Specify termination and packaging codes: MSS7341-224MLD Termination: L = RoHS compliant matte tin over nickel over phos bronze (current production) or gold over nickel over phos bronze (prior production) Special order: T = RoHS tin-silver-copper (95.5/4/0.5) over gold over nickel over phos bronze or S = non-RoHS tin-lead (63/37) over gold over nickel over phos bronze. Packaging: D = 13″ machine-ready reel. EIA‑481 embossed plastic tape (1200 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 measured at 100 kHz, 0.1 Vrms, 0 Adc using a Coilcraft SMD‑A fixture in an Agilent/HP 4263B LCR meter. 3. SRF measured using an Agilent/HP 8753D network analyzer and a Coilcraft SMD‑D test fixture. 4. DC current at which the inductance drops the specified amount from its value without current. 5. Current that causes the specified temperature rise from 25°C ambient. 6. Electrical specifications at 25°C. Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
