smt power inductors round wire coils - pg0702nl series notes from tables 1. actual temperature of the component during system opera - tion (ambient plus temperature rise) must be within the standard operating range. 2. inductance at irated is a typical inductance value for the component taken at rated current. 3. the rated current as listed is either the saturation current (@ 25c) or the heating current depending on which value is lower. 4. the dcr of the part is measured at an ambient temperature of 20c 3c from point a and b as shown above on the mechanical drawing. 5. the saturation current, isat, is the current at which the component inductance drops by 20% (typical) at an ambient temperature of 25c. this current is determined by placing the component in the specified ambient environment and applying a short duration pulse current (to eliminate self-heating effect) to the component. 6. the heating current, idc, is the dc current required to raise the component temperature by approximately 40c. the heating current is determined by mounting the component on a typi - cal pcb and applying current for 30 minutes. the temperature is measured by placing the thermocouple in the coil of the unit under test. take note that the components performance varies depending on the system condition. it is suggested that the component be tested at the system level, to verify the temperature rise of the component during system operation. 7. core loss approximation is based on published core data: core loss = k1 * (f) 1.12 * (k2 d i) 2.17 where: core loss = in watts k1 = 2.20e-11 f = switching frequency in khz k1 & k2 = core loss factors d i = delta i across the component in ampere k2 d i = one half of the peak to peak flux density across the component in gauss 8. unless otherwise specified, all testing is made at 100khz, 0.1v ac . 9. optional tape & reel packaging can be ordered by adding a t suffix to the part number (i.e. pg0702.401nl becomes pg0702.401nlt). pulse complies to industry standard tape and reel specification eia481. the tape and reel for this product has a width(w=24.0mm), pitch(po=16.0mm) and depth (ko=8.9 mm). typical inductance vs current characteristics @ 25c and 100c 0. 0 1. 0 2. 0 3. 0 4. 0 5. 0 6. 0 7. 0 0.00 5.00 10.00 15.00 20.00 25.00 30.00 i ndu ct anc e (u h) .6 82 nl @ 100 c . 472n l @ 100 c . 302n l @ 100 c . 222n l @ 100 c . 102n l @ 100 c .6 82 nl @ 25 c . 472 nl @ 25 c . 222 nl @ 25 c . 302 nl @ 25 c . 102 nl @ 25 c 0. 0 0. 1 0. 2 0. 3 0. 4 0. 5 0. 6 0. 7 0 1 0 2 0 3 0 4 0 5 0 dc bi as (a ) in du ct an ce (u h) .6 01n l @ 25 c . 451n l @ 25 c . 401n l @ 25 c . 301n l @ 25 c .6 01n l @ 100 c . 451n l @ 100 c . 401n l @ 100 c . 301n l @ 100 c dc bi as (a ) www.pulseeng.com 2 p667.d (8/09) pulse worldwide headquarters 12220 world trade dr. san diego, ca 92128 u.s.a. www.pulseeng.co m tel: 858 674 8100 fax: 858 674 8262 pulse south asia 135 joo seng rd. #03-02 pm industrial bldg. singapore 368363 tel: 65 6287 8998 fax: 65 6280 0080 pulse north asia no. 26, kao ching rd. yang mei chen taoyuan hsien taiwan r. o. c. tel: 886 3 4643715 fax: 886 3 4641911 pulse north china room 1503 xinyin building no. 888 yishan rd. shanghai 200233 china tel: 86 21 54643211/2 fax: 86 21 54643210 pulse europe einsteinstrasse 1 d-71083 herrenberg germany tel: 49 7032 7806 0 fax: 49 7032 7806 135 performance warranty of products offered on this data sheet is limited to the parameters specified. data is subject to change without notice. other brand and product names mentioned herein may be trademarks or registered trademarks of their respective owners. ? copyright, 2009. pulse engineering, inc. all rights reserved. pulse china headquarters b402, shenzhen academy of aerospace technology bldg. 10th kejinan rd. high-tech zone nanshan district shenzen, pr china 518057 tel: 86 755 33966678 fax: 86 755 33966700 for more information:
