CSRV0204FTCV5R10 产品概述

一、产品简介

CSRV0204FTCV5R10 是 Viking(中文品牌:光颉)系列的金属薄膜固定电阻,封装为 0204,额定功率 250mW,阻值 5.1Ω,标准精度 ±1%,工作温度范围 -55℃ 至 +155℃。该系列采用薄膜工艺与镍阻挡层上的锡端子,具有优异的电气稳定性与可焊性,且通过 AEC‑Q200 认证,适用于汽车(非安全关键部件)与工业级电子设备。

二、主要性能参数

  • 阻值:5.1Ω
  • 精度:标准 ±1%,可选更紧公差低至 ±0.1%
  • 额定功率:250mW(常温参考)
  • 最大工作电压:标称 200V(器件结构上限,实际使用需受功率限制)
  • 温度系数(TCR):标准 ±25ppm/℃,可提供低至 ±5ppm/℃ 的低 TCR 选项
  • 工作温度:-55℃ ~ +155℃
  • 终端:镍阻挡层,表面锡覆层(优良的波峰/回流焊兼容性)
  • 封装:0204,适合自动贴片与卷带供料

三、关键特性

  • 薄膜工艺带来极低噪声和优异的长期稳定性,阻值漂移小。
  • AEC‑Q200 认证,满足汽车应用的工艺与可靠性要求(适用于非安全关键回路)。
  • 可提供极低 TCR 与超紧公差规格,便于高精度分流、电流检测与温度敏感电路设计。
  • 优质终端处理确保良好焊接性与可加工性。

四、实际使用注意

  • 功率与电压关系:虽然器件结构标称最大工作电压为 200V,但电阻两端实际允许电压受限于额定功率。根据 P=V^2/R,5.1Ω、0.25W 条件下,不超过额定功率的最大直流电压约为: Vmax = sqrt(P·R) ≈ sqrt(0.25×5.1) ≈ 1.13V。 因此在设计中必须同时满足电压与功率限制,避免过驱动造成过热失效。
  • 降额使用:在高温环境(例如 >70℃)应按厂家功率降额曲线使用,保证寿命与可靠性。
  • 焊接工艺:兼容常规回流与波峰焊,推荐遵循制造商的最高温度与时间限制以避免应力导致漂移。
  • 储存与处理:避免潮湿、高温及机械伤害,贴片元件应使用防静电措施及干燥保存。

五、典型应用

  • 汽车电子(信息娱乐、车身控制、传感器接口等非安全回路)
  • 工业控制与测量设备中的基准/分流电阻
  • 精密模拟电路、放大器偏置与反馈网络
  • 电源管理与微小电流检测场合(配合低 TCR/高精度选项)

六、选型与订购建议

  • 若对温漂与测量精度要求高,优先选择 ±5ppm/℃ TCR 与 ±0.1% 精度版本。
  • 评估实际最大工作电压时,务必按 V^2/R ≤ 额定功率 的原则计算,必要时选用更大阻值或更高功率器件以满足电压承受需求。
  • 订购时请注明封装(0204)、阻值、精度、TCR 及是否 AEC‑Q200 版本,以及包装形式(卷带/散装)。

总结:CSRV0204FTCV5R10 提供了金属薄膜电阻的低噪声、高稳定性与汽车级可靠性,适合需要高精度与长期稳定性的工业与车用电子设计。在选型与布局时,请结合功率、环境温度与电压条件进行合理降额与验证。若需器件数据表(包含功率降额曲线、温度循环与焊接规范)或样品测试建议,请联系供应商或指定代理。

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
