MWSD1608FE220KT是顺络电子(Sunlord)MWSD系列中的小型化绕线片式功率电感,针对便携电子、物联网终端等对尺寸、功耗敏感的场景设计。顺络作为国内电感行业龙头,该系列产品兼顾电气性能与紧凑封装,是中低端消费电子、工业小型电路的高性价比选择。
标称电感值为22μH,精度±10%(实际范围19.8μH~24.2μH)。该精度覆盖绝大多数普通电路的设计需求,既保证批量生产的一致性,又无需额外高精度筛选成本,适合对电感量要求不苛刻的电源、滤波电路。
连续工作额定电流为200mA,指在规定温度下(通常25℃),电感允许的最大连续直流电流——此时电感温升不超过安全阈值(行业标准≤40℃)。该规格适配小功率电源(如5V转3.3V/1.8V的DC-DC降压模块)的储能需求。
线圈本身的直流电阻为2.8Ω,低DCR直接降低工作损耗:在200mA电流下,损耗仅为0.112W(I²R公式),有助于提升电路效率,尤其适合便携设备的低功耗设计。
采用绕线片式结构,相比叠层片式电感,绕线设计具有更高Q值(品质因数)和更低交流损耗,在高频(100kHz~1MHz)应用中性能更优,同时支持相同封装下更大的电流承载能力。
采用0603英制封装(对应公制1608),典型尺寸为:
紧凑尺寸适配高密度PCB布局,满足智能手环、蓝牙耳机等小型设备的空间限制。
外壳采用耐高温树脂材料,可承受回流焊温度(符合IPC/J-STD-020标准),同时具备良好的机械强度和耐候性,能应对振动、冲击等环境挑战。
顺络对该产品实施全流程质量管控:
MWSD1608FE220KT凭借“小尺寸+低损耗+高可靠性”的组合优势,成为小型化电子设备的主流功率电感选择之一。

Use the form for single models, category sourcing, and multi-line BOM requirements.
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.
