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.
Example: 4501-102
