KNSCHA 14D561K68RV0007是一款高压径向引线压敏电阻,属于科尼盛(KNSCHA)14D系列,专为中等强度瞬态过压防护设计。其核心应用场景覆盖:
标称压敏电压为560V(型号中“561”表示56×10¹V),公差±10%,实际区间为504V~616V。这一精准公差确保:
当浪涌电压触发器件导通后,钳位电压稳定在920V左右,可将后级电路的过压限制在安全范围内(如MOS管、电容的耐压阈值内)。
该产品采用径向引线封装,关键设计特点:
若需更高浪涌能力,可升级至14D561K100RV0007(浪涌5kA);若电压需求更低,可选择14D471K(470V±10%)。
以充电桩交流输入防护为例:
该产品凭借精准的电压参数、可靠的浪涌防护能力,成为工业电源、新能源等领域高压过压保护的优选器件。

Product sourcing intelligence
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
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.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
