1008 Size	Standard GLU		Molded Bobbin Wound:
2.5 x 2.0 x 1.6 mm	Features:	0.22 to 100.0 �H	Coil is wound on a ferrite bobbin which is molded in epoxy with its axis normal to the mounting surface. This model is a smaller version of the standard GLA series, up to 100 �H. The tradeoff for the smaller size is lower rated current and higher DCR.
0.098 x 0.079 x 0.063"	Epoxy encapsulation

	Nonmagnetic GLU		Molded Bobbin Wound:
	Features:	0.010 to 0.82 �H	Coil is wound on a plastic bobbin which is molded in epoxy with its axis normal to the mounting surface. The nonmagnetic version has lower inductance and Q than standard FLU series with tighter inductance tolerance. For a given value, DKr is higher for nonmagnetic types, since ferrite core in the standard series makes for higher inductance for a given number of turns.
	Lower inductance
	Tighter tolerance
	High frequency
	Epoxy encapsulated
	Superior temperature stability

	Shielded High Current GLW		Molded Bobbin Wound:
	Features:	1.0 to 33.0 �H	Coil is wound on a ferrite bobbin which is molded in ferrite filled epoxy with its axis normal to the mounting surface. Ferrite filler in epoxy encapsulation reduces external magnetic coupling. Units can be more closely spaced than with standard GLU series.
	Higher Current
	Lower DCR
	Ferrite filled encapsulation
	Can be closely spaced

1210 Size	Standard GLA		Molded Bobbin Wound:
3.2 x 2.5 x 2.2 mm	Features:	0.22 to 220.0 �H	Coil is wound on a ferrite bobbin which is molded in epoxy with its axis normal to the mounting surface.
0.126 x 0.098 x 0.087"	Standard size
	Epoxy encapsulated

	Nonmagnetic GLA		Molded Bobbin Wound:
	Features:	0.047 to 8.2 �H	Coil is wound on a plastic bobbin which is molded in epoxy with its axis normal to the mounting surface. The nonmagnetic version has lower inductance and Q than standard GLA series, and inductance tolerance is tighter. For a given value, DCR is higher for nonmagnetic types, since ferrite core in the standard series makes for higher inductance for a given number of turns.
	Lower inductance
	Tighter tolerance
	High frequency
	Epoxy encapsulated
	Superior temperature stability


	Shielded GLC		Molded Bobbin Wound:
	Features:	10.0 to 270.0 �H	Coil is wound on a ferrite bobbin which is molded in ferrite filled epoxy with its axis normal to the mounting surface. Ferrite filler in epoxy encapsulation reduces external magnetic coupling. Units can be more closely spaced than with standard GLA series, but rated current is lower.
	Ferrite filled encapsulation
	Can be closely spaced


	Shielded GLAC		Molded Bobbin Wound:
	Features:	1.0 to 330.0 �H	Coil is wound on a ferrite bobbin which is molded in ferrite filled epoxy with its axis normal to the mounting surface. Ferrite filler in epoxy encapsulation reduces external magnetic coupling. Units can be more closely spaced than with standard GLA series. Series has the lowest DCR for 1210 size, and higher current rating than GLA and GLC models.
	Lowest DCR
	High Current
	Ferrite filled encapsulation
	Can be closely spaced

1210 Size	Shielded High Current GLD		Molded Bobbin Wound:
3.2 x 2.5 x 2.2 mm	Features:	1.0 to 330.0 �H	Coil is wound on a ferrite bobbin which is molded in ferrite filled epoxy with its axis normal to the mounting surface. Ferrite filler in epoxy encapsulation reduces external magnetic coupling. Units can be more closely spaced than with standard GLA series, but rated current is lower. Highest current rating for 1210 size.
0.126 x 0.098 x 0.087"	Highest Rated Current
	Low DCR
	Ferrite filled encapsulation
	Can be closely spaced

1812 Size	GLB		Molded Bobbin Wound:
4.5 x 3.2 x 3.2 mm	Features:	0.22 to 1000.0 �H	Coil is wound on a ferrite bobbin which is molded in epoxy with its axis normal to the mounting surface. GLB models are the largest of the SURFCOIL models and offer the highest inductance values and high rated current; Q is superior to comparable values in the GLD series.
0.177 x 0.126 x 0.126"	Highest inductance values
	High rated current
	High Q
	Epoxy encapsulated

	Shielded GLBP		Molded Bobbin Wound:
	Features:	10.0 to 220.0 �H	Coil is wound on a ferrite bobbin which is molded in ferrite filled epoxy with its axis normal to the mounting surface. GLBP models offer higher rated current than the standard GLB series, and can be more closely spaced.
