3296P-1-103LF 产品概述
一、产品简介
3296P-1-103LF 为 BOURNS 出品的一款多圈可调电阻（电位器），阻值 10kΩ，精度 ±10%，额定功率 500mW，圈数 25 圈，封装为插件式三引脚，外形尺寸约 9.5 × 4.8 mm。该型号适用于需要较细微调节的电路场合，常见于模拟电路的偏置、滤波、增益与零点校准等应用。
二、主要电气与机械参数
- 阻值：10 kΩ
- 精度：±10%（出厂阻值公差）
- 额定功率：500 mW（使用时需留意散热与环境温度）
- 圈数：25 圈，多圈结构便于进行细致调节与重复定位
- 引脚与封装：插件三引脚，适合直接穿孔焊接到 PCB；外形约 9.5×4.8 mm，紧凑型设计便于密集布局
三、特性与优势
- 多圈设计带来更高的调节分辨率，适合需要细微调节或多次微调的场合。
- 通过式插件封装，便于快速装配与现场更换。
- BOURNS 品牌品质保证，材料与接触可靠性良好，适用于原型与中小批量产品。
四、典型应用
- 模拟前端增益与偏置微调
- 滤波器中心频率或截止频率的校准
- 传感器零点/量程微调与标定
- 工业控制、仪器仪表以及消费类电子的调节点
五、使用与安装建议
- 焊接时控制焊接温度与时间，避免对陶瓷/金属膜材料造成损伤。
- 调节应使用与端蓋匹配的旋具，避免用力过猛导致机械损伤或游丝脱落。
- 若工作环境温度较高或长期通电，注意降低载荷或采用散热措施，避免超过 500 mW 额定功率。
- 对于要求长期稳定性的应用，建议在调试后做固定处理（如点胶或机械锁定）以防震动致位移。
六、选型与替代方案
若需要更高精度或更大功率，可考虑误差更小（±5%、±1%）或功率更高的同类多圈电位器。市场上 Vishay、ALPS、Piher 等厂商也有类似阻值与多圈规格的产品，可按尺寸、寿命与耐温要求比选。
七、总结
3296P-1-103LF 是一款结构紧凑、调节精细的 10kΩ 多圈可调电阻，适合在 PCB 上作为微调元件使用。其 25 圈设计适合需要高分辨率设置的场合，500 mW 的功率等级适用于低功耗或间歇调节的应用场景。选型时应结合实际工作温度、寿命与调节频次等因素，确保长期可靠运行。

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.
