Windings have a 1:1 ratio and can be connected in series or parallel to create a wide range of inductance combinations. The secondary winding could be used as a feedback winding in switched mode power supplies. 49220 49330 49470 49680 49101 49151 49221 PACKAGE DETAILS Order Code TYP Weight (g) Packaging Style QTY 49XXX 4 Tape & Reel 500 MECHANICAL DIMENSIONS 0.47 (12.0) 2 0.47 (12.0) 1 3 4 Recommended Footprint Details PIN CONNECTIONS (TOP VIEW) 0.315 (8.0) MAX 1 2 4 3 All dimensions in inches (mm) 0.04 (1.0) 0.20 (5.0) 0.20 (5.0) 0.59 (15.0) 3 & 1 = Primary Winding 4 & 2 = Secondary Winding ABSOLUTE MAXIMUM RATINGS Operating free air temperature range Storage temperature range C&D Technologies (NCL) Ltd Tanners Drive, Blakelands North Milton Keynes MK14 5BU, England Tel: +44 (0)1908 615232 Fax: +44 (0)1908 617545 email: info@cdtechno-ncl.com C&D Technologies Inc. 3400 E Britannia Drive, Tucson, Arizona 85706, USA Tel: +1 (800) 547-2537 Fax: +1 (520) 741-4598 email: sales@cdtechno.com -40C to 85C -40C to 125C C&D Technologies (NCL) Limited reserve the right to alter or improve the specification, internal design or manufacturing process at any time, without notice.
