SMT power inductors are formed by directly connected
ferrite electrode with magnetic shielding.
• T : Packing : Tape and Reel
• HP : Low DCR
• LD : High Power
• Tolerance : K= 10% ; M= 20% ; T= 30%
• CEC Internal No.: B: Silver plated terminals (3D12~6D38);
S: Base type terminals (2D11~2D18HP & 62T&127)
•Note : YAGEO will start to release SCD Series inductor
with lead-free terminals that meet SONY SS-
00259’s criterial for lead-free product in Q2 of 2004,
and YAGEO Internal No will changed to “N” as
identification.

• Test Freq.(L): SCDS62: 3.3 ~ 8.2 H(7.96MHz/1V), 10~82 H(2.52MHz/1V), 100 ~ 330 H(1KHz/1V)
SCDS64/73/74/125/127: (1KHz/1V)
• Other type Rated current : The rate current indicastes the current when the inductance decreases to 65%. Over of it's nominal
value or D.C.current when the temperature rising t =40ºC lower, whichever is lower.
