1. When ordering, please specify lead length and termination codes:
RFC0810B-183KE
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)
F =25.0 mm ±1.0 mm, packaged in fanfold tape, 800 parts per box (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.
