RLS102-501M是RUILON(瑞隆源)推出的一款轴向引线封装瞬态过压保护器件,针对小型化电路的浪涌防护需求设计,具备宽温适应、低电容、高浪涌耐受等核心特性,可广泛应用于智能家居、通信模块、工业传感器等场景。
该器件的核心定位是小型化电路的低成本浪涌防护解决方案,聚焦解决常见过压问题:
RLS102-501M的参数设计平衡了防护性能与电路兼容性,核心参数如下:
击穿电压标称500V,精度±20%,实际触发范围为400V~600V。这一设计既避免了因精度过高导致的“误触发”(正常电压波动下不动作),又能在过压达到保护阈值时快速导通,将电压钳位在安全范围。
正常工作状态下绝缘电阻≥100MΩ,在500V偏置电压下,漏电流仅约5μA(计算值:I=V/R=500V/100MΩ)。低漏电流特性可防止对敏感电路(如低功耗MCU、模拟传感器)造成干扰,不影响电路正常功能。
电容标称1pF,属于高频兼容型设计。在通信模块(如蓝牙、WiFi)的信号端口应用中,低电容不会导致信号衰减或相位偏移,确保数据传输稳定。
可承受1kA(8/20μs波形) 的单次浪涌脉冲,能有效抵御常见浪涌场景(如家庭电网的开关浪涌、户外设备的雷电感应)。多次浪涌测试后,器件性能无明显衰减,可靠性符合工业级要求。
工作温度范围为**-45℃~+85℃**,覆盖从低温户外(如北方冬季)到高温工业控制柜(内部环境温度)的场景;轴向引线封装直径仅2.6mm,长度紧凑,适合小型化产品(如智能手环充电模块、小型传感器)的集成。
采用标准轴向引线封装,引脚焊接方便,适配传统插装工艺;直径2.6mm的紧凑体积,可在PCB上实现高密度布局,无需额外占用过多空间。
RUILON采用高稳定性陶瓷基材料,器件内部结构牢固;引线与主体的焊接工艺经老化测试验证,可承受多次温度循环与机械振动,适合批量应用于对可靠性要求较高的领域。
RLS102-501M的参数特性使其适配多种小型化电路:
综上,RLS102-501M凭借小型化、宽温、低电容与高浪涌耐受的综合优势,成为小型电子设备过压防护的高性价比选择,适合对成本与体积敏感的应用场景。
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.
