CST Series CST063, 103, 104, 126 Types
Transformers
For Power Supply
SMD
FEATURES
• Separation of wire winding terminals from soldering terminals
entirely eliminates problems such as pin lifting(during mounting)
and wire breakage(0.1mm max. coplanarity).
• This series is compatible with automatic mounting equipment
utilizing image recognition or boss positioning.
• Embossed carrying tape packaging is standard.

Tape width(mm)
• TDK’s unique core design technology has resulted in enhanced
miniaturization; the CST063 type has a typical height of only
2.7mm with a mass of 0.3g.

• A highly efficient magnetic circuit design has been employed,
enabling it to be used for 1MHz applications with power require-
ments of up to 1W(CST063), 3W(CST103 and CST104) and
9W(CST126).
• Compatible with reflow soldering.
