1. the temperature of the component (ambient plus temperature rise) must be within the stated operating temperature range. 2. the above transformers and inductors have been tested and approved by pulse's power ic partners and are sited in the appropriate datasheet or evaluation board documentation at these companies. to determine which ic and ic partners are matched with the above pulse part num- bers please consult the ic cross reference on the pulse website. 3. for flyback topology applications, it is necessary to ensure that the trans- former will not saturate in the application. the peak flux density (bpk) should remain below 2700gauss. to calculate the peak flux density use the following formula: bpk (gauss) = k1_factor * ipk(a) 4. in high volt-sec applications, it is important to calculate the core loss of the transformer. approximate transformer core loss can be calculated as: coreloss (w) = 1.32e-13 * (freq_khz) 1.63 * ( b_gauss) 2.63 where b can be calculated as: for flyback topology: b = k1_factor * (a) for forward topology: b = k1_factor * volt-sec 5. optional tape & reel packaging can be ordered by adding a " t " suffix to the part number (i.e. pa0273nl becomes pa0273nl t ). pulse complies with industry standard tape and reel specification eia481. the tape and reel for this product has a width (w=44mm), pitch (po=32mm) and depth (ko=11.78mm). 6. the " nl " suffix indicates an rohs-compliant part number. non-nl suf- fixed parts are not necessarily rohs compliant, but are electrically and mechanically equivalent to nl versions. if a part number does not have the " nl " suffix, but an rohs compliant version is required, please con- tact pulse for availability. notes www.pulseeng.com 6 preliminary p666.a (3/08) this is a ?preliminary? product data sheet. products mentioned on this data sheet are in development and in the process of bein g qualified. these products are not fully released nor are they in production. features, specifications and performance of products offered are subject to change without notice. other brand and product names mentioned herein may be products and/or registered trademarks of their respective owners. for current information on this produ ct, please contact the pulse office nearest you and ask for the ?power applications engineer.? ? copyright, 2008. pulse engineering, inc. all rights reserved. for more information: pulse worldwide headquarters 12220 world trade dr. san diego, ca 92128 u.s.a. www.pulseeng.com tel: 858 674 8100 fax: 858 674 8262 pulse south asia 150 kampong ampat #07-01/02 ka centre singapore 368324 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. 32667 tel: 886 3 4643715 fax: 886 3 4641911 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 pulse north china room 1503 xinyin building no. 888 yishan rd. shanghai 200233 china tel: 86 21 32181071 fax: 86 21 32181396 pulse european headquarters einsteinstrasse 1 d-71083 herrenberg germany tel: 49 7032 7806 0 fax: 49 7032 7806 12
