E CORE FOR SMD

• Low profile and suitable for surface mounting.
• High accuracy in B, F and H dimension because coil inserting part(ditch) is made by grinding.
• Please contact our sales office about each dimension and shape.

	±Tolerance(mm)
B	≤0.05
F	≤0.05
H	≤0.05

DRUM CORE

• For Mn-Zn materials, performance at DC is excellent.
• Both small and thin types are available.
• Please contact our sales office about each dimension.
• If necessary, insulation coating is available.

2.5 ≤ A ≤10 2.0 ≤ B ≤ 10 2 ≤ C ≤ 6 0.4 ≤ D ≤ 3 0.5 ≤ E ≤ 7

LONG LENGTH AND THIN THICKNESS E CORE

• Suitable for low profile coil.
• Characteristics and strength depend on A, B and C1 dimension and please contact our sales office.

Dimension(mm)
9 ≤ A ≤ 16
9 ≤ B ≤ 20
C1 ≤ 3.0
C2 ≤ 1.0

BAR CORE

• Small diameter and long length using pressing out technique.
• Suitable for antenna.

1.0 ≤ ø d ≤ 3.0 L ≤ 5.0

INSULATION COATED RING CORE

• Excellent for high voltage resistance and prevent from peeling off when winding.
• Small and thin type balun core and E core are available.
• Please contact our sales office about each dimension.

Outer diameter ≤ ø 8mm

Coating: Select parylene or fluorine. Thickness of coating: 10 ~ 40m

SLICED CORE

• Thin and board type core using slicing and grinding technique.
• Suitable for antenna and I core using with E core.
