amorphous choke coils cat. no. e1008d the coils of the lying type are also provided for all the items listed in the table above. for a coil of the type, symbol e sho uld be added to the end of the part number shown in the table (e.g. bm05201x7e). the coils of the pedestal attachment type are also provided for the items with symbol @ in the table above. for a coil of the type, symbol d should be added to the end of the part number shown in the table (e.g. bm 05201x7d). the items preceded by symbol include two types, or the depth type with pedestal and the bed type with pedestal. to order th e item of the depth or bed type, add d or b at the end of the item of the item name respectively, as shown in the examples below:(bm05201x7d for the depth type with pedestal) (bm05201x7b for the bed type with pedestal) *order the auxiliary pins separately if they are required for the pedestal. *1 rated inductance tolerance : p 25%, the inductance at current 0[a] indicates the reference value. *2 the number of turns indicates the reference value. the specification of the inductance takes precedence over that of the num ber of turns. bm03421 b 6 bm05161 b 6 bm08600 b 6 bm10300 b 6 bm15150 b 6 bm20100 b 6 bm25060 b 6 bm30040 b 6 bm03551 b 7 bm05201 b 7 bm08800 b 7 bm10500 b 7 bm15270 b 7 bm20150 b 7 bm25090 b 7 bm30070 b 7 bm35050 b 7 bm40030 b 7 bm03801 b 8 bm05351 b 8 bm08121 b 8 bm10750 b 8 bm15350 b 8 bm20210 b 8 bm25130 b 8 bm30090 b 8 bm35070 b 8 bm40050 b 8 bm03122 b r bm05481 b r bm08191 b r bm10121 b r bm15570 b r bm20310 b r bm25200 b r bm30140 b r bm35100 b r bm40070 b r bm45050 b r 3 5 8 10 15 20 25 30 3 5 8 10 15 20 25 30 35 40 3 5 8 10 15 20 25 30 35 40 3 5 8 10 15 20 25 30 35 40 45 1100 360 140 62 35 23 13 7.6 1400 460 180 110 62 35 22 16 12 7.6 1800 840 280 170 84 52 33 23 20 12 2800 1100 460 280 140 74 51 33 23 15 11 420 160 60 30 15 10 6 3.6 550 200 80 50 27 15 9 7 5.0 3.4 800 350 120 75 35 21 13 9 7.5 5.0 1200 480 190 120 57 31 20 14 9.5 6.5 4.9 130 55 20 11 6 4 2 2 150 60 23 16 8 5 3 3 3 2 185 85 30 17 9 6 4 3 3 2 155 100 40 22 13 7 5 4 3 2 2 29.0 29.0 29.0 29.0 29.5 29.5 30.0 31.0 32.5 32.0 32.5 32.5 33.0 33.5 33.5 34.5 34.0 35.0 33.0 34.0 34.0 34.0 34.5 34.0 35.0 35.5 35.0 36.5 41.5 41.0 41.5 40.5 41.5 42.0 41.5 42.0 42.0 42.5 42.5 17.5 18.0 18.0 18.0 18.5 18.5 19.0 19.5 18.0 18.0 18.5 18.0 19.0 20.0 21.0 21.0 21.0 21.0 24.5 24.5 24.5 25.5 25.0 26.0 26.0 27.0 27.5 26.5 26.5 25.5 25.5 26.0 26.0 26.0 26.0 27.0 26.0 26.5 26.5 0.8 b 1p - 80t 1.0 b 1p - 48t 0.9 b 2p - 30t 1.0 b 2p - 20t 1.0 b 3p - 15t 1.0 b 4p - 12t 1.2 b 4p - 9t 1.3 b 4p - 7t 0.8 b 1p - 90t 1.0 b 1p - 54t 0.9 b 2p - 34t 1.0 b 2p - 27t 1.0 b 3p - 20t 1.2 b 3p - 15t 1.2 b 4p - 12t 1.3 b 4p - 10t 1.4 b 4p - 9t 1.4x5p - 7t 0.8 b 1p - 88t 1.0 b 1p - 60t 1.3 b 1p - 35t 1.1 b 2p - 27t 1.3 b 2p - 19t 1.2 b 3p - 15t 1.2 b 4p - 12t 1.3 b 4p - 10t 1.4 b 4p - 9t 1.4 b 5p - 7t 1.0 b 1p -100t 1.1 b 1p - 70t 1.3 b 1p - 45t 1.1 b 2p - 35t 1.3 b 2p - 25t 1.2 b 3p - 18t 1.2 b 4p - 15t 1.3 b 4p - 12t 1.4 b 4p - 10t 1.4 b 5p - 8t 1.3 b 6p - 7t p/n rated current a inductance (200khz) rating ( m h) 0[a] ( m h) *1 d.c.r. m o (max) winding mm fb lines-turns *2 outside dimension d (mm) w (mm) ? general specification ? major uses @ for switching mode power surpplies @ for dc-dc converter @ for normal mode line filter ? dc-current pre-loadability (1) ? dc-current pre-loadability (3) a d w (reference sample) l d : maximum outer diameter w : maximum width total lead length (l)* : 30mm (+3 mm, -3mm) soldering boundary (a)* : 1.5mmmax * the bottom of the core or coil ( )is defined as the base surface. @ core : b221310n, frequency : 200khz ? features @ miniaturization in comparison with tm series coils @ high inductance in low load current @ low leakage flux due to gap-less structure ? dc-current pre-loadability (2) @ core : b251510n, frequency : 200khz @ core : b251515n, frequency : 200khz ? dc-current pre-loadability (4) @ core : b322015n, frequency : 200khz (1/1)
