR measured with 502BC milli-OHM meter. Read distance measured with KEELOQ Transponder Evaluation Kit part number DM303005 from Microchip. Distance was record as the voltage across the resonant circuit dropped below 10mV. 8. Sensitivity measured in accordance with Frontier Electronics Corp. application note "Measuring Sensitivity of Transponder Coils" 9. Matching capacitor vale required for parallel resonant circuit operating at 125 KHz. Note: RoHS compliant; for the RoHS parts, we add "-LFR" at the end of the P/N.
