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.
