When ordering, please specify **lead length** and **termination** codes: **RFC1010B-183E** **Lead length: A** = 3.6 mm ±0.3 mm (special order) **B** = 5.0 mm ±0.5 mm **C** = 7.0 mm ±0.5 mm (special order) **D** = 8.0 mm ±0.5 mm (special order) **E** = 10.0 mm ±1.0 mm (special order) **Termination: E** = RoHS compliant tin-silver over tin over copper over steel. Special order: **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 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. **==> picture [117 x 44] intentionally omitted <==** Document 1125-2 Revised 01/30/14 © Coilcraft Inc. 2014 This product may not be used in medical or high risk applications without prior Coilcraft approval.
