CSA0603X7R223K500JT 产品概述

一、概述

CSA0603X7R223K500JT 是 HRE(芯声)推出的一款表面贴装多层陶瓷电容(MLCC),规格为 0603(约 1.6 × 0.8 mm),标称容量 22 nF,容差 ±10%,额定电压 50 V,介质类型 X7R。该型号面向一般电子产品的去耦、耦合、滤波与旁路应用,兼顾体积小、成本低与良好频率响应的性能要求。

二、主要参数与特性

  • 容值:22 nF(223 表示 22 × 10^3 pF)
  • 容差:±10%(K)
  • 额定电压:50 V
  • 介质:X7R(温度特性:−55°C 至 +125°C,允许容值变化范围相对较小,属 Class II)
  • 封装:0603(英制 0603,对应约 1.6 mm × 0.8 mm)
  • 包装:卷带(JT 后缀常指卷带包装,具体卷盘数量请参见厂商数据表)

关键特性:

  • 适用于高密度 SMT 布局的超小型封装;
  • X7R 具有比 NP0(C0G)更高的体积容值,适合中等稳定性与较高容量需求的场合;
  • 成本与封装效率适中,适合批量应用。

三、电气与环境注意事项

  • X7R 为温度相关的介质,实际容值随温度与时间会有变化(温度区间内允许有一定百分比偏差),在温度关键或高精度滤波场合应验证性能;
  • MLCC 存在直流偏压效应:在施加直流电压时(尤其接近额定电压),有效电容会下降。22 nF/0603 在 50 V 下的偏压效应通常低于大容量型号,但对于对容量要求严格的电路(如时间常数、滤波截止)建议按经验或测量结果做偏压裕量;
  • 陶瓷电容存在老化现象(随时间缓慢下降),应在可靠性评估中考虑。

四、应用场景

  • 电源去耦与旁路(各类数字芯片、MCU、电源模块附近);
  • 中高频滤波(LC/RC 滤波器、EMI 抑制);
  • 耦合/耦合电路与旁路网络;
  • 消费电子、通讯设备、工业控制等需要小体积与中等稳定性的场合。

五、封装与焊接建议

  • 推荐采用标准 SMT 回流焊工艺(参照 JEDEC/IPC 回流温度曲线,峰值温度通常 ≤ 260°C);避免超出厂商给定的回流曲线;
  • 推荐的 PCB 焊盘与过孔设计应保证良好焊点,减小焊膏体积以避免机械应力集中;参考厂商推荐的 land pattern;
  • 注意机械应力:在 PCB 装配、螺丝固定或板弯曲时,避免在电容位置产生应力,以防裂片或失效;
  • 对于敏感件或长期贮存,按厂商说明进行保管,必要时进行烘烤以防潮湿影响焊接品质。

六、可靠性与选型要点

  • 如需用于汽车、航空或医用等严苛环境,请向供应商确认是否有 AEC‑Q200 或其它认证版本;默认型号更多面向消费与工业级应用;
  • 在关键电路中,建议在样机阶段进行实际温度、偏压和可靠性测试(含湿热、振动、热循环)以确认满足系统需求;
  • 如电路对电容容差与温漂要求高,考虑使用 NP0/C0G 或配合采用更大容量或并联多个电容以减小偏差与偏压影响。

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
