YSPI1050-2R2M是益嘉源(YJYCOIN)推出的中功率一体成型贴片电感,针对DC-DC电源转换、车载电子、工业控制等场景设计,平衡了电感值精度、电流承载能力与功率损耗,是替代传统绕线电感的高可靠性方案。
电感值标称2.2μH,精度±20%,覆盖工业级应用对电感参数的基本要求(无需更高精度时可降低成本)。电感值随频率变化小,适合10kHz~2MHz的开关电源频率范围,满足多数中功率电源的滤波与储能需求。
额定电流10A(连续工作电流),在额定温度(25℃~85℃)下,电感值变化不超过±5%(行业常规标准),可稳定支撑中功率电源的电流输出,避免因电流过载导致的电感饱和失效。
直流电阻(DCR)仅6.6mΩ,属于同类产品中的低损耗水平——以10A连续电流为例,单电感功率损耗仅I²R=10²×6.6e-3=0.66W,显著减少发热,提升电源转换效率(可降低1%~1.5%效率损耗)。
工作温度范围覆盖-40℃~+85℃(益嘉源工业级标准),符合车载电子、户外工业设备的环境要求;一体成型结构无磁芯松动风险,抗振动(10G~20G)、抗冲击性能优于传统绕线电感。
采用SMD贴片封装,无引线设计,适合自动化贴片机高速贴装,生产效率高;同时节省PCB空间,便于高密度电源模块布局。
YSPI1050-2R2M针对中功率电源场景优化,核心应用包括:
PLC可编程控制器的开关电源、伺服电机驱动电源(10A以内电流输出)
户外LED显示屏、大功率LED路灯的恒流驱动电源(支撑10A以内负载电流)
6.6mΩ的DCR远低于同类绕线电感(通常10mΩ以上),可将电源转换效率提升0.5%~1.2%,尤其适合对效率敏感的快充、车载电源场景。
一体成型结构避免磁芯开裂、线圈松动问题,抗振动(10G~20G)、抗冲击性能符合IEC 60068标准,适合车载、工业等严苛环境。
±20%的精度满足多数中功率应用需求,相比高精度电感(±10%以内)成本降低15%~20%,性价比突出。
SMD封装尺寸与行业标准匹配,可兼容主流贴片机,贴装良率达99.5%以上,适合大规模量产。
益嘉源(YJYCOIN)是国内专注电感研发生产的厂商,产品通过RoHS、REACH环保认证,所有电感均经过100%全检+老化测试(测试电感值、DCR、绝缘电阻),提供1年以上质保,可满足工业级、车规级(需定制)的可靠性要求。
该产品通过对电感性能与成本的精准控制,成为中功率电源领域的高性价比选择,可有效降低终端产品的功耗与设计复杂度。

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.
