ZMM4V3 是一种由永裕泰(YONGYUTAI)品牌生产的稳压二极管,属于独立式配置。这种元器件专门设计用于提供稳定的电压输出,广泛应用于各种电子设备中,特别是在需要精确电压控制的场景。
ZMM4V3 的主要功能是提供一个稳定的输出电压,尽管输入电压可能会有所波动。其标称稳压值为 4.3 V,实际稳压范围在 4 V 到 4.6 V 之间。这使得该元器件非常适合用于需要精确电压控制的应用场景,如电子仪表、通信设备、医疗设备等。
该稳压二极管具有 500 mW 的功率处理能力,这意味着它可以承受一定的电流和电压变化而不至于过热或损坏。这种功率水平足以满足大多数中小型电子系统的需求。
ZMM4V3 的动态阻抗(Zzt)为 75 Ω,这是一个相对较低的值,表明在工作状态下,该元器件对输入信号的影响较小,能够提供更稳定的输出。
该元器件采用 LL-34 封装形式,这是一种常见的双脚封装,易于安装和焊接,适合各种 PCB 设计。
在电子仪表和测量设备中,稳定的参考电压至关重要。ZMM4V3 可以作为参考电压源,确保测量结果的准确性。
通信设备中,稳定的电压供给对于信号处理和传输质量有着重要影响。ZMM4V3 可以用于基带处理、射频模块等部分,确保信号稳定性。
医疗设备对电压稳定性要求非常高,因为任何电压波动都可能影响设备的性能和安全性。ZMM4V3 可以用于心电图机、血压计等医疗设备中。
在消费电子产品如智能手机、平板电脑等中,稳压二极管可以用于各种模块的电源管理,例如音频模块、传感器模块等。
由于 ZMM4V3 有一定的功率处理能力,但仍需要注意热管理。建议在安装时提供适当的散热措施,以确保元器件在长时间运行中保持正常工作状态。
在电路设计中,应确保输入电压在指定范围内,并且考虑到负载条件下的电流需求。同时,建议添加适当的滤波和保护电路,以防止过电压或过电流对元器件造成损害。
在焊接过程中,应遵循标准的焊接流程,避免过热或机械应力对元器件造成损害。
ZMM4V3 是一种功能强大、性能可靠的稳压二极管,广泛适用于各种需要精确电压控制的电子系统。其独立式配置、500 mW 功率处理能力以及低动态阻抗,使其成为许多工程师和设计师的首选元器件。通过合理的设计和安装,可以充分发挥 ZMM4V3 的性能优势,确保电子设备的稳定运行和高可靠性。
Request for quote
Use the form for single models, category sourcing, and multi-line BOM requirements.
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.
