BOCHEN 3296X-1-502 精密可调电位器产品概述

BOCHEN(博晨)3296X-1-502是一款插件式多圈精密可调电位器,属于3296X系列通用型产品,核心参数匹配5kΩ阻值、±10%精度、500mW功率等要求,广泛适用于电子仪器、电源调节、工业控制等场景,兼顾调节精度与成本优势。

一、产品核心定位与基础属性

3296X-1-502定位为通用型多圈可调电位器,区别于单圈电位器的粗略调节,其30圈设计可实现更精细的阻值设置;插件封装无需特殊贴片设备,适合传统PCB批量焊接,是替代单圈电位器提升调节精度的性价比选择。基础属性如下:

  • 系列:3296X(多圈精密型)
  • 阻值:5kΩ(标识“502”:前两位50,第三位10²倍,即50×10²=5000Ω)
  • 精度:±10%(满足一般工业/民用设备精度需求)
  • 功率:500mW(25℃环境额定功耗)
  • 温度系数:±250ppm/℃(阻值随温度变化的稳定性指标)
  • 封装:插件(直插引脚,焊接兼容性强)

二、关键参数深度解析

1. 阻值与精度

  • 阻值:5kΩ(双重标注:数字“502”+色环),实际范围4500Ω~5500Ω;
  • 精度:±10%,无需极高精度(如±1%)的场景可直接使用,如电源微调、仪器基础校准。

2. 功率额定值

额定功率500mW(0.5W),需注意温度降额:环境温度每升高10℃,最大允许功耗降低50%(如65℃时最大功耗250mW),避免电阻体过热老化。

3. 温度系数

±250ppm/℃表示:每变化1℃,阻值变化百万分之250。以25℃为基准,若温度升至75℃(变化50℃),阻值变化量为5000Ω×50×250e-6=62.5Ω,实际范围4937.5Ω~5062.5Ω,稳定性满足一般环境需求。

4. 调节圈数

30圈多圈调节,分辨率是单圈的30倍(最小步长≈5000Ω/30≈167Ω),避免调节过冲,适合精细设置(如示波器通道增益)。

三、结构与可靠性特点

3296X-1-502采用金属陶瓷电阻体,结构优势明显:

  • 旋转轴:耐磨塑料/金属轴,转动顺畅无卡滞,寿命≥10000次;
  • 引脚:抗氧化锡铅合金(无铅可选),焊接性好,无虚焊风险;
  • 外壳:密封塑料壳,防尘防轻微溅水,适应工业轻度恶劣环境;
  • 调节范围:0%~100%阻值连续调节,无死区。

BOCHEN产品出厂前经阻值精度、功率老化、温度特性测试,批次一致性达标,符合RoHS环保标准。

四、典型应用场景

结合参数特性,适用于以下场景:

  1. 电子仪器校准:示波器、信号发生器、万用表的增益/零点微调;
  2. 电源调节:线性电源输出电压微调(500mW满足调整管偏置需求);
  3. 工业控制:PLC输入阈值调节、变频器频率微调(±10%精度足够);
  4. 音频设备:调音台通道增益、功放音量微调(避免单圈突变);
  5. 家电控制:电磁炉功率调节、空调温度传感器校准(插件适合批量生产)。

五、使用与安装注意事项

  1. 焊接规范:引脚焊接温度≤260℃,时间≤3秒,避免高温伤电阻体;
  2. 调节工具:用一字螺丝刀(轴端一字槽),忌用力过大断轴;
  3. 功率限制:实际功耗低于额定值(考虑温度降额),禁止过功率;
  4. 储存条件:-40℃~85℃、湿度≤80%RH,避免潮湿氧化引脚;
  5. 清洁禁忌:忌用酒精、丙酮等腐蚀清洁剂,防止外壳老化。

六、总结

BOCHEN 3296X-1-502是性价比突出的通用多圈电位器,兼顾30圈精度、500mW功率与成本,插件封装适配传统PCB,广泛用于电子仪器、工业控制、家电等领域。参数稳定、安装方便,是替代单圈电位器提升调节精度的理想选择。

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.
