TAI-TECH台庆HCB3216KF-101T30属于0805(3216)封装片式高频功率电感,主打「低直流电阻+宽温范围+高频阻抗稳定」三大核心优势,专为需兼顾功率承载与高频性能的电子电路设计。其典型应用场景包括:
标称阻抗100Ω@100MHz,误差±25%——在100MHz频段阻抗一致性良好,可有效抑制高频噪声,避免信号反射损耗,适合射频电路匹配与滤波。
典型值40mΩ——低DCR是功率电感核心优势:3A连续电流下功耗仅为(I^2R=3^2×0.04=0.36W),显著降低发热,提升电源转换效率(如快充模块效率可提升1%~2%)。
连续工作电流3A——满足多数消费电子与工业电源的中等功率需求;若需峰值电流,可参考台庆原厂饱和电流参数(一般高于额定电流,如5A左右)。
-40℃~+125℃——符合工业级与车规级(部分)环境要求,低温(北方户外设备)与高温(车载仪表盘)场景下性能衰减极小(台庆测试数据:125℃时DCR变化<10%)。
公制3216(对应英制0805),具体尺寸:(3.2mm×1.6mm×1.2mm)(长×宽×高)——体积紧凑,支持自动化贴装(SMT),适配高密度PCB布局。
表面贴装(SMD),两端电极设计——焊接可靠性强,与常规0805封装元件兼容,无需特殊焊接工艺。
铁氧体磁芯+粗铜线绕制:铁氧体磁芯保证高频阻抗稳定,粗铜线降低DCR同时提升电流承载,磁芯经宽温处理,适配-40~125℃环境。
-40~125℃范围内,DCR变化率<10%,阻抗变化率<15%,满足长期恶劣环境运行需求。
符合JESD22-A101标准(无加速湿度试验):85℃/85%RH环境下放置1000小时,性能无明显衰减。
通过振动试验(10~2000Hz,1.5g加速度)与冲击试验(100g,11ms),适合移动设备或工业振动场景。
符合IEC 61000-4-2标准(接触放电8kV,空气放电15kV),但实际应用仍建议采用ESD防护(如接地、防静电包装)。
额定电流3A为连续值,建议实际电流不超过2.4A(留20%余量),避免磁芯饱和或发热超标。
采用回流焊,温度曲线需满足:
PCB设计时增大电感焊盘面积(+10%~20%),或布置散热过孔,降低工作温度。
100Ω阻抗针对100MHz优化,若应用于其他频率(如50MHz/200MHz),需重新测试阻抗特性。
未焊接元件存储于干燥环境(湿度<60%)、15~35℃,运输避免剧烈振动与静电损伤。
该产品凭借紧凑体积、低损耗与宽温特性,成为消费电子、工业控制与射频领域的高性价比选择,可有效提升电路效率与可靠性。
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.
