1. Specify tolerance, termination and packaging codes:
DO5022P-105MLD
Tolerance: M = 20%, K = 10% (Table shows stock
tolerances in bold.)
Termination: L = RoHS compliant gold over nickel over
phos bronze.
Special order:
T = RoHS tin-silver-copper (95.5/4/0.5)
or S = non-RoHS tin-lead (63/37).
Packaging: D = 13″ machine-ready reel. EIA-481
embossed plastic tape (250 parts per
full reel).
B = Less than full reel. In tape, but not
machine ready.
To have a leader and trailer added
($25 charge), use code letter D
instead.
2. Inductance tested at 100 kHz, 0.1 Vrms, 0 Adc using an
Agilent/HP 4263B LCR meter or equivalent.
3. Tolerances in bold are stocked for immediate shipment.
4. SRF >13 MHz measured using Agilent/HP 8753D
network analyzer; <13 MHz using Agilent/HP 4192A.
5. DC current at which inductance drops the specified
amount from its value without current.
6. Current that causes a 40°C temperature rise from 25°C
ambient.
7. Electrical specifications at 25°C.
Refer to Doc 362 “Soldering Surface Mount Components”
before soldering.
