CB2012T101K 产品概述
一、产品简介
CB2012T101K 是 TAIYO YUDEN（太诱）推出的一款功率电感，规格为 100 μH，公差 ±10%，额定电流 60 mA，饱和电流（Isat）60 mA，直流电阻（DCR）约 9.1 Ω，封装为 0805（2012 公制，约 2.0 × 1.25 mm）。该器件为表面贴装型，适用于对体积要求严格且电流较小的滤波与去耦场合。
二、主要特点
- 高电感量：100 μH，适合对低频抑制和直流偏置下的滤波需求。
- 小型化封装：0805 体积利于高密度 PCB 布局。
- 低额定电流：60 mA，饱和电流与额定电流一致，超过该电流时电感量会显著下降。
- 比较大的 DCR：9.1 Ω，意味着在满载电流下会有明显压降和功耗（在 60 mA 时电压降约 0.55 V，功耗约 33 mW）。
三、典型应用场景
- 低功率 DC 供电滤波与去耦（如 RTC、传感器电源、低速模拟电源）。
- EMI/RFI 抑制与信号链滤波，针对低频干扰有良好抑制效果。
- 不推荐用于高电流开关电源主回路或对电能效率要求高的电源场合，因较高的 DCR 会造成较大能量损失与热量积累。
四、封装与布局建议
- 0805 小封装利于紧凑布局，但焊盘与走线应尽量短且宽，以减小附加寄生电阻与电感。
- 器件应靠近需滤除噪声的器件或电源引脚放置，避免把高电感串入大电流回路。
- 若串联有多个器件或需提高散热，请注意周围铜箔面积与过孔布置以利散热。
- 避免在器件正下方开大通孔，以减少不必要的寄生效应。
五、选型与设计要点
- 注意 DC 偏置与饱和特性：额定/饱和电流 60 mA 意味着在此电流附近电感可能下降，设计时应留有裕量。
- DCR 对电压降与功耗影响显著：在 60 mA 条件下计算得到电压降约 0.546 V，功耗约 0.033 W，需评估对系统电压与热预算的影响。
- 自谐频率（SRF）和高频特性受封装与寄生电容影响，若在高频段使用，请参考厂商测量条件或自行测量频率响应。
- 测量与仿真时使用与应用相近的频率与偏置电流，以获得更符合实际的参数。
六、测试与可靠性
- 建议使用 LCR 表在厂商规定的测量频率和偏置条件下验证电感值与 DCR。
- 遵循厂商回流焊曲线进行贴装，避免超过材料允许的温度循环导致性能劣化。
- 在长期运行中关注温升与电感衰减，特别是在接近额定电流时需定期验证性能。
七、总结
CB2012T101K 适合体积受限且电流较小的滤波与去耦场合，提供较高的电感量但伴随较大的直流电阻和较低的额定电流。设计时应重点考虑 DCR 带来的电压降与功耗、饱和电流引起的电感退化，以及频率响应与封装寄生影响，确保与实际应用工况匹配。若需更高电流或更低损耗，应优先选择 DCR 更低、额定电流更大的型号。

Product sourcing intelligence
Model, package, availability, and BOM fit reviewed before quotation.
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
BOM matching & alternatives
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Sourcing availability signal
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
Examples of how common component sourcing requests are organized.
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.
