TLJR476M006R3200 产品概述

一、产品概要

TLJR476M006R3200 是 AVX 出品的一款固体钽贴片电容,标称容量 47 μF,额定电压 6.3 V,容差 ±20%。工作温度范围宽(-55 ℃ 至 +125 ℃),适用于要求中等容量、较高温度稳定性的贴片应用。外形为 CASE‑R‑2012‑12,(公制尺寸约 2.0 × 1.25 mm)小型封装,适合空间受限的 PCB 布局。

主要规格摘要:

  • 容值:47 μF(±20%)
  • 额定电压:6.3 V
  • 工作温度:-55 ℃ 至 +125 ℃
  • 等效串联电阻(ESR):3.2 Ω @ 100 kHz
  • 品牌:AVX
  • 封装:CASE‑R‑2012‑12(约 2.0 × 1.25 mm)
  • 极性:有极性(钽电容,必须正确极性安装)

二、主要电气特性与含义

  • 容值与容差:47 μF ±20% 适合做电源滤波、退耦和储能用途,对制造容差要求不高的设计适用。
  • 额定电压与工作电压:6.3 V 额定电压决定了最大允许直流偏压,钽电容对反向电压极为敏感,必须保证实际运行电压和浪涌电压在安全范围内。
  • 温度性能:-55 ℃ 至 +125 ℃ 的工作范围保证在极端环境下仍能保持功能,适合汽车电子(非高可靠汽车 AEC-Q? 请参见具体数据表)、工业控制和通信设备等应用。
  • ESR(3.2 Ω @100 kHz):相对较高的 ESR 表明该型号在高频瞬态去耦和大纹波电流下不如低 ESR 型号表现优秀,更适合低频滤波与大容量备用电源滤波,而非作为高频高速去耦的首选元件。

三、应用场景

  • 低频电源滤波与旁路:平滑电源总线、抑制低频纹波。
  • 能量储备与稳压电路:为小至中等功率负载提供短时能量供应。
  • 工业与通信设备:在中温度、空间受限的场所用于滤波、去耦。
  • RTC / 备份电路:为低泄漏备份电源提供稳定容量(注意极性与漏电特性)。

不建议将本型号用于高频点对点去耦、开关电源高频输出直连或大纹波电流的场合,除非在电路中加入额外的低 ESR 电容或阻尼网络。

四、选型与设计注意事项

  • 极性连接:钽电容为有极性元件,必须严格遵守正负极方向,避免反向电压。
  • 电压裕量(降额):为提高可靠性,应考虑对额定电压进行适当降额。许多设计实践中建议在关键或高可靠性应用中将实用电压降至额定电压的 50%(视具体应用和厂商建议而定),以降低因浪涌或过压引发的失效风险。请以 AVX 官方数据表和应用说明为最终准则。
  • 纹波电流与热:由于 ESR 相对较高,会产生一定的热量。设计时应评估实际纹波电流和温升,必要时并联低 ESR 元件或选择更高规格型号。
  • DC 偏压影响:钽电容容值随直流偏压的变化相对稳定,但仍应参考厂商数据表上的容量-偏压曲线,确保工作点满足设计要求。

五、焊接、装配与可靠性

  • 焊接工艺:遵循 AVX 的焊接温度曲线与回流参数。避免过高的回流峰值温度和频繁重复回流,以减少热应力对内阻和寿命的影响。
  • 贴装与检测:注意极性标识,元件极片方向应与 PCB 严格匹配。装配后建议进行极性/短路检测。
  • 储存与防护:按一般贴片元件储存规范管理,避免潮湿、强酸碱、长时间高温暴露。必要时遵循产商的湿敏等级说明,进行回流前必要的烘烤处理。
  • 失效模式:固体钽电容在极端过压或浪涌条件下可能发生短路。设计中应考虑限流措施(如串联电阻或熔断保护)以提升系统安全性。

六、选型建议与替代方案

  • 若应用要求低 ESR、高频去耦或大纹波承载能力,建议并联低 ESR 的陶瓷电容(如多层陶瓷)或选择 low‑ESR 钽电容/铝电解电容替代。
  • 在空间允许且需更高可靠性的场合,可考虑更高额定电压或更大尺寸封装的钽型号以减少电压应力。
  • 选用前请参考 AVX 官方数据表获取完整的电气特性、寿命及热性能曲线,并根据系统需求进行环境应力和老化评估。

如需更详细的机械尺寸、回流曲线、寿命与失效率数据或推荐 PCB 封装样式(land pattern),建议下载 AVX 对应型号的原厂数据手册或提供具体应用条件,以便给出更精确的工程建议。

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.
