Electrical Con?guration Two inductors per unit;
internal terminals: #1(start) – #2(?nish) &
#4(start) – #3 (?nish).
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 speci?ed by suf?xing
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
Series Connected Speci?cations
Inductance Four (4) times parallel inductance speci?cations.
DCR Four (4) times parallel DCR speci?cations.
Rated DC Current minimum One-half of parallel Rated DC Current
speci?cations.
Packaging Tape & reel (24mm):
13" reel, 600 pieces max.; 7" reel not available
Weight (Grams) 1.0 (Ref.)
indicates the location of pin 1. Note: RoHS component
components will be marked with 4501R.
