821KD10 产品概述
产品简介
821KD10 是一款由台湾君耀（Brightking）生产的压敏电阻，具有压敏电压为820V，公差为±10%的特性。这款压敏电阻采用10mm的封装，并以散装方式提供，适用于各种电气和电子应用场景。压敏电阻是电气保护元件，用于保护敏感设备免受瞬态电压（如浪涌和过压）对其电路造成的损害。
主要特性
- 压敏电压：821KD10 的压敏电压为820V，能够在电压超过这一值时迅速导通，提供低阻抗通路，有效分散过大的瞬态电压。
- 公差：±10%的公差意味着其绝缘性能和电气特性具有一定的灵活性，适应性高，可以在多种工作环境中保持良好的工作性能。
- 封装形式：10mm的封装设计使其具有紧凑的体积，便于在PCB（印刷电路板）上安装，同时也有助于节省空间。
- 散装供应：以散装形式提供，这种方式有利于大规模生产和装配的灵活性，降低采购和使用成本。
应用领域
821KD10 压敏电阻广泛应用于各类电气设备和电子产品中，特别是需要过电压保护的场合。主要应用领域包括但不限于：
- 家用电器：如冰箱、洗衣机等，这些设备往往需要保护其内部电路不受瞬态电压影响。
- 计算机和通讯设备：在网络设备、服务器和计算机内部，压敏电阻防止高电压冲击可能导致的数据丢失或设备损坏。
- 工业设备：在电机驱动、控制系统等工业应用中，821KD10 提供了有效的过压保护，确保操作安全性。
- 电力系统：在变电站、配电箱等电力系统中，压敏电阻防止雷击或电网故障情况下的电压突变影响设备的正常运行。
工作原理
压敏电阻的工作原理基于电阻随电压变化而变化的特点。其在正常操作电压下保持高阻抗状态，而当受到高于额定值的电压时，电阻值会迅速下降，形成通路，允许电流流过，进而将过高的电压限制在一个安全范围内。当过电压消失后，压敏电阻又会快速恢复到其高阻抗状态，从而不会影响正常工作电压。
性能参数
在选择和使用821KD10 压敏电阻时，用户需要关注以下几个性能参数：
- 耐压能力：在使用过程中，必须确保工作电压不超过821KD10的额定压敏电压820V。
- 响应时间：压敏电阻具有较快的响应时间，通常只有纳秒级别，这确保了其在瞬态电压出现时能够迅速响应。
- 稳定性与寿命：优秀的压敏电阻在长期使用中表现出良好的稳定性和相对较长的使用寿命，适合长期在恶劣环境下工作。
结论
821KD10 压敏电阻是保护电气和电子设备的重要元件，其820V的压敏电压、优秀的电气特性以及适应多种应用场景的能力，使其成为市场上广泛使用的压敏电阻之一。无论是家用电器、工业控制、还是通讯设备，只要涉及到电压保护和过电压保护，821KD10 都会是一个理想的选择。选择合适的保护元件，不仅能够延长设备的使用寿命，还能提高系统的安全性和可靠性。

Product sourcing intelligence
Model, package, availability, and BOM fit reviewed before quotation.
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
BOM matching & alternatives
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
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.
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.
