F 0.025 ± 0.010 0.64 ± 0.25
G 0.040 (Ref.) 1.02 (Ref.)
Electrical Configuration Two inductors per unit;
internal terminals: #1(start) – #2(finish) &
#4(start) – #3 (finish).
Series Externally connect #2 to #4.
Parallel Externally connect #1 to # 4 and # 2 to # 3.
Operating Temperature Range –55°C to +125°C
Rated DC Current Based upon 20°C temperature rise
from 25°C ambient.
Maximum Power Dissipation at 25°C 0.230 Watts
Inductance Tolerance Tolerance is specified by suffixing
an alpha character to the part number as follows: K = 10%,
L = 15%. M = 20%. Units are normally supplied to the
tolerance indicated in the tables.
Marking Delevan; inductance and tolerance. A white dot
indicates the location of pin 1. Note: RoHS component
components will be marked with 4501R.
