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.
