CBW160808U121T 为风华(FH)出品的一款贴片磁珠,封装为0603(公制1608),单通道设计,主要用于抑制中高频电磁干扰(EMI)。规格上在100MHz时阻抗为120Ω,阻抗公差±25%;工作温度范围为-55℃至+125℃,适应一般商用与工业环境。
该磁珠在中高频区具有显著阻抗,能有效抑制100MHz左右的共模/差模干扰。DCR较低(约0.14Ω量级),对直流压降影响小,但在接近额定电流时仍需关注温升与压降。阻抗随频率变化,应参考厂家阻抗曲线选择匹配目标噪声频段。
长时间大电流工作会造成自热,建议在实际应用中按额定电流做适当降额(例如留10–20%裕量),并注意周围散热条件。封装适合常规回流焊工艺,焊接温度和时长应遵循风华推荐回流曲线以保证可靠性。
CBW160808U121T 在0603封装下提供了在100MHz附近较高阻抗的EMI抑制能力,适用于对中高频噪声有明确抑制需求且电流需求在1A~1.3A量级的场景。选型时建议结合实际频谱、温升测试与回流工艺验证,以确保长期可靠工作。

Product sourcing intelligence
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
Typical RFQ scenarios based on the WMSIC form fields, catalog data, manual review steps, and shipment preparation workflow.
The buyer shares the full part number, package requirement, quantity, destination, and available product photos so the quotation can record the exact version under review.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
