YDPK0912-122K是YJYCOIN(益嘉源) 推出的一款插件式工字功率电感,针对中低功率电路的储能、滤波及噪声抑制需求设计,凭借紧凑尺寸、稳定参数及高性价比,广泛适配消费电子、工业控制等场景。
该电感属于工字功率电感范畴,区别于普通色环电感,其工字磁芯结构可实现更大电感量与更高饱和电流,适合功率传输场景;采用插件封装,安装方式灵活,支持手工焊接与自动化插件生产线;品牌端依托益嘉源的电感研发制造经验,产品参数一致性好,可满足批量应用的稳定性要求。
电感标称值为1.2mH(型号中“122K”代表12×10²μH=1200μH=1.2mH),精度±10%。该精度范围可覆盖大多数常规电路需求(如电源滤波、信号滤波),无需额外校准即可实现稳定功能,同时降低了生产端的筛选成本。
饱和电流为300mA,定义为电感电流达到该值时,电感值下降至初始值的30%(行业常规标准)。此参数直接决定了电感的最大负载能力:当电路工作电流不超过300mA时,电感值保持稳定,可有效避免因磁饱和导致的滤波效果下降、纹波增大等问题。
绕组直流电阻为2.3Ω,反映了电感的直流损耗特性。低DCR意味着在相同工作电流下,电感自身发热更少,能量转换效率更高,尤其适合对功耗敏感的场景(如小型便携设备),可降低电路整体温升。
常规工作频率覆盖20kHz~200kHz(工字电感典型范围),适配开关电源、LED驱动等低频功率电路,对高频噪声的抑制效果显著。
封装规格为D11×L15mm(直径11mm,长度15mm),尺寸紧凑,可节省PCB布局空间,适合小型化产品设计;工字磁芯结构采用高导磁率锰锌铁氧体材料,绕线均匀缠绕于磁芯柱,相比环形电感,工字结构更易批量生产,且电感值一致性更好。
采用插件式引脚,引脚材质为镀锡铜,抗氧化能力强,焊接时润湿性能好,可避免虚焊问题;引脚强度高,在振动环境下不易脱落,适合工业级或消费电子的常规应用场景。
该电感凭借参数适配性,可覆盖多领域应用:
YJYCOIN(益嘉源)作为国内电感制造厂商,YDPK0912-122K经过多道品质管控:
综上,YDPK0912-122K工字功率电感以平衡的参数设计、紧凑尺寸及高性价比,成为中低功率电路的理想选择,可满足多场景的储能、滤波及EMI抑制需求。
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.
