When ordering, please specify **termination** code: **RFB1010-183L** - **Termination: L** = Tin-silver over tin over copper over steel. **Special order** : **T** = RoHS tin-silver-copper (95.5/4/0.5) or **S** = non-RoHS tin-lead (63/37). 2. Inductance tested at 100 kHz, 0.1 Vrms, 0 Adc on an Agilent/HP 4284A LCR-meter or equivalent. 3. SRF measured using Agilent/HP 4191A or equivalent. 4. DC current at which the inductance drops 10% (typ) from its value without current. ## **Typical L vs Current** **==> picture [206 x 225] intentionally omitted <==** **----- Start of picture text -----**
