三、关键电气性能

作为高压MLCC,该产品在电气性能上兼顾稳定性与耐高压能力:

  1. 容值精度:±10%,在额定电压及工作温度范围内保持容值稳定,减少电路参数漂移;
  2. 损耗角正切(DF):1kHz测试条件下≤2.5%,低损耗特性适合高频电路应用;
  3. 绝缘电阻(IR):25℃下≥50GΩ(或≥10¹⁰Ω·F),绝缘性能优异,降低漏电流对电路的影响;
  4. 耐电压能力:额定电压1kV下可长期稳定工作,短时间过压(如1.5kV/2s)无击穿失效;
  5. 高频特性:X7R材质的MLCC具有良好的高频响应,适合EMI滤波、射频耦合等场景。

四、温度稳定性(X7R材质优势)

X7R是EIA标准的温度系数分类,该产品的温度特性表现优于Y5V等低成本材质:

  • 低温(-55℃):容值变化率≤±15%;
  • 高温(+125℃):容值变化率≤±15%;
  • 温度范围宽、容值漂移小,适合对温度敏感的工业控制、医疗设备等场景。

五、典型应用场景

该产品因1kV额定电压与小尺寸封装,适用于以下核心场景:

  1. 开关电源(SMPS):高压输出端滤波、EMI滤波;
  2. LED驱动电源:高压侧耦合、旁路电容,提升电源效率;
  3. 工业控制电路:高压传感器接口、电机驱动电路滤波;
  4. 医疗设备:低功耗高压电路的稳定电容(如监护仪、诊断设备);
  5. 通信设备:射频前端高压耦合电容、EMI抑制;
  6. 汽车电子(可选):车载高压系统辅助滤波(需确认AEC-Q200认证)。

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
