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 25°C that causes the specified inductance drop from its value without current.
Click for temperature derating information.
5. Current that causes the specified temperature rise from 25°C ambient. This information is for reference
only and does not represent absolute maximum ratings.
Click for temperature derating information.
6. Electrical specifications at 25°C.
