1. When ordering, please specify

termination code:

RFS1113-105ME

Termination: E = 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 equilvalent.

4. DC current that causes the specified inductance drop from its value without current..

5. Current that causes the specified temperature rise from 25°C ambient.

6. Electrical specifications at 25°C.
