YNR8040-680M是益嘉源(YJYCOIN)推出的一款磁胶屏蔽贴片功率电感,型号中:
作为小功率电源电路的核心储能/滤波元件,它兼顾了电磁屏蔽性、小体积与成本优势,适用于消费电子、工业控制等对EMI(电磁干扰)敏感的场景,是替代传统非屏蔽电感的实用选择。
电感值为68μH±20%,实际范围在54.4μH~81.6μH之间,满足多数常规DC-DC转换电路的储能需求。20%精度属于功率电感的商用级标准,平衡了性能与量产成本,无需额外校准即可稳定工作。
额定电流1.25A,指电感在-40℃~85℃工作温度下,电感值下降不超过30%的最大连续电流。若电流超过此值,磁芯会进入饱和状态,储能能力大幅下降,可能导致电路输出电压波动、元件发热加剧。
DCR为196mΩ,是电感绕组的直流电阻,直接影响导通损耗(损耗=I²×R)。196mΩ的阻值在同规格电感中处于中等偏优水平,能有效降低工作时的发热,提升电源转换效率(约提升2%~3%,相比同电流下250mΩ的电感)。
采用高磁导率铁氧体磁芯+磁胶密封,磁芯一致性好,饱和磁通密度高;磁胶无金属杂质,避免了屏蔽壳与磁芯的涡流损耗,进一步提升效率。
绕组采用0.2mm漆包线多层绕制,匝数均匀,减少分布电容(约2pF),适合高频(100kHz~1MHz)电源电路的滤波需求。
产品通过-40℃~85℃温循测试(1000次)、240小时湿热测试(85℃/85%RH),引脚焊接强度≥5N,满足工业级与消费级产品的可靠性要求。
若需更高电流(如2A),可选择同系列YNR8040-680M高电流版(DCR约220mΩ,额定电流2A);若需更小封装(6×6mm),可考虑益嘉源YNR6030-680M;若对精度要求更高(±10%),需切换至“K”档精度的对应型号(如YNR8040-680K)。
YNR8040-680M凭借磁胶屏蔽、小体积与可靠性能,成为小功率电源电路的高性价比选择,广泛适配消费电子、工业控制等多领域应用。
Request for quote
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.
