    • 压敏电压是指压敏电阻在特定电流下(通常为 1mA)的电压值。271KD14 的压敏电压为 270V,允许有 ±10% 的偏差,确保在正常工作电压下,压敏电阻不会导通,而在过电压情况下能够迅速响应。
  • 峰值浪涌电流 (Peak Surge Current): 4.5kA

    • 峰值浪涌电流是指压敏电阻能够承受的最大瞬时电流。271KD14 能够承受高达 4.5kA 的浪涌电流,适用于需要高浪涌保护的应用场景,如电源输入端的保护。
  • 最大工作电压 (Maximum Working Voltage):

    • AC: 175V
    • DC: 225V
    • 最大工作电压是指压敏电阻能够长期稳定工作的最高电压。271KD14 在交流电路中的最大工作电压为 175V,在直流电路中的最大工作电压为 225V,确保在正常电压范围内,压敏电阻不会误动作。
  • 能量 (Energy): 70J

    • 能量参数表示压敏电阻能够吸收的最大能量。271KD14 能够吸收 70J 的能量,适用于需要高能量吸收能力的电路保护。
  • 钳位电压 (Clamping Voltage): 455V

    • 钳位电压是指压敏电阻在承受最大浪涌电流时的电压值。271KD14 的钳位电压为 455V,确保在过电压情况下,电路中的电压不会超过此值,从而保护后续电路。
  • 静态电容 (Static Capacitance): 740pF @ 1kHz

    • 静态电容是指压敏电阻在特定频率下的电容值。271KD14 的静态电容为 740pF @ 1kHz,适用于对电容值有一定要求的电路设计。

3. 产品特点

  • 高浪涌电流承受能力: 271KD14 能够承受高达 4.5kA 的峰值浪涌电流,适用于高浪涌电流环境下的电路保护。
  • 高能量吸收能力: 70J 的能量吸收能力,确保在过电压情况下,能够有效吸收能量,保护电路。
  • 宽工作电压范围: 最大工作电压 AC 175V,DC 225V,适用于多种电路环境。
  • 低钳位电压: 455V 的钳位电压,确保在过电压情况下,电路中的电压不会过高,保护后续电路。
  • 低静态电容: 740pF 的静态电容,适用于对电容值有一定要求的电路设计。

4. 应用领域

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
