NOTES:
1. Temperature rise is 55°C in typical buck or boost circuits operating
at 300kHz with rated Idc current and reference ET applied to inductor.
2. Total inductor loss is 1.8W for 55°C temperature rise above ambient.
3. In high volt-time applications, additional heating in the component
can occur due to core losses in the inductor which may necessitate
derating the current in order to limit the temperature rise of the
component. In order to determine the approximate total losses
(or temperature rise) for a given application, both copper and core
losses should be taken into account.
Estimated Temperature Rise:
Trise = K3 * (Coreloss(W) + Copperloss(W)
.833

4. Optional Tape & Reel packaging can be ordered by adding a "T"
suffix to the part number (i.e. PL8304 becomes PL8304T). Pulse
complies to industry standard tape and reel specification EIA481.

美国“封杀”华为的事情还没有平息，美国国土安全部又来凑热闹了。美国国土安全部发布“中国制造的无人机可能正在向中国制造商发送敏感飞行数据，政府可以访问这些数据”的警告，意在指控大疆无人机可能会对美国安全造成威胁。就此，大疆官方作出了迅速回应，称：“我们技术的安全性已经在全球得到反复验证，其中也包括美国政府和美国领先企业的独立验证”。 大疆御Mavic Air “无中生有”是美国政府惯用伎...[详细]
