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
0.313 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.
Example: 4448-102M

Weight (Grams) 2.5 (Ref.)
Inductance at Rated DC Current
Minimum percent of
measured zero Amp DC Inductance.
-02M to -34L = 60%; -102M to134L = 50%
Packaging
