0805B105K500CT 片式陶瓷电容产品概述

一、产品型号与核心参数解读

0805B105K500CT是华新科(Walsin)推出的X7R温度系数片式陶瓷电容,型号各部分对应核心信息清晰:

  • 0805:封装规格(英寸制,0.08×0.05英寸,即公制2.0mm×1.25mm);
  • 105:容值编码(10×10⁵ pF = 1μF);
  • K:容值精度(±10%);
  • 500:额定直流电压(50VDC);
  • CT:封装/编带细节(标准SMT编带包装,适配自动化贴装)。

核心参数明确:容值1μF、精度±10%、额定电压50VDC、温度系数X7R、封装0805,属于工业级通用型陶瓷电容。

二、封装与物理特性

该电容采用0805表面贴装(SMT)封装,是电子行业应用最广泛的小型封装之一,具备以下物理优势:

  1. 尺寸紧凑:公制尺寸2.0mm(长)×1.25mm(宽)×1.0mm(典型厚度),适配高密度PCB设计,可有效节省电路板空间(尤其适合便携设备);
  2. 轻量化:单颗重量约2mg,对整机重量要求严格的场景(如可穿戴设备、无人机)友好;
  3. 焊接兼容性:支持回流焊、波峰焊等主流SMT工艺,焊接温度范围(260℃以下回流焊峰值)符合行业标准,无特殊焊接要求;
  4. 机械强度:陶瓷介质与电极结构稳定,抗振动(10-2000Hz、加速度≤10g)、抗冲击性能满足一般工业场景需求。

三、电性能关键指标

作为X7R型陶瓷电容,其电性能兼顾容值稳定性与损耗控制,核心指标如下:

  1. 容值与精度:标称容值1μF,精度±10%,覆盖一般电路对容值的要求(如滤波、耦合电路无需极高精度);
  2. 额定电压:50VDC,直流应用中可直接匹配低中压电源(12V/24V工业电源、5V消费电子电源),交流应用需按降额规则(通常降额至额定电压的70%以下,即35VAC以内);
  3. 损耗角正切(tanδ):1kHz、25℃条件下典型值≤1.5%,最大值≤2%,低损耗可减少电路功率消耗,适合电源滤波等对效率要求较高的场景;
  4. 绝缘电阻(IR):25℃、50V直流条件下,绝缘电阻≥10⁹Ω·μF,高绝缘性可避免漏电流干扰,延长设备使用寿命。

四、温度特性与稳定性

X7R温度系数是该电容的核心优势之一,具体特性:

  • 温度范围:工作温度为-55℃至+125℃,覆盖工业级宽温环境(户外设备、汽车辅助电路);
  • 容值漂移:全温度范围内容值变化≤±15%,远优于Y5V等低价电容(Y5V容值漂移可达±20%~-80%),适合对温度稳定性要求较高的电路;
  • 温度循环可靠性:经过-55℃~+125℃、1000次循环测试后,容值变化≤±10%,绝缘电阻无明显下降,满足长期宽温应用需求。

五、典型应用场景

0805B105K500CT因尺寸小、稳定性好,适配多领域通用电路:

  1. 消费电子:智能手机、平板的电源滤波(去除电源纹波)、信号耦合(音频/射频信号传输);
  2. 工业控制:PLC、传感器模块的去耦电容(抑制噪声干扰)、电源模块的储能电容;
  3. 通信设备:路由器、基站的直流电源滤波(稳定电压)、射频前端的匹配电容;
  4. 汽车电子:车载导航、仪表盘的辅助电源电路(低功耗场景,部分型号符合AEC-Q200车规认证)。

六、品牌与可靠性保障

华新科(Walsin)作为全球知名陶瓷电容厂商,该产品具备可靠品质:

  1. 环保合规:符合RoHS 2.0、REACH等国际标准,无铅无卤,适配绿色制造;
  2. 可靠性测试:通过高温存储(125℃、1000h)、湿度老化(85℃/85%RH、1000h)、振动测试,满足IEC 60384-8行业标准;
  3. 供应链稳定:量产能力强,交货周期短,适合批量生产需求。

总结:0805B105K500CT是一款高性价比通用型X7R片式陶瓷电容,兼具尺寸紧凑、温度稳定、低损耗等特点,可广泛应用于消费电子、工业控制、通信等领域,是电源滤波、信号耦合的优选元件。

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.
