YNR2512-3R3M是益嘉源(YJYCOIN)针对小型化、低功耗电子设备优化的磁胶屏蔽功率电感,核心聚焦“高密度布线适配、低损耗发热、抗电磁干扰”三大需求,适配主流贴片自动化生产,是便携电子、物联网节点等场景的电源设计优选。
标称电感值3.3μH,精度±20%,覆盖5V→3.3V、3.7V→1.8V等常见DC-DC降压拓扑的电感量需求。宽精度范围降低了设计对电感一致性的苛刻要求,同时提升供应链选型灵活性(无需过度依赖同批次一致性)。
额定电流1.04A(环境温度25℃下,电感自身温升≤40℃的最大连续电流),精准匹配小型设备典型负载:
203mΩ的低DCR是核心亮点:铜损与电流平方成正比((P=I^2R)),1A负载下铜损仅约0.2W,比同封装普通电感(DCR≥300mΩ)低30%以上,可直接提升DC-DC转换效率1%-2%,显著降低电源模块发热。
采用磁胶屏蔽结构,相比非屏蔽电感,电磁辐射(EMI)降低10-15dB,有效减少对周围射频电路(WiFi、蓝牙)的干扰,符合便携设备对电磁兼容性(EMC)的严格要求(如智能手机射频频段的干扰抑制)。
SMD贴片封装,公制尺寸2.5×2.0×1.2mm,尺寸紧凑(仅相当于指甲盖1/10大小),适配高密度布线的小型设备:
YNR2512-3R3M通过“小封装+低损耗+屏蔽”的组合优势,精准命中小型电子设备的电源设计痛点,是替代传统插件电感或非屏蔽电感的高性价比方案。

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.
