Tiny Power Inductors Achieve Impressive DC Characteristics

Said to be more compact than conventional power inductors, the 5 mm x 5 mm x 2 mm NRS5020 and 5 mm x 5 mm x 4 mm NR5040 wire-wound power inductors claim to offer the industry’s best dc-bias characteristics. The 4.7-mH NRS5020 specifies a dc-current rating of 2A and a dc resistance of 60 mΩ. At 10 µH, the NR5040 features a higher rated current of 2.3A. Sample price for either the NRS5020 or NR5040 is $0.30 each. TAIYO YUDEN INC., Schaumburg, IL. (800) 348-2496.
