TL431A 是一款高精度可调式并联(分流)型电压基准与误差放大器,品牌为 Slkor(萨科微),SOT-23 封装。器件在 0℃+70℃ 工作温度范围内稳定工作,提供可调输出电压范围 2.5V36V,适用于各种需要精密基准和反馈控制的电源与检测场合。
SOT-23 小体积便于 PCB 高密度设计。选型时注意额定电流与功耗余量,若电压差较大且分流电流接近 100mA,应考虑采用散热更好的封装或外加散热元件,或使用功率较高的替代方案。
Slkor(萨科微)TL431A 在 0℃~+70℃ 工作条件下,以 ±0.5% 初始精度、50 ppm/℃ 的低温漂和最高 100mA 分流能力,提供了小体积且精密的可调参考解决方案。适合用于电源反馈、检测保护与精密基准场景。设计时重点关注最低阴极电流、器件功耗与稳定性补偿,以保障长期可靠性与精度。

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.
