|1||When ordering, please specify termination and packaging codes: e.g. KA4947-AEC|
E = Halogen free component. RoHS compliant silver-palladium-platinum-glass frit terminations.
Special order, added cost: T = RoHS tin-silver-copper (95.5/4/0.5) or
S = non-RoHS tin-lead (63/37).
|Packaging:||C = 7"
EIA-481 embossed plastic tape 250 parts per full reel).
B = Less than full reel
In tape, but not machine-ready. To have a leader and trailer added ($25 charge), use code letter C instead.
D = 13" machine-ready reel
EIA-481 embossed plastic tape. Factory order only, not stocked (1000 parts per full reel).
|2||Inductance is measured at 100 kHz, 0.1 Vrms, 0 Adc on an Agilent/HP 4284A LCR meter or equivalent.|
|3||DCR measured at 25°C on a micro-ohmmeter. For other operating temperatures, use this DCR at Temperature calculator.|
|4||Ipk: Peak primary current drawn at minimum input voltage.|
|5||Ambient temperature range:||−40°C to +85°C with Ipk current.|
|6||Storage temperature range:||Component: −40°C to +125°C
Tape and reel packaging: −40°C to +80°C
|7||Maximum part temperature: +125°C (Ambient + temperature rise)|
|8||Resistance to soldering heat: Three reflows at >217°C for 90 seconds (+260°C ±5°C for 20 – 40 seconds), allowing parts to cool to room temperature between.|
|9||Electrical specifications at 25°C.|
|Refer to Soldering Coilcraft Components before soldering.|
