华新科0402B104K100CT陶瓷电容器产品概述

一、产品基本信息

0402B104K100CT是华新科(Walsin)推出的多层陶瓷电容器(MLCC),属于通用型陶瓷电容产品线。型号标识对应核心属性:

  • “0402”:英制表面贴装封装代码;
  • “104”:容值100nF(10⁴ pF,3位数标识法);
  • “K”:容值精度±10%;
  • “100”:额定电压10V;
  • “CT”:产品系列及封装后缀。

该产品采用X7R介质材料,平衡了容值稳定性与温度适应性,适用于低压电子电路的滤波、耦合、旁路等基础功能。

二、关键性能参数解析

1. 容值与精度

容值为100nF(0.1μF),精度±10%,满足绝大多数通用电路的偏差要求(无需高精度场景即可覆盖)。容值采用行业标准“3位数标识”,前两位为有效数字(10),第三位为10的幂次(4,即10⁴ pF=100nF),识别直观。

2. 额定电压

额定电压10V,属于低压陶瓷电容范畴,适配5V、3.3V等主流低压供电系统,可有效避免过压击穿风险(实际工作电压需≤额定值)。

3. 介质特性

采用X7R介质,符合EIA温度特性标准:

  • 低温范围:-55℃;
  • 高温范围:+125℃;
  • 容值变化率:≤±15%(温度范围内)。

相比Y5V(高容值但温度稳定性差)和COG(高精度但容值低),X7R兼顾了稳定性与温度适应性,是通用场景的优选介质。

三、封装特性与物理尺寸

产品采用0402封装(英制),对应公制尺寸为1005(1.0mm×0.5mm),是小型化表面贴装的典型代表,物理参数如下:

  • 长度:1.0±0.2mm;
  • 宽度:0.5±0.2mm;
  • 厚度:0.5±0.1mm(典型值);
  • 焊盘尺寸:推荐0.6mm×0.3mm(适配回流焊工艺)。

该封装体积小、重量轻,可显著提升PCB布局密度,适合手机、智能穿戴等小型化设备。

四、环境适应性与可靠性

1. 温度范围

工作温度范围为**-55℃~+125℃**,覆盖工业级与汽车级部分场景(需结合具体应用的认证要求),极端温度下仍保持稳定电气性能,避免电路功能异常。

2. 湿度与焊接兼容性

陶瓷介质防潮性优异,可在相对湿度≤95%(无凝露)环境下长期工作;产品符合RoHS 2.0、REACH环保标准,支持无铅回流焊(温度峰值260℃,持续时间≤10秒),焊接可靠性高,批量一致性好。

3. 寿命与稳定性

额定条件下平均无故障时间(MTBF)达数十万小时,长期使用后容值漂移率≤5%,满足通用电路的可靠性需求。

五、典型应用场景

0402B104K100CT因体积小、性能均衡,广泛应用于:

  1. 消费电子:手机、平板、智能手表的电源滤波(VCC端旁路)、音频耦合;
  2. 工业控制:小型PLC、传感器模块的信号滤波、电源稳压辅助;
  3. 汽车电子:车载USB接口、仪表盘背光电路的低压滤波(需确认汽车级认证);
  4. 通信设备:路由器、WiFi模块的射频耦合、电源噪声抑制;
  5. 物联网设备:低功耗传感器节点、智能门锁的电源滤波与信号耦合。

六、总结

华新科0402B104K100CT是一款高性价比通用MLCC,兼具小型化封装、稳定的X7R介质特性与低压适配能力,可覆盖绝大多数低压电子电路的基础电容需求。产品符合行业标准,可靠性与一致性优异,是消费电子、工业控制等领域的优选组件。

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
