BOCHEN 3296X-1-104 精密可调电位器产品概述

一、产品定位与核心属性

BOCHEN(博晨)3296X-1-104是一款插件式多圈精密可调电位器,属于3296X系列标准规格,专为电路参数的精细微调设计。其核心标识“104”对应标称阻值100kΩ,“X”代表多圈结构(30圈),“1”为精度等级(±10%),是工业控制、仪器仪表等领域常见的微调元件,兼顾可靠性与成本效益。

二、关键技术参数深度解析

该产品的核心参数直接决定了应用场景,具体解析如下:

  1. 阻值与精度:标称阻值100kΩ(编码“104”=10×10⁴Ω),精度±10%——出厂阻值偏差范围为-10%至+10%,满足大部分非超高精度电路的微调需求,无需额外校准即可直接使用;
  2. 额定功率:500mW(0.5W)——连续工作时的最大功率容量,若环境温度超过25℃,需按降额曲线使用(如70℃时需降额至300mW),避免电阻体过热老化;
  3. 温度系数:±250ppm/℃——每变化1℃,阻值变化±250×10⁻⁶。例如从25℃(常温)升至85℃(工业高温),阻值变化约±1.5%,稳定性满足一般工业应用;
  4. 调节圈数:30圈——多圈设计相比单圈电位器,调节分辨率提升30倍,可实现0.1%级别的精细调整,避免单圈“过调”导致的参数偏差;
  5. 封装形式:插件式(通孔安装)——适合PCB波峰焊或手工焊接,焊接点牢固,抗振动性能优于贴片封装,适配工业设备严苛环境。

三、设计特点与工艺优势

BOCHEN 3296X-1-104采用成熟工艺,核心特点包括:

  • 陶瓷基体:电阻体附着于高温陶瓷基体,耐高温、耐老化,长期使用阻值漂移小;
  • 金属膜电阻体:电阻膜均匀性好,阻值一致性高,配合30圈调节机构实现平滑阻值变化;
  • 耐磨触头:滑动触头采用合金材料,减少调节磨损,使用寿命可达10000次以上;
  • 标准化尺寸:符合3296系列通用封装,可直接替换同系列其他阻值产品,兼容性强。

四、典型应用场景

该产品因参数平衡,广泛应用于:

  1. 仪器仪表校准:万用表、示波器的基准电压/电流微调,30圈精度满足0.5%以内校准误差;
  2. 工业控制:PLC输入模块的传感器信号调理(压力、温度传感器零点/量程调整),抗振动封装适配现场工况;
  3. 通信设备:射频电路阻抗匹配微调(基站天线驻波比调整),500mW功率应对中等射频信号;
  4. 电源电路:线性电源输出电压微调(如5V电源±0.1V精度调整),温度系数适配电源工作环境;
  5. 汽车电子:车载传感器(氧传感器、节气门位置传感器)信号校准,插件封装抗汽车振动。

五、选型与使用注意事项

为确保性能与寿命,需注意:

  1. 功率降额:环境温度>25℃时,每升高10℃降额10%,避免过热;
  2. 焊接规范:烙铁温度≤260℃,焊接时间≤3秒/引脚,防止损坏电阻体;
  3. 调节方式:用专用一字螺丝刀调节,避免用力过大导致触头磨损;
  4. 存储条件:常温干燥环境存储,避免潮湿、腐蚀性气体;
  5. 替换原则:需确保阻值、精度、圈数、封装一致,3296X系列不同阻值仅阻值差异,结构兼容。

该产品以平衡的性能参数和可靠的工艺,成为中低端微调场景的主流选择,可满足多数工业与民用设备的参数微调需求。

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.

Package confirmation Typical RFQ workflow

A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.

Mixed BOM triage Typical RFQ workflow

The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.

Obsolete-part review Typical RFQ workflow

Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.

Small-batch request Typical RFQ workflow

Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.

Repair batch evidence Typical RFQ workflow

When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.

Replenishment inquiry Typical RFQ workflow
